VIRUS & SPYWARE

Looking after your Computer

If you are going to work and do a lot of browsing on the Internet, the first thing you need to learn is how to take care of your computer.

It is far better that you take the trouble to look after your computer regularly, rather than have it freeze or crash when you lose everything on it, at which time you’ll have to pay out a lot to have it fixed.

Here are some tips to prevent disasters:

1) Set your virus checker to update itself automatically. This way, it is always updated with the latest protection.

2) Scan your computer daily when you finish working on it.

3) If on a certain day you happen to download many pages, software, programs, zipped files, exe files, etc., immediately after downloading everything, scan your computer. This way, just in case a virus existed in anything you downloaded, you will catch it in time before it infects your entire Hard Drive.

4) Use your online scanner to scan your computer once a week.

5) Use your adware/spyware checker once a week.

6) Do not open any attachments in emails from people you do not know.

7) Do not open any attachments even from people you do know, if you are not expecting anything from them.

8) A virus could replicate itself to everyone on the address book and send itself out by email, without the owner even knowing this has been done.

9) Do not download free music on the Internet – these free sites are always infected.

10) Do not download any free games from the Internet.

11) Adult sites are particularly prone to viruses.

12) Back up all your data on a daily basis. Use floppy disks, flash drives, memory sticks, zip disks, CD-Roms, etc.

13) Print out contracts, payment forms, agreements and all legal documents and file them away in a ring-binder.

14) Try not to keep anything to do with your finances, payment details, payment processor passwords, credit card details, etc. on your computer.

15) A hacker could easily access all these details, if they are anywhere on your computer.

Sadly, despite all these precautions your computer might still get infected, as the people who invent these malicious programs are getting even sneakier.

When this happens, the easiest way to rid your computer of a virus is by rebooting your computer. This is not as difficult as it may sound, and if you learn how to do this yourself you could save yourself hundreds of dollars in repair bills.

5 Mac Security Tips You Can’t Live Without

So, you’ve bought a new Macintosh, and now you may be wondering how to make it safer. There are several things that you can do which will protect your Mac from viruses and hackers. Macs are already very difficult to hack, but don’t let that fact allow you to become lenient with your security.

1. Download all of the software updates available. This seems like a no-brainer, but some Mac users forget to download the newest updates. You can even set your computer to automatically download new updates. However, some dial-up users encounter trouble when trying to downloaded updates. If you are a dial-up user, the best suggestion is to leave your Mac on overnight and let it download. Apple releases many programs that fix bugs in iLife applications, and in Mac OS X. Probably the most important of these updates are the security updates. Apple periodically offers security updates for its operating systems (Panther and Tiger).

2. Be careful what you download. Some people use P2P downloads for Macintosh (I.E. Poisoned). Be careful when downloading using a P2P because you do not know where the music or file is coming from. Some P2P users specifically make corrupted files to send via music downloading programs. Generally, it is a good idea to stick to iTunes, because those files are ACC Protected and offered through Apple so they certainly won’t have viruses.

3. Choose the best and safest Internet Browser. Safari comes standard on all new Macs as part of iLife. However, some people do not enjoy Safari as much as others. Some say that Safari is not as safe from hackers as other browsers. Safari can also be a problem if you are going to a web page that requires a version of Internet Explorer or Netscape to view it. You can download Internet Explorer and Netscape for Mac, but again, some believe that these browsers are not as safe from hackers. Many people believe that Mozilla Firefox (my personal favorite) is the safest browser to use because of its customizable features. Firefox is available for downloading on the Macintosh.

4. Don’t be afraid to buy anti-virus software. If you have to download files from the internet as part of a job or hobby, then it is probably a good idea to have some sort of anti-virus software on your Macintosh. Apple provides a wide-variety of anti-virus software that is constantly updated.

5. Finally, keep an eye on those e-mail attachments and instant messages. Some hackers have programmed viruses to IM you from one of your friends’ screen names. Don’t click on any link without knowing what it is first. Most e-mail providers use virus scans automatically, but you should always be extra careful when downloading an attachment. If it is from someone you do not know, don’t trust it.

Apple computers are very safe from hackers, but they can always be improved. Keeping a computer safe, and running well requires a great amount of time and energy. Just remember that if your computer is safe, your Apple experience will be much more rewarding.

How to Avoid Getting Ripped-Off Online

noreply@blogger.com (meor) — Wed, 13 Jun 2007 15:26:00 +0000

by: Jim Edwards

Online security is one of the top catch phrases these days, but hardly anybody knows what it means and worse, most home computer users think security only applies to corporations and online businesses.

Most people think online security means simply protecting your credit card data from fraud and theft, but it actually goes way beyond that.

The potential for mayhem and just plain disruption of your life doesn't just mean credit card fraud - it can mean having your identity stolen, your life disrupted and spending hours cleaning up after an online 'vandalism' attack.

You must protect yourself from everyone from the teenage computer hacker to the organized crime syndicate using computer worms and keystroke logging viruses.

The great news is that a number of simple techniques should protect you against the vast majority of threats, since the evil doers will simply move on to easier pastures.

Update your anti-virus files

The widespread 'Bad Trans' worm logged keystrokes and transmitted potentially sensitive data such as credit card and social security numbers to the 'bad guys'.

Though this virus contained a high level of criminal intent, it was easily blocked by anyone with up-to-date anti-virus files.

If you don't have anti-virus software with current virus definitions installed, you leave the door wide open for security problems.

Install a 'Firewall'

A firewall helps prevent unauthorized access to your computer by 'hackers'.

It closes off the entry points (called open 'ports') carried by virtually every computer connected to the Internet.

A common misconception is that firewalls are only for people with cable or other high-speed connections.

Even if you use a dial up connection to get online, a firewall can help you detect and prevent people from logging on to your computer, stealing files or even using your computer to break into others!

You can take a free test of your computer's security by logging on to http://www.symantec.com/securitycheck/ and clicking 'Find out today if you are safe'. The results may surprise you.

Use secure sites

Only give sensitive data such as credit cards, social security numbers and important passwords over a secure connection.

This means the little yellow lock appears in the lower part of your browser and nobody but the website you are connected to should be able to read the data you send.

Change passwords often

An easy way for you to protect your sensitive data and email is to change your passwords on a monthly basis, or even more often depending on how frequently you use computers away from home.

If you log on to your email at the library, in 'cyber cafes' or any other remote computer then the possibility exists that computer could have a key-stroking virus present.

This means everything you type into the computer (passwords, birthdays, social security numbers, credit cards) could be logged and used by someone else.

** Change your passwords at lease once a month.

Though not fool-proof, these security tips should help reduce your vulnerability and keep you safer online.

Tips For Safer Computing Online

noreply@blogger.com (meor) — Fri, 04 May 2007 08:03:00 +0000

by: BB Lee

by BB Lee (C)2004

New computer viruses threaten the unwary user everyday. Hackers
jeopardize your online security with invasive computer techniques to
steal your passwords, personal information, even identity.

Unscrupulous marketers bait you with free software that unleashes
spyware, trojans, or worms, on your system.

While other marketers bombard you with popups at every turn. And
others send unsolicited spy emails asking you to click links to unsafe websites that install threating software on your computer, or try to download your private information.

These are only a few of the security issues involved while online.

Read through the following list to arm your computer and protect yourself against these vicious and often malicious online attacks.

1. Install a good anti-virus software.
Here's a good free anti-virus software...
Fr** AVG Anti-Virus......
New - AVG Fr** Edition is now available for all single home users
worldwide! More detailed information can be found in the AVG Free
Edition License Agreement.
Click Here To Download:
http://www.grisoft.com/us/us_dwnl_free.php

2. Install a personal firewall.
This personal firewall is one of the best online....
http://www.zonealarm.com

3. Install a good pop up blocker.
Google has a free pop up blocker so does Yahoo. The only drawback
is you will have to download and install their toolbar.

