Invest in Antivirus Software for Safer Surfing

noreply@blogger.com (TOPGUN) — Wed, 29 Sep 2010 08:17:00 +0000

Advertising feature. The Internet is a tool that has changed our lives and, without doubt, the way that most of us communicate. Unfortunately, it has also greatly facilitated the spread of computer viruses. But is there any way to combat this threat? Investing in antivirus software may be the answer.

A virus is a malicious computer program which can cause absolute chaos to whole networks of computers at the same time. The effect of a virus differs depending on its intent: whether it was created to modify, delete or steal data or to cause real destruction to a hard drive.

Other more sophisticated viruses are designed to allow their creators control over your PC. This enables them to hack into your computer and access your information.

The term computer virus was coined because the viruses share some traits with biological viruses. A computer virus passes from one computer to another, for example, in much the same way as a biological virus passes from person to person.

A computer virus must ‘piggyback’ on top of another program or document in order to attach itself. Once it is running, it can then infect other programs or documents. Viruses can be opened in emails, attack through downloaded files or simply appear when you access a website.

Virus creators always have tricks up their sleeves so that users will open their files. With viruses like Trojan horses, for example, they hide them within a harmless-looking file such as a picture of a celebrity. This makes it easier for the malicious software to be installed onto a computer.

There are many different types of viruses being created all the time. The Worm is a particularly nasty type, because it can replicate and spread itself over an entire network. They can also sit on your machine for months or even years before being triggered at a certain date or time to wreak havoc. Worms are becoming increasingly common and are among the biggest troublemakers on the Internet.

After reading this, you will probably never want to turn on your computer again, let alone open any files or emails! As more and more of these viruses are changing and becoming more advanced, the need for protection has become that much greater.

But don’t despair, as there are many reliable versions of antivirus software out there which you can download to maximise the security of your PC. Even better, there are many different versions of free antivirus software that you can download to protect your computer against malicious threats without incurring any cost.

There is also good news for Apple Mac users, as they have slightly less to worry about; in terms of viruses, there aren’t so many floating around which target Macs. That isn’t to say that things won’t change, however. Recent reports have seen more and more cyber criminals turning to the Mac platform as more people begin using it than ever before.

As this trend is likely to continue, it is recommended that you invest in some Mac antivirus software to protect against the threat. Antivirus software for Mac is in limited supply, but there is still plenty to choose from.

Mobile phone-based viruses are also new. Many antivirus software developers are addressing this threat with new mobile antivirus products that can run on your mobile.

Depending on how much money you spend on PC antivirus software, you will get various extras that offer additional protection. Whichever method of antivirus software you choose to invest in, however, they will all still work on the same basic principles.

Antivirus software is designed to keep your PC free from the malicious computer viruses and worms mentioned already. This is done by scanning your PC’s files for known viruses; if one of these is detected, then the software will inform you of the situation before taking steps to remove the threat.

Good antivirus software will also automatically check any files being transferred to and from your computer, and at a minimum should scan all attachments on incoming emails (even if this option has been disabled).

There is one thing that you must remember about PC virus protection: hackers are developing new bugs all the time, so it is important to regularly update your antivirus software. If you don’t download the new versions, you won’t be protected against the latest dangers.

Most antivirus companies release weekly updates of their databases to help keep you safe. Your antivirus software uses these weekly updates, also known as virus signatures or definitions file, to identify newly discovered viruses.

If you scan your computer with a definitions file which is out of date, the software may not detect a problem lurking in the background. A good way of making sure nothing slips through the net is to set up an ‘on-demand’ scan. This will see your virus scanner checking through all your files on your hard drive once a week with all of the latest updates. You can’t be too careful with these crafty viruses!

It is also important to get your virus protection from a reputable company; where would get your updates from if the company went bankrupt in six months time?

Having antivirus software installed on your computer may not keep you 100 per cent protected against every virus attack, but it will certainly protect you a lot better than if you didn’t have it at all. You can enhance your protection even further by having multiple antivirus software products and by always remaining vigilant online.

As well as having antivirus software installed on your computer, you can also take steps to protect your PC against attack. This can be as simple as being on guard when opening unknown email attachments, only downloading software from known websites and keeping your logins different for lots of sites. Taking these precautions will help to keep your computer protected against malicious threats and viruses.

So long as computer viruses change and evolve as rapidly as they do, there will never be a program that will be able to cure everything, but you can certainly still go a long way to keeping yourself safe.

"If you change a filename extension,the file may become unusable"

noreply@blogger.com (TOPGUN) — Tue, 06 Jul 2010 04:28:00 +0000

Trouble:

“If you change a filename extension,the file may become unusable. Are you sure you want to change it?”

Warning can be seen in snapshot below.

The simplest way to fix such issue is to make the file extensions hidden. When you do that, windows will take care that the file extensions are not changed while renaming the file. To make the file extensions hidden, follow the below steps:

1. Open My Computer, go to Tools > Folder Options > View

2. Check the option “Hide extensions for know file types”.

3. Click Apply and OK.As seen in image below.

Method 2 :

Always provide the extension to the file explicitly as it was previously. For example if you want to rename a zip file from old name file1 to new name file2, make sure you rename the file from file1.zip to file2.zip. This means you have to type the extension manually.

We hope this helps to understand why the warning got flashed

Purchase of Antivirus Softwares

noreply@blogger.com (TOPGUN) — Sun, 16 May 2010 15:27:00 +0000

Why Buy Antivirus Software?

Today, an unprotected computer isn’t just vulnerable, it’s probably already infected. New viruses, spyware, trojans, worms, and other malware are created every day. New threats are disguised to bypass other security measures, and specifically designed to catch you and your PC off guard.

The virus landscape has also changed; viruses that used to be annoying pranks have evolved into pernicious threats capable of not only destroying your computer, but stealing your information and identity.

The benefits of installing a basic security solution on your PC are obvious, but the cost in system slowdown used to make it tough to bear. Luckily, modern antivirus software haven’t just improved their level of protection, they’ve significantly improved resource