4. Know Privacy Policy.
Read the websites privacy policy before releasing personal information.
Note do they share or sell your information with third parties. If they do you might reconsider releasing your personal information.

5. Passwords.
Never use easy to guess passwords like your favorite color, your social security number, your birthdate, words less than six characters. Mix up passwords with combinations of numbers and symbols.

6.Virus Warnings.
Don't forward virus warnings you receive in emails. It's not your
job to warn others. And you might be circulating a fake warning
designed to scare receivers into downloading trojans or removing
important files on their computer.

7. Keep It Secret.
Don't give your password to anyone. Be wary of emails asking you to give out your personal passwords for accounts online. Or emails asking you to click a link and enter your password on the site. This site might be a fake sent by hackers "phishing" for victims.

8. Primary Email Address.
Don't divulge your primary email address on unfamiliar sites. You
might be bombarded with unsolicited emails by marketers who
sell your address to third parties online.

9. Free Accounts
Set up several free email accounts with a psuedo name to handle
spam, when you register with unfamiliar sites, or to use on chat and message boards.

10. Chat Line And Message Board Warnings.
Don't release personal information on chat lines or
message boards. This is one way many identity thefts occur.

Internet Scams 102 -- Hijackings and Spyware

noreply@blogger.com (meor) — Sun, 22 Apr 2007 03:51:00 +0000

by: Janette Blackwell

My friend Janice is afraid to go on the Internet because of the terrible things that might happen to her. She views a simple trip to get e-mail the way she views going alone, late at night, to a dangerous part of town.

Please . . . it’s not that bad. Though, come to think of it, it’s ALMOST that bad: hijackers can now do things to people who already have antivirus and anti-spyware programs. To people who have carefully NOT clicked on scam e-mails. Some hijackers can disable your firewall, your antivirus software, and your spyware killers. Or they can prevent antivirus and spyware from being updated.

But there are solutions. Here’s what you do:

HIJACKINGS

You know you’ve been hijacked if your start page is different and if you keep getting things you didn’t intend to get -- frequently pornographic sites and popup ads. You change things back the way they were, but they won’t stay changed.

These nasties nabbed you through a security hole in Microsoft Windows. If you haven’t been caught and don’t want to be, http://www.spywareinfo.com/articles/hijacked/prevent.php says,

“First and most simply, stop using Internet Explorer. If you use either Mozilla, Firefox or Opera, you are immune to virtually all browser hijackers.”

Actually, it’s not that simple. There are ways scammers can get around Firefox. Microsoft is also busy locking its barn doors, though I’m afraid the horse has already been stolen.

If you decide to stay with Internet Explorer, be sure to keep it up to date, especially with what they call “critical updates.”

PREVENTING ATTACKS

The most basic and most necessary protection, one you’ve probably installed already, is antivirus protection. The antivirus programs upgrade constantly to protect us from the latest viruses. Norton is the most common, and a good choice. If you prefer a simple, uncomplicated solution, go to the site that sells Norton, http://symantec.com/, and download all the antivirus protection you want.

If you’re a thorough person, however, one who wants to learn about all the options, go to http://antivirus.about.com/od/antivirussoftwarereviews/, and you will learn of problems and solutions you never dreamed existed.

WHAT YOU GET FOR NOTHING IS NOTHING -- OR WORSE

Unfortunately, an antivirus program alone is not enough these days. You need ANTI-SPYWARE.

Because the latest hijackers can disable anti-spyware -- AND keep you from downloading updates -- you want some that is really, really good. The techie who manages my website says, “Get something that can WARD OFF attacks, not just remove them after they’ve infected you. Once really vicious spyware is on your machine, it may be impossible for anyone but an expert to remove it.”

“But what about all the free anti-spyware?” you ask. If you go to http://www.apcug.net/Reports/Editorial/2004.htm, you’ll see under December 2004 an article “Beware of SCUMWARE Pretending to be Anti-Spyware” which tells one man’s experience. Sometimes what you get for nothing is nothing. Or worse than nothing.

When my computer ran slower and slower, some parts of my website disappeared, and question marks appeared all over my website homepage, I yelped for help. Should have yelped sooner, but better late than never. Asked my website manager what he uses. He uses Lavasoft’s PROFESSIONAL program of Ad-Aware and Ad-Watch. I bought it, and it found 17 pieces of spyware (Alexas and tracking cookies), plus a possible browser hijack attempt. (The techie said, “That’s nothing. They found 83 pieces of spyware on mine!” But then he’s a pro.) Ad-Aware removed all the problems except the question marks on my website home page, http://foodandfiction.com/Entrance.html. These are probably due to the attempted hijack. I’m stuck with them. Fortunately they don’t show on any computer except mine.

If you want to lead a simple life, come here to http://lavasoft.com and download their PROFESSIONAL type of Ad-Aware and Ad-Watch.

If you prefer an in-depth investigation of anti-spyware,
http://www.pcworld.com/reviews/article/0,aid,119572,00.asp can help you. They’ve tested most of the anti-spyware out there, though I must say that Ad-Aware’s pro version was not tested, only the pc version.

Just don’t wait until you’re in big trouble. Do something now!

IF YOU’VE BEEN HIJACKED

A good, basic article can be found by going to http://www.apcug.net/Reports/Editorial/2004.htm. Scroll down to September 2004 and download “Help! I’ve Been Hijacked . . .”

Another good article is, “How to Remove Adware and Spyware,” http://antivirus.about.com/od/securitytips/a/removespyware.htm.

You might also read “Invasion of the Browser Snatchers” at
http://www.pcworld.com/news/article/0,aid,84464,tk,dn021402X,00.asp. The article will explain how to undo the damage -- although some hijack damage can’t be removed that easily.

More Free Tools Increase Security For Your PC

=====================================

A recent article about preventing hackers from breaking
into your computer caused an overwhelming response by
readers.

It seems everyone has an opinion about the best software
and advice for keeping your computer safe from viruses and
online predators. The following will help you increase your
online security and usually without spending a dime!

Zone Alarm

Zone Alarm offers several versions of their
popular firewall software with various options for
increased security. The basic firewall software comes free
of charge and ranks among the most highly rated firewalls
available. The paid version helps you to eliminate
everything from pop-up windows to unwanted advertising and
also helps you track hackers back to their source.

Visit www.zonealarm.com to download your copy today,
especially if you don't already carry a firewall on your
system.

The Guru Of Security

Visit www.grc.com if you want a real "eye opener!" Frankly,
some of the things I saw on this website shocked me. I had
no idea so many potential problems existed for breaches in
your online security.

But what also shocked me was how simple most of the "fixes"
rate for securing your computer against attack. It became
very apparent to me that most computer hackers don't
exploit hardware or software weaknesses, they actually
exploit our ignorance about the simple steps we should take
to protect ourselves and others.

When you visit www.grc.com you'll see the site covers a lot
of ground. Since you might find it easy to get sidetracked
with all the interesting information, make sure to
specifically check out the "Shields Up!" area. This section
offers two comprehensive tests of your Internet connection
to check for the typical points of entry used by hackers.

The first test, "Test My Shields," checks the security of
your Internet connection itself and how much system and
personal information others can obtain without your
knowledge.

The second test, "Probe My Ports," attempts to find open
ports on your computer and evaluate how and where a hacker
could enter.

Both tests will help you spot the most common and obvious
vulnerabilities most of us face when connected to the
Internet. Also to its credit (and unlike similar sites),
this website doesn't use these tests as a lead-in to try to
sell you anything.

Free Anti-Virus Software

Visit www.grisoft.com to download a free anti-virus
software package that rivals anything you could buy. The
software comes with free updates on virus definitions
(critical for up-to-date protection) and will even certify
your outgoing email as virus free!

I have used this software myself and, though nothing rates
perfect, I have found it rivals products costing $50 or
more. If you don't carry virus protection software on your
computer, stop this minute and go to www.grisoft.com to
download the free version now.

With so many resources and advice available for free, no
valid excuse exists for not immediately securing your
computer against hackers, vandals, viruses and malicious
code.

3 Summer Computer Tips

noreply@blogger.com (meor) — Mon, 09 Apr 2007 03:12:00 +0000

by: Sharron Senter

#1 – Summer Computer Travel
Holiday travelers should be on alert when arriving home from long weekends, such as the Fourth of July, a popular time for computer viruses to spread.

Most computer users have a tendency to turn off their computers when away on trips, which means you’re not getting newly-released anti-virus patches or anti-spyware updates; the two most common areas that cause computers problems. We recommend you update anti-virus and anti-spyware scans before opening e-mail or going online after an extended absence.

We consistently see an increase in calls for virus related problems immediately following long weekends. Avoid the problems altogether by updating your security software before using your computer. For a free listing of viruses, spyware threats and trends, visit: www.VisitingGeeks.com/downloads.htm

#2 -- Should You Leave Your Computer Running?
One question we hear frequently is, "Should I leave my desktop computer on or turn it off?"

There are 2 schools of thought…
Turning it on and off numerous times during the day subjects the microcircuits to flexing and fatigue due to change in temperatures. Over time this could lead to a break in the circuitry and result in system failure.

Leaving the computer on all the time puts excess wear on the mechanical components (the hard drive spindle motor and cooling fans).

Best compromise. First user in the morning turns it on; last user turns it off.

We leave our desktops on all the time allowing for scheduled utility tasks to run during overnight hours. We also restart the systems (to flush the RAM and reset the operating system) on a regular basis and routinely remove the case covers to clean out any dust that may have accumulated, especially around the fans and screens.

#3 -- Stop Popups!
Never click inside the window of a popup. Instead, close it by clicking on the X in the upper right corner. Many people are fooled into installing spyware applications by popups that promise to clean their system. If you receive a message saying it can help, assume it’s spyware and don’t click!

How To Take Care Of Your Laptop Computer

noreply@blogger.com (meor) — Wed, 04 Apr 2007 05:34:00 +0000

by: Joe Chianese

As the proud owner of a laptop computer, you'll want to keep
your machine in the best possible condition.

Aside from cleaning your screen and dusting the keyboard,
however, you'll need to take a few extra steps to maintain
your laptop's health:

Play it cool

A laptop computer generates a lot of heat, especially when
running the latest high-powered software. Too much heat and
you risk damaging the internal circuitry.

Always try to keep your laptop in a well-ventilated, cool
environment. And ensure you don't block the fan grills on
the sides, back, or bottom of the machine at any time.

Handle the screen carefully

Avoid touching or playing with your LCD screen.

Yes, it might be fun to watch the waves generated by your
finger against the screen, but LCD displays are fragile
devices that must be cared for.

Take care when cleaning the screen too, and use only
approved cleaning materials.

You won't want to pay the money for screen repairs or, even
worse - a new machine entirely.

Don't drop it

Whatever you do, don't drop your laptop computer! Keep it
safe inside of a carrying case when moving around or
traveling.

Don't leave it on the edge of a table or on an unstable
support of some kind. One ill fated drop to the floor could
spell death for your mobile office.

Try to make sure the rubber feet underneath are in good
condition and are still attached. This will prevent the
device from sliding around accidentally.

Be careful with those drinks...

If you need to have a drink while working or playing, be
careful not to spill it.

Your laptop computer could suffer the consequences from just
a few drops of liquid poured in the right places.

While you probably do eat and drink around it regardless,
you will want to occasionally wipe down the edges, the
keyboard, the touchpad, and maybe even wipe down the screen
to keep any dirt from accumulating.

Just say no to viruses

Security wise, make sure you obtain an anti-virus program.

Secondly, keep it updated!

Buying an anti-virus one month and not updating it for the
next six really negates it purpose. Your laptop computer
could be exposed to hundreds and thousands of new viruses
every month if you don't update your virus definitions.

Most anti-virus programs have automatic update methods,
eliminating the need for you to have to remember to do it
manually.

Avoid Popups
Pop-ups are particularly annoying on a laptop computer.
Trying to close a bunch of windows without a regular mouse
can be a nuisance.

You'll want a pop-up blocker, such as the Google Toolbar
(located at http://tools.google.com), to prevent these pop-
up ads.

Many intrusive forms of advertising, and even some viruses,
can install software on your machine by using various forms
of pop-ups. It's best to get yourself a blocker and avoid
the situation entirely.

Use a firewall

Always utilize a firewall on your Internet or network-
enabled laptop computer. Even if you use Windows XP's built-
in firewall (or purchase one from such companies as Norton),
your security will greatly benefit from it.

Blocking out all the unnecessary ports and closing all the
loopholes will prevent a hacker or virus from freely
entering your hard drive.

So there you go. Combine all of the above tactics and help
your laptop enjoy a happier and healthier lifestyle!

Protection for your computer system - Painless and free !

noreply@blogger.com (meor) — Sun, 01 Apr 2007 07:20:00 +0000

by: John Roberts

Painless (and FREE) P.C. Protection

Viruses, Bugs, Worms, Dataminers, Spybots, and Trojan horses. The Internet is a veritable minefield of things that can invade your PC and affect it’s Security and Performance.
You can do something about it and you can do it FREE, using some or all of the following programs and tips.

Anti-Virus protection.
One of the best Free programs for this is AntiVir Personal Edition Anti-Virus software. Download it from:
http://www.free-av.com
Install on your PC and leave it running to block any incoming bugs or viruses! It can also be used to scan your system for any previous invasions, but be patient, this takes about 15 minutes to complete. Worth running periodically, to check all is ok.

FireWalls and Broadband.
If you are on Broadband, consider using Firewall software. Most good ISP’s now supply free. (eg AOL). If yours doesn’t, you can get a reasonably good Free personal firewall system from ‘ZoneAlarm’ at http://www.zonelabs.com .
Tip – DON’T leave your PC connected to the Internet when you are not using it! Reduce the chance of something loading while you are not monitoring things !

SpyBot finders and Ad blockers.
Various programs available on the web, both ‘Paid’ and ‘Free’. You can get good results from using 2 Free packages that are available. These are ‘SpyBot Search & Destroy’ and ‘Ad-Aware’. Downloads available at
http://www.lavasoft.de for AD-Aware
http://www.safer-networking.org for SpyBot
Using both of these packages ensures that, you get with one, any ‘bots’ that the other one misses.

Suspect you have a virus ?
If you think you already have a virus, a good Free tool for checking and killing them is McAfee Stinger. Free download at:
http://us.mcafee.com/virusInfo/default.asp?id=stinger

Some General Tips
Get in the habit of , every time you disconnect from the web, deleting ALL files from the following folders:
C:/WINDOWS/Cookies
C:/WINDOWS/Temporary Internet

Beware ‘Boys Toys’ and ‘Freebies’! Think, if someone wants to spread a bug, get tracking software onto your PC etc, the best place for them to do it is places where you go to get ‘freebies’ to download! The above sites are normally ‘ad free’, but be aware that if you download porn, free music, free games, free software, there is often a ‘price’ to pay. Always use the above programs after visiting ANY of these sorts of sites!

Basic Steps To Optimize Your Internet Security

noreply@blogger.com (meor) — Wed, 28 Mar 2007 00:23:00 +0000

by: Popescu Alexandru

After seeing many people complain about their weak Internet security I decided to write down some things that will help you for your Internet security.

First, here are some tips to make windows safer :

For basic security and update patches install Service Pack 2 for Windows XP or Service Pack 4 for Windows 2000.

Once a month use Windows Update so you can get the latest pacthes.

When you download software from the Internet make sure you download it from the original website.

Always run anti Trojan and anti virus software.

Even if you don't use it you have to make your Internet Explorer as safe as possible.

When you access the Internet you are browsing the web using a browser such as Internet Explorer.The Internet Explorer contains several security vulnerabilities. You should make it as safe as possible or switch your default browser to an alternative. You will have to set some options from the Manage Add-Ons in the Internet Options. You will see a list of add-ons that can be activated or deactivated. If you see any unusual entries just deactivate them so you can be sure you don't have a trojan/worm.

Under Internet Options -> Security -> Internet -> you will see the Edit Level.You should set it to high in order to disable most of the security threats.

Your Web Browser should be ok now. Let's see what we have to do from our email point of view.

Because it's built-in in their Windows system lots of users like to use Outlook Express for emailing. But it's a fact that it contains many security vulnerabilities so I advise you to use alternatives. If you use a web based Email (you can browse your email with your web browser) you can delete viruses even if you don't download them to your PC.

Make sure you have installed an Anti Virus for 100% virus protection. One that I've found to be very good and never disappointed me is the AVG Anti virus. If you take the time to regularly update it you will be safe enough with it.

Lots of people install Firewalls because they belive their Internet security will be higher. I personaly disagree. If you do not know how to best configure it, and you have to know much about the tech behind it to do so, it will just make your PC slow and software not working.You can just use the Windows XP SP2 firewall for basic security.

All this tips should make your PC safer. I browse the Internet every single day for some time now and they worked great for me. I haven't met a virus/worm for some time now.

noreply@blogger.com (meor) — Sun, 25 Mar 2007 03:43:00 +0000

by: Niall Roche

The explosive growth of the Internet has meant that thousands of people are today experiencing the joys of being online for the first time. With growth there always comes pain. Be it your growing pains as a child or the growth and development of this part of our culture called the Internet.

Firstly we need to quickly explain what the Internet is and where it came from. The Internet is the offspring of a military project called Arpanet. Arpanet was designed to provide reliable communication during global nuclear war. A vast network of interconnected computers was set up all over the world to allow the various branches of US and NATO forces to communicate with each other.

Nuclear war never came (thankfully) and the world was left with a massive network of computers all connected together with nothing to do. Colleges and universities started to use these computers for sharing research internationally. From there it grew and spread outside colleges to local homes and businesses. The World Wide Web was born and its father was a guy called Tim Berners Lee.

When you're connected to the Internet you're sharing a vast network with hundreds of millions of other users. This shared network provides resources that 15 years ago were never thought possible. Unfortunately when something is shared its open to abuse. On the Internet this abuse comes from hackers and virus creators. Their sole intent is to cause chaos and/or harm to your computer system and millions of other computer systems all over the world.

How do you combat this? You need an Internet security system. This might sound complicated but your Internet security system will be quite straigtforward being comprised of just 2 - 3 Internet security products. We'll look at each of these products in more detail now:

AntiVirus Software

The first and most critical element of your Internet security system is antivirus software. If you don't have up-to-date antivirus software on your PC you're asking for trouble. 300 new viruses appear each month and if you're not constantly protecting your system against this threat your computer will become infected with at least one virus - it's only a matter of time.

Antivirus software scans your PC for signatures of a virus. A virus signature is the unique part of that virus. It can be a a file name, how the virus behaves or the size of the virus file itself. Good antivirus software will find viruses that haven't yet infected your PC and eliminate the ones that have.

Antivirus software can only protect your computer from viruses trying to infect it via email, CD-Rom, floppy disk, Word documents or other types of computer files. Antivirus software alone will not keep your computer 100% safe. You also need to use firewall software.

Firewall Software

The use of firewall software by home computer users is a relatively new occurence. All Internet connections are a two way process. Data must be sent and received by your computer. This data is sent through something called ports. These are not physical things rather aspects of the way your computer communicates online.

Firewall software watches these ports to make sure that only safe communication is happening between your computer and other computers online. If it sees something dangerous happening it blocks that port on your computer to make sure your computer stays safe from the person who is trying to hack into your system.

An easier way to understand a firewall would be to picture your computer as an apartment complex. At the front door of this complex there is a security guard. Every person who enters the complex must pass this security guard. If the security guard recognizes the person entering as a resident he allows them to pass without saying anything. If, however, the person entering the complex is unknown to him then he will stop that person and ask for identification. If they have no business being at the apartment complex he escorts them from the building.

If you are not currently using firewall software your computer will get hacked into - that's a guarantee.

PopUP Blocker

You can get a good popup blocker at no cost. An easy way to do this is to install either the Google or Yahoo toolbar. Both of these come with popup blockers built in. Popups are not necessarily dangerous but are a nuisance and using either of these toolbars will make your life that bit easier.

A simple rule for practicing online security is: "If in doubt then don't". If you don't recognize the file, the email address, the website or if your gut feeling says "no" then don't click that button.

Do The Media Spread Computer Viruses?

noreply@blogger.com (meor) — Sat, 24 Mar 2007 01:24:00 +0000

by: Joel Walsh

Summary: Could the mass media hype about computer viruses actually make the problem worse?

If you believe what you hear in the media, there are an awful lot of viruses going around. No, I'm not talking about the make-you-sick kind of virus, though they get plenty of airtime, too. I'm talking about the kind of virus that enters via your internet connection rather than your nasal passages.

What the mainstream media often don't tell you--at least, in most radio and television newscasts and in the crucial headlines and opening paragraphs of newspaper articles-- is that many of these "viruses" are not viruses at all.

What Computer Viruses Really Are

The main reason the mainstream media always are in alarm over viruses is that they tend to call any malicious computer program a virus. In reality, there are at least eleven distinct types of malicious software, or malware, commonly affecting computers today. The most common of these are worms, Trojans, and spyware.

So, what's the difference between computer viruses and the other types of malware? The difference is that computer viruses are just about the only ones that regularly shut down computers and cause other obvious damage. The most common of the other kinds of malware--worms, Trojans, and spyware--are usually only detectable with a special scan.

The Real Danger of Computer Viruses

If the other types of malware are so unobtrusive that they can only be detected with a special scan, then what's to worry about? For starters, these programs are called malicious for a reason: they are designed to cause some kind of damage, if not to your computer, then to someone else's.

Worms are most famously used to damage, destroy, or disrupt other computer networks than the one on which the host computer is located. For instance, worms have been used by website owners to shut down rival websites by sending overwhelming numbers of requests to the computer that hosts that website. Worms have also been used to send out viruses to other computers, often without infecting the host machine--after all, what would it benefit the worm to shut down its host computer?

Trojans, in turn, are often used to insert worms and other malware on your computer, even if the Trojan itself does no damage.

But even if you don't care what happens to anyone else, you should still be concerned about one kind of malware: spyware, a kind of malware that, true to its name, collects data from your computer and sends it back to a remote host.

Most spyware is only interested in monitoring your internet usage so it can tell other programs, called adware, what advertising to popup on your computer. However, there are criminal spyware programs that steal financial data, or perform a thorough identity theft. Don't think you have personal or financial data on your computer? Some spyware programs contain a keylogger, which is a program that copies whatever you type, usually in order to snatch passwords. Even if you keep no financial information on your computer, if you ever buy anything over the web, the keylogger would allow its owner to buy stuff using the same information you typed in to buy stuff yourself.

Why Blame the Media?

Given the danger of all these different types of malware, isn't it a good thing that the mass media are becoming hysterical about it? And can't they be forgiven the sloppy reporting of calling Trojans, worms, spyware, and other malware "viruses"?

No, no, no.

This is a classic case of bad reporting doing more damage than no reporting at all. In this case, the damage bad reporting has done is to promote a common myth that goes something like this: "The only malicious software is a virus. Viruses damage your computer. Therefore, if my computer is working OK, my computer has no malicious software. I only need to scan my computer for problems when there is a sign of problems."

Thanks to this myth, many people complacently let their antivirus software go months out of date, not wanting to be bothered with scheduling an automatic update. Just as bad, many people don't have any extra software to combat the other types of malware that may not be covered by antivirus software.

In fact, it's not uncommon for people who have found malware on their computers after a scan to say, "but I never had malware on my computer before!" But how would they have known if they had never scanned!

Until the biggest mainstream media--and especially television--start educating the public about the need to have their computers automatically scanned at least daily, the world will continue to have major, drawn-out problems with malware that could have been wiped out as soon as soon as the anti-malware software makers discovered it.

And until that day, the mainstream media will have many more opportunities to run hysterical stories about "viruses," thereby forcing them to sell more newspapers and broadcast to even larger audiences of people who suck at the information trough yet somehow never become full.

Is Your Computer Sick?

noreply@blogger.com (meor) — Thu, 22 Mar 2007 02:25:00 +0000

Viruses and spyware usually show up on your computer one of two ways.

Either they invade your system with a frontal assault like
the Huns attacking the Romans, or they sneak in a back door
like a cat burglar.

Either way, once a virus or piece of spyware gets on your
system, getting it off can rate harder than curing a severe
case of trench foot!

Viruses, malicious programs designed to disrupt normal
computing, and spyware, programs intended to literally "spy"
on your activities, can enter your computer a number of
ways.

Most commonly they enter your system through an email attachment, by sharing files with an infected computer by disk, as a "ride along" with a 3rd party program you install, or through a "back door" port in your computer.

Regardless of how they get on your system, once in place,
they cause no end of headaches and frustration.

The following represent typical signs you may suffer from
infection by a virus or piece of spyware.

Your computer starts acting oddly by doing things it never
did previously.

Your modem starts trying to dial out to the Internet without
you initiating a surfing session.

You notice that files start disappearing, the system stalls,
runs slowly, or even crashes frequently.

Your computer takes progressively longer to boot up every
time you start it or you notice that your available hard
drive space has disappeared. Strange popup windows appear,
even when you're not surfing the web, or you delete a
program and it "magically" reappears next time you boot the
system.

If you suspect you a virus or a piece of spyware has invaded your computer, follow these steps to first identify and then delete the offending code:

Step 1 - Back up your important files, but remember to scan
these files for viruses before reinstalling to avoid
accidentally re-infecting your system.

Step 2 - Update your anti-virus definitions and perform a
scan of your hard drive.

If you don't carry virus protection, or you suspect your
anti-virus software got corrupted somehow, then log on to
www.pandasoftware.com and use the free Panda Active Scan
service to check your hard drive for viruses.

Follow the instructions for quarantining and removing the
offending files.

Step 3 - Scan your hard drive with an adware, scumware, or
spyware detection and removal tool like Adaware
www.lavasoft.de/support/download/ or Spybot
http://spybot.safer-networking.de/.

Step 4 - In many cases, when the virus or spyware program
gets installed with a free utility or game you download from
the Web, you must usually uninstall the utility or game to
finally get rid of the problem once and for all.

Step 5 - Avoid re-infection by keeping your anti-virus and
firewall up-to-date at all times.

As a last resort, if you run into a program you simply can't
get rid of, but can figure out the offending file's name, do
a search for the file name on Google.com. Often you will
find you're not the first victim and may get valuable advice
for cleaning up your system.

However, be very careful of the information you find and
think twice before modifying any system files.

Does Your PC Have Worms?

noreply@blogger.com (meor) — Wed, 21 Mar 2007 03:47:00 +0000

by: Joel Walsh

Worms aren't just for dogs anymore. Find out how to inoculate your computer against these nasty parasites.

What Are Worms?

Worms are descended from viruses and are even nastier. Just as ever stronger doses of pesticide breed ever more resilient locusts, better and better anti-spyware software bred ever more devious viruses.

Finally, some virus designers stopped having their creations infect and take over files the way real viruses infect and take over cells. Instead, they created programs that could stand on their own and cause plenty of trouble without the help of any other software applications. Just worms are independent organisms that can infect a host directly, so do computer worms infect computers directly.

What Do Worms Do?

Worm designers are often even more sinister than virus designers, since worm designers are not just vandals. Worm designers often use their creations to achieve specific goals:

• Backdoor creation. Worms often try to set up another kind of malware, a backdoor. A backdoor is a hidden opening in your network connection that lets the worm send data out and take data in. Practically speaking, the data it's sending out are often spam emails, and the data it takes in are instructions on spam emails to send.

• Denial of service attack. Some worm designers really are vandals rather than profit-hungry con artists sending spam. But their vandalism can be more targeted. They use worms to send out numerous requests to remote computers, such as web servers, in order to overwhelm them and therefore shut them down. This is called a denial of service attack.

• Spyware, Trojan, adware, and virus installation. Worms are often used simply to unleash other forms of malware on a computer that might otherwise block them.

• Information theft and fraud.Worms can multitask in order to set up spyware that gathers sensitive information--often financial information--and then set up backdoors, Trojans, viruses, or dialers to disseminate the stolen data.

How Do Worms End Up on a PC?

Worms enter PCs just as viruses, spyware and other malware do: any way they can! Some favorite points of entry for worms:

• Websites can actually download software to your computer without you realizing it. This software includes not only worms, but also spyware, adware, viruses, and other malware. These malware programs find their way into websites either by the deliberate design of the site owner or because hackers have installed the software on the website's server.

• Peer-to-peer file-sharing networkscontain many nice-enough-looking files that are really worms. One of the sneakiest disguises is a filename that indicates the spyware is really a video of a beautiful actress.

• Email, the favored route of viruses, can still be exploited by Spyware. But since new email programs usually block the automatic opening of file attachments, this is less of a problem than it used to be.

• Any internet connection inevitably lets data flow both in and out, and so is vulnerable to attacks by worms.

How Do You Get Rid of Worms?

There's really only one good way to make sure your computer is rid of worms: scan it with multiple antivirus and anti-spyware programs using a full-system scan. Worms are tricky, so anything less than a full-system scan might let them escape. Worse, with new worms coming out all the time, some antivirus and anti-spyware packages may not even know about a new worm until after its wreaking havoc on your machine. That's why you should try using more than one antivirus program and more than one anti-spyware program to increase your odds of successfully detecting the malware.

Don't have more than one anti-spyware and antivirus software? You'd better start downloading. After all, worms won't take excuses.

e. Adware

10. Which of the following is most likely to steal your identity?
a. Trojan
b. Worm
c. Virus
d. Spyware
e. Adware

Answers:

1. c. virus. Trojans, worms, spyware, and adware all depend on your computer staying up and running. They use your computer's resources to accomplish whatever their designer intended, such as sending emails, displaying advertising, or stealing information from your computer. Viruses, however, are usually created by vandals who just want to damage as many computers as possible.

2. c. virus. Viruses are not stand-alone programs. Just as biological viruses must take over the cells of their host in order to function and reproduce; computer viruses must take over one or more files of the computer on which they are stored. Trojans, worms, spyware, and adware are all stand-alone programs that can run without the help of another application, though they often come bundled with other applications as a decoy, or with other malware.

3. b. worm. Worms are stand-alone programs that are often used to send spam emails, or emails containing viruses. Trojans often contain worms which are then installed for the purpose of sending spam emails, but the worms are what actually send the emails.

4. e. adware. In the strictest sense, adware is rarely patently illegal or destructive, and so antivirus software makers have traditionally avoided treating it as malware. Adware designers are usually large advertising companies with hundreds of millions of dollars, and they take care to insert end-user licensing agreements (EULA) that supposedly mean that the software is installed with permission. Also, adware will not usually do anything more destructive than show advertising. Nonetheless, adware can quickly multiply on a computer, hogging system resources and causing a computer to slow down or even malfunction. That's why most anti-spyware software makers target adware as well.

5. a. Trojan. By definition, Trojans bear other malware within them, just as the mythical wooden worse bore Greek warriors. The malware can be viruses, worms, spyware, or adware.

6. e. adware, though d. spyware, is also correct. Kazaa's developers, Sharman Networks, make most of their money from the advertising shown by the included adware. The adware typically runs even when the Kazaa software is not in use. Sharman Networks has adamantly denied that the adware that comes with Kazaa is spyware, since, like most adware, it comes with an end-user license agreement that says the user grants permission for the software to be installed. In reality, few Kazaa users, until recently, were aware of just how much adware was being installed on their machines (as much as a dozen or more). Plus, the adware does monitor your internet usage, and so is spyware in the strictest sense.

7. b. worm. Worms most commonly install a "backdoor" internet connection in order to send out data (for instance, spam emails or requests to remote servers) undetected.

8. b. worm. Worms, which most commonly install a "backdoor" internet connection on the host computer, are perfect for sending out the millions of server requests needed to achieve a denial-of-service attack. A denial-of-service attack is when a server is maliciously sent so many hits that it is overwhelmed and cannot continue to operate.

9. a. Trojan. The Trojan "Magic Lantern" was famously used to install monitoring software on the computer of a suspect who was later brought to trial partly on the strength of the evidence gathered.

10. e. Spyware. Spyware is malware that collects information from your computer and sends it to another remote machine, so by definition any software that steals your identity is spyware. However, spyware is often installed on your computer by a Trojan, or sent to you by another computer infected with a worm, so other kinds of malware pose an indirect threat of identity theft as well.

Different Types of Computer Infection!

noreply@blogger.com (meor) — Mon, 19 Mar 2007 05:47:00 +0000

When you listen to the news, you hear about many different forms of electronic infection. The most common are:

Viruses - A virus is a small piece of software that piggybacks on real programs. For example, a virus might attach itself to a program such as a spreadsheet program. Each time the spreadsheet program runs, the virus runs, too, and it has the chance to reproduce (by attaching to other programs) or wreak havoc.

E-mail viruses - An e-mail virus moves around in e-mail messages, and usually replicates itself by automatically mailing itself to dozens of people in the victim's e-mail address book.

Worms - A worm is a small piece of software that uses computer networks and security holes to replicate itself. A copy of the worm scans the network for another machine that has a specific security hole. It copies itself to the new machine using the security hole, and then starts replicating from there, as well.

Trojan horses - A Trojan horse is simply a computer program. The program claims to do one thing (it may claim to be a game) but instead does damage when you run it (it may erase your hard disk). Trojan horses have no way to replicate automatically.

Why Do I Need Anti Virus Software For My PC?

noreply@blogger.com (meor) — Sun, 18 Mar 2007 04:23:00 +0000

by: Angie Noack

If you’ve recently purchased a computer, or are just learning about using email and the internet, you may have heard about computer viruses and anti-virus software. You may be wondering if this is something that you should be concerned about, and if so, what you should do about it. This article will attempt to answer these questions for you.

First, you may be wondering just what a computer virus is. Basically a computer virus is one of many types of small programs that install themselves on your computer without your consent. Usually they enter your program through an email, or while you are browsing a website.

When these programs run, usually without you knowing, they can cause all types of problems with your computer. Some viruses can be mildly annoying, slowing down your computer as they use your computer’s resources for another purpose. Others can be very dangerous, collecting your personal information and sending it to another party, or damaging your hard-drive.

True to their name, viruses are able to use your internet connection and email program and send themselves to the computers of other people you know, spreading themselves just like a contagious disease.

Because of this, just like the health of your body, when it comes to computer viruses, an ounce of prevention is worth a pound of cure. It is much easier to prevent viruses from entering your computer than it is to get rid of them and cure your computer once it becomes infected. This is why Anti-Virus software is important.

Once you realize that you need anti-virus software installed and running on your computer, you’ll have to choose which one to purchase and install. This can be a complicated process, but here are some tips to make it a bit easier.

First, check your computer to see if it came with anti-virus software. Many new computers are shipped with anti-virus programs already to go on them, you just need to turn them on. Check your instruction manual to see if this is the case with your computer.

Check with the vendor. If you purchased your computer from a local retailer, check with them to see what anti-virus program they recommend. They should be more than willing to help you and may even be able to provide you with a discount since you purchased a computer from them.

Once you have your anti-virus installed and running on your computer, be sure to contact the software’s support if you have any questions. It is also important to keep your software updated. Many of these programs will automatically update themselves when you are online. This is very important since new viruses are always appearing and you want to make sure your computer is protected.

by: John Lenaghan

The day you learn your computer is infected with a virus or spyware is a lonely yet aggravating day. You’ll be angry that you fell victim, and may feel helpless because of your lack of knowledge about virus removal or pc repair. But don’t worry - you’re not alone! Unfortunately, you’re actually part of a club of tens of thousands of people who feel the same way every day!

According to AVG, virus protection usually doesn’t detect adware or spyware both of which can wreak havoc on a computer. Thousands of people each day are infected with malicious programs! Worry no longer and stop feeling helpless because this guide is a basic computer virus repair guide that will help you identify and remove viruses and malware.

Are You Running Antivirus Software?

If you already have virus software perform an update for the latest version and then run a system scan. If you do not have such software, download a free copy of AVG virus protection at http://www.grisoft.com/doc/40/lng/us/tpl/tpl01. This will give you free real time virus protection, email scanning and virus removal tools.

Next, download and run Ad-Aware to remove spyware, adware, and other troublesome programs http://www.lavasoftusa.com/software/adaware/. Then download SpyBot Search & Destroy http://www.safer-networking.org/en/download/index.html. By using Ad-Aware and SpyBot you will have excellent protection against files that are often missed by virus protection.

To check for and eliminate browser hijackers, download and run CWShredder at http://www.intermute.com/spysubtract/cwshredder_download.html.

With the above programs simply run a scan and follow the prompts to remove any infected files or unwanted programs. Once that is done, upgrade your operating system, or download any needed patches, then reboot your computer.

These steps won’t solve every problem, but they will fix a large percentage of the things that cause your computer to act up.

9 Steps to Protect your MS Windows System from Viruses

noreply@blogger.com (meor) — Thu, 15 Mar 2007 05:04:00 +0000

by: Evgeny Kovalenko

Nowadays as the Internet and other networks are greatly developed computer viruses are distributed rapidly and intensively. Everyday several new viruses capable to damage considerably your computer system arise. Anti-virus specialists work hardly to make updates their software against new viruses as soon as possible. The viruses can get inside computer in different ways. That is why there is no simple method to protect system. Only series of measures can give you reliable protection from the infection. Below are 9 steps to protect MS Windows based PC system from viruses.

1. Make regular backups.

It should be said that there is no absolutely safe way of protection. Virus creators regularly find holes in new computer products to use them for infection of computer systems. Some dangerous viruses can considerably damage data files or even erase entire file system. Make regular backups of your data files to separate file storage device. It can be separate hard drive, flash card, compact disc or another file storage device which you choose. To ease the procedure you can use some automatic backup software. And be ready if the system will die because of virus infection.

2. Be ready to reinstall your system if it dies because of viruses.

Get distributives of your operation system and distributives of software which you use and keep them together, for instance, on a set of CDs not far away from you. In this case if virus infection will cause unrecoverable system failure you can rapidly reinstall your working medium.

3. Protect your network connection with Firewall.

Firewall is a software which blocks suspicious potentially dangerous connections to preventing viruses from network to penetrate into your system. Windows XP system has quit simple but reliable built-in firewall. You can enable it as follows. 1) in Control Panel, double-click Networking and Internet Connections, and then click Network Connections. 2) Right-click the connection on which you would like to enable firewall, and then click Properties. 3) On the Advanced tab, check the option to Protect my computer and network.

If you need more flexible control of connections with network you can get and install more advanced firewall software like Norton Personal Firewall or Outpost Firewall. If you use this software you have ability to permit or to block particular connections and to monitor network activity.

4. Use antivirus software.

Install antivirus software which will scan your system searching and erasing viruses on a regular basis. Leaders in antivirus software products for Windows systems are Norton Antivirus, McAfee, Kaspersky Anti-Virus and PC-cilin.

5. Regularly update operating system.

Windows XP has built-in automatic update service. It regularly contacts Microsoft server to find updates and notifies you if updates are ready to be installed. Updates are important because hackers regularly find holes in operating system which are often used by virus creators.

6. Don't install and don't run suspicious software.

Check new programs which you are going to install with anti-virus software. Don't download software from suspicious websites. To download software always seek website of software creator or official distributor. Do not open applications received by email from unknown persons.

7. Limit access to your computer.

Protect enter to system with password.

8. If you use Internet Explorer, consider moving to another browser.

As IE is the most distributed browser today virus creators actively use defects in its security system to infect computers. Infection may arise if you will visit webpage which contains invisible harmful code. You are more safe if you use less known browser only because virus creators do not pay much attention to it. Major IE competitors Firefox and Opera browsers provide now the same comfortable interface and range of services for working on the Web.

9. Use spam protection.

Viruses are often distributed via email. Switch on spam filters in your email box to block spam receiving. If you need assistance with using of the filters you can ask your email service provider.

All About Computer Viruses
by Kara Glover
kara333@earthlink.net

Your computer is as slow as molasses. Your mouse freezes every 15 minutes, and that Microsoft Word program just won’t seem to open.

You might have a virus.

Just what exactly is a virus? What kind is in your computer? How did it get there? How is it spreading and wreaking such havoc? And why is it bothering with your computer anyway?

Viruses are pieces of programming code that make copies of themselves, or replicate, inside your computer without asking your explicit written permission to do so. Forget getting your permission down on paper. Viruses don’t bother to seek your permission at all! Very invasive.

In comparison, there are pieces of code that might replicate inside your computer, say something your IT guy thinks you need. But the code spreads, perhaps throughout your office network, with your consent (or at least your IT guy’s consent). These types of replicating code are called agents, said Jimmy Kuo, a research fellow with McAfee AVERT, a research arm of anti-virus software-maker McAfee Inc.

In this article, though, we’re not talking about the good guys, or the agents. We’ll be talking about the bad guys, the viruses.

A long, long time ago in computer years, like five, most viruses were comprised of a similar breed. They entered your computer perhaps through an email attachment or a floppy disk (remember those?). Then they attached themselves to one of your files, say your Microsoft Word program.

When you opened your Microsoft Word program, the virus replicated and attached itself to other files. These could be other random files on your hard drive, the files furthest away from your Microsoft Word program, or other files, depending on how the virus writer wanted the virus to behave.

This virus code could contain hundreds or thousands of instructions. When it replicates it inserts those instructions, into the files it infects, said Carey Nachenberg, Chief Architect at Symantec Research Labs, an arm of anti-virus software-maker Symantec. Corp.

Because so many other types of viruses exist now, the kind just described is called a classic virus. Classic viruses still exist but they’re not quite as prevalent as they used to be. (Perhaps we could put classic viruses on the shelf with Hemingway and Dickens.)

These days, in the modern era, viruses are known to spread through vulnerabilities in web browsers, files shared over the internet, emails themselves, and computer networks.

As far as web browsers are concerned, Microsoft’s Internet Explorer takes most of the heat for spreading viruses because it’s used by more people for web surfing than any other browser.

Nevertheless, “Any web browser potentially has vulnerabilities,” Nachenberg said.

For instance, let’s say you go to a website in IE you have every reason to think is safe, Nachenberg said.

But unfortunately it isn’t. It has virus code hidden in its background that IE isn’t protecting you from. While you’re looking at the site, the virus is downloaded onto your computer, he said. That’s one way of catching a nasty virus.

During the past two years, another prevalent way to catch a virus has been through downloads computer users share with one another, mostly on music sharing sites, Kuo said. On Limewire or Kazaa, for instance, teenagers or other music enthusiasts might think they’re downloading that latest Justin Timberlake song, when in reality they’re downloading a virus straight into their computer. It’s easy for a virus writer to put a download with a virus on one of these sites because everyone’s sharing with everyone else anyway.

Here’s one you might not have thought of. If you use Outlook or Outlook Express to send and receive email, do you have a preview pane below your list of emails that shows the contents of the email you have highlighted? If so, you may be putting yourself at risk.

Some viruses, though a small percentage according to Nachenberg, are inserted straight into emails themselves.

Forget opening the attachment. All you have to do is view the email to potentially get a virus, Kuo added. For instance, have you ever opened or viewed an email that states it’s “loading”? Well, once everything is “loaded,” a virus in the email might just load onto your computer.

So if I were you, I’d click on View on the toolbar in your Outlook or Outlook Express and close the preview pane. (You have to click on View and then Layout in Outlook Express.)

On a network at work? You could get a virus that way. Worms are viruses that come into your computer via networks, Kuo said. They travel from machine to machine and, unlike, the classic viruses, they attack the machine itself rather than individual files.

Worms sit in your working memory, or RAM, Nachenberg said.

OK, so we’ve talked about how the viruses get into a computer. How do they cause so much damage once they’re there?

Let’s say you’ve caught a classic virus, one that replicates and attacks various files on your computer. Let’s go back to the example of the virus that initially infects your Microsoft Word program.

Well, it might eventually cause that program to crash, Nachenberg said. It also might cause damage to your computer as it looks for new targets to infect.
This process of infecting targets and looking for new ones could eventually use up your computer’s ability to function, he said.

Often the destruction a virus causes is pegged to a certain event or date and time, called a trigger. For instance, a virus could be programmed to lay dormant until January 28. When that date rolls around, though, it may be programmed to do something as innocuous but annoying as splash popups on your screen, or something as severe as reformat your computer’s hard drive, Nachenberg said.

There are other potential reasons, though, for a virus to cause your computer to be acting slow or in weird ways. And that leads us to a new segment – the reason virus writers would want to waste their time creating viruses in the first place.

The majority of viruses are still written by teenagers looking for some notoriety, Nachenberg said. But a growing segment of the virus-writing population has other intentions in mind.

For these other intentions, we first need to explain the “backdoor” concept.

The sole purpose of some viruses is to create a vulnerability in your computer. Once it creates this hole of sorts, or backdoor, it signals home to mama or dada virus writer (kind of like in E.T.). Once the virus writer receives the signal, they can use and abuse your computer to their own likings.

Trojans are sometimes used to open backdoors. In fact that is usually their sole purpose, Kuo said.

Trojans are pieces of code you might download onto your computer, say, from a newsgroup. As in the Trojan War they are named after, they are usually disguised as innocuous pieces of code. But Trojans aren’t considered viruses because they don’t replicate.

Now back to the real viruses. Let’s say we have Joe Shmo virus writer. He sends out a virus that ends up infecting a thousand machines. But he doesn’t want the feds on his case. So he instructs the viruses on the various machines to send their signals, not of course to his computer, but to a place that can’t be traced. Hotmail email happens to be an example of one such place, Kuo said.

OK, so the virus writers now control these computers. What will they use them for?
One use is to send spam. Once that backdoor is open, they bounce spam off of those computers and send it to other machines, Nachenberg said.

That’s right. Some spam you have in your email right now may have been originally sent to other innocent computers before it came to yours so that it could remain in disguise. If the authorities could track down the original senders of spam, they could crack down on spam itself. Spam senders don’t want that.

Ever heard of phishing emails? Those are the ones that purport to be from your internet service provider or bank. They typically request some information from you, like your credit card number. The problem is, they’re NOT from your internet service provider or your bank. They’re from evil people after your credit card number! Well, these emails are often sent the same way spam is sent, by sending them via innocent computers.

Of course makers of anti-virus software use a variety of methods to combat the onslaught of viruses. Norton, for instance, uses signature scanning, Nachenberg said.

Signature scanning is similar to the process of looking for DNA fingerprints, he said. Norton examines programming code to find what viruses are made of. It adds those bad instructions it finds to its large database of other bad code. Then it uses this vast database to seek out and match the code in it with similar code in your computer. When it finds such virus code, it lets you know!

Malware And Antivirus Software

noreply@blogger.com (meor) — Tue, 13 Mar 2007 14:23:00 +0000

by: Joel Walsh

Warning: most antivirus programs will not protect you against all forms of malignant software (often called "malware") on their own. Find out how to protect yourself.

Sure, your antivirus software will protect you against viruses. It will probably even do a good job against worms. But what Trojans, exploits, backdoors, spyware and the dozen other nasty software parasites?

Malware and Antivirus Software: a History

The war on computer viruses has led to an arms race between the designers of antivirus software and the designers of viruses (you didn't think viruses just created themselves did you?). Some years ago, virus designers responded to ever more successful antivirus software by creating the descendents of viruses, worms, which did not infect files but rather installed themselves directly on the hard drive, making them harder to detect.

The arms race has since led to a total of at least eleven distinct types of what is now called malware, a neologism meaning bad (as in malignant rather than shoddy) software. According to Wikipedia, these eleven types of malware are:

1. Virus
2. Worm
3. Wabbit
4. Trojan
5. Backdoor
6. Spyware
7. Exploit
8. Rootkit
9. Key Logger
10. Dialer
11. URL injection

There's a twelfth kind of malware: adware, which Wikipedia considers simply to be a subset of spyware.

Why Antivirus Software Isn't Enough for Malware

As you can see, makers of antivirus software have their work cut out for them if they're going to keep every instance of malware off your system. As a result, antivirus software makers have often had to pick their battles. Adware, whose makers often claim they are doing nothing illegal or even questionable, often gets treated more lightly.

Even when antivirus software makers do come out with a product that fights all twelve or so kinds of malware, responding to each new instance of malware to come on the market isn't easy. First the malware has to be identified, which means someone's computer, and probably tens of thousands of computers, will be infected first. Then, the malware has to be dissected. Then a removal program and a filter must both be written. Then the removal program and filter must be tested to make sure they work, and that they don't interfere with any other functions of the antivirus software or the computer itself. When a fix for the virus is out, it then has to be loaded into an antivirus software update and transmitted to every single computer worldwide that has the antivirus software installed.

The speed with which antivirus software makers are able to deliver updates for newly discovered malware would impress even Santa Claus. Yet there's still a crucial window of one to a few days between when the new malware has reached a critical mass of thousands of computers, and when the update is released. If your antivirus software is not set to check for updates automatically every hour or so, that window opens even wider.

Practically speaking, then, you're better off having more than one line of defense against malware. Even if two different anti-malware programs utilize the exact same database, there might be a crucial difference in the speed of getting updates. It makes sense to back up your antivirus software with anti-spyware software. When you consider that dedicated anti-spyware software developers make protection against the non-virus forms of malware their stock-in-trade, you can see why anti-spyware software is so essential. In fact, you should strongly consider having two anti-spyware programs running on your computer at all times, since the gap in updates between two anti-spyware programs can be even longer than for two antivirus programs.

After all, with a dozen kinds of malware out there, shouldn't you at least have two pieces of software to fight them?

Virus Prevention and Removal

noreply@blogger.com (meor) — Tue, 13 Mar 2007 14:18:00 +0000

by: Ashish Jain

A virus is a piece of code that gets loaded onto your computer without your knowledge and runs against your wishes. The first known occurrence of viruses goes back to 1987 when the ARPANET was infected by one.

One common misnomer among people is that you can infect your computer just by opening an email and reading its text. That is not possible; it is usually the files attached to the email that contain the virus. The most common file types are ".SCR" ".VBS" ", ".PIF"

Prevention is better than a cure: Here are some tips to make sure that your computer does not get infected.

* Get a good Anti-Virus software like Norton Anti-Virus, MacAfee, PC Cillin etc.
* Keep your anti virus software updated by downloading new virus definitions regularly. Most Anti-Virus software comes with the feature of updating virus definitions.
* Keep your windows operating system updated by regularly downloading new updates from the Internet. Windows O/S's have a lot of security loopholes and bugs that can be easily exploited by worms and viruses.
* Make sure the anti virus scans the file each time before its opened.
* Floppy disks and removable media are a good source of viruses; always scan them before accessing files on them.
* Never open email attachments from sources that are unknown or suspicious.
* Do not open emails that have questionable subject lines.
* When in doubt about a file, don't open it.
* Even with the best of precautions bad things can still happen. Backup all your data and important files.

Even after taking all these precautions if your computer does get infected, then here are a few things that you can do:

Online clearing tools - are a good source of trying to clean out the virus, there are many Anti-Virus websites that offer free online virus detection and removal services.

Removal tools - If you have an Anti-Virus software then you can go to the website of that software and download removal tools designed specifically for the virus. However, you must find out the name of the virus that infects your PC beforehand.

If you have a backup of all your important files, you can also consider formatting your hard disk.

How a computer virus works!

noreply@blogger.com (meor) — Tue, 13 Mar 2007 14:15:00 +0000

by: Silent One

Computer viruses are mysterious and grab our attention. On the one hand, viruses show us how vulnerable we are. A properly engineered virus can have an amazing effect on the worldwide Internet. On the other hand, they show how sophisticated and interconnected human beings have become.

For example, the thing making big news right now is the Mydoom worm, which experts estimate infected approximately a quarter-million computers in a single day (Times Online). Back in March 1999, the Melissa virus was so powerful that it forced Microsoft and a number of other very large companies to completely turn off their e-mail systems until the virus could be contained. The ILOVEYOU virus in 2000 had a similarly devastating effect. That's pretty impressive when you consider that the Melissa and ILOVEYOU viruses are incredibly simple.

In this article, we will discuss viruses -- both "traditional" viruses and the newer e-mail viruses -- so that you can learn how they work and also understand how to protect yourself. Viruses in general are on the wane, but occasionally a person finds a new way to create one, and that's when they make the news.

Top 10 Ways To Protect Yourself From Computer Viruses

noreply@blogger.com (meor) — Tue, 13 Mar 2007 14:03:00 +0000

by: Jim Faller

As more and more people are becoming comfortable using their computers at school, home or in the office it’s only a matter of time before they encounter a computer virus. Here are our top 10 steps to protect you from computer viruses.

Use a high quality anti-virus program. There are many different anti-virus computers programs on the market some of them are better than others. Look to reputable computer magazines or websites for ratings to help you find the one that matches your needs.

Always use your anti-virus software. Make sure your anti-virus software is always turned on and scanning, incoming and outgoing email messages, and any software programs you run.

Keep your antivirus programs up to date. Most programs come with a yearly subscription make sure you take advantage of the updates. More advanced programs allow you to schedule updates or full system scans for “off hours” like 2AM when you aren’t likely to be using your computer.

Keep your computer up to date. From time to time operating systems fall victim to security holes or issue updates. Make sure you check periodically to make sure you are running stable up to date versions of your software.

Backup your data regularly. Most windows computer users keep their documents in the “My documents” folder. This makes it easy to back up all of your important documents. Make weekly or monthly copies to CD or USB drives.

If you use floppy disks or USB drives on public computers like your school computer lab, Kinko’s, or even digital photo printing store make sure you scan them for viruses. Public computers are notorious for not being up to date and properly protected.

Be wary of email attachments. Treat any email attachment as potentially dangerous. Never open attachments from people you weren’t expecting. Also be careful of attachments from people you know but weren’t expecting. Many computer viruses replicate themselves by reading the contacts from an infected computer.

Use text email if possible. While HTML email is prettier and allows you more control over formatting it also can carry computer viruses. If you use text based email the only way to get a virus is by opening an attachment.

Use downloaded freeware and shareware files or software with caution. Try to download them from popular reputable sources that scan the programs before they are uploaded. To make sure you are safe scan the program before you install it on your computer.

Be wary of links in IM or instant messaging software. Don’t accept invitations from people you don’t know and never click a link from someone you don’t trust, they can easily redirect you to another website that will try to install a virus on your computer system.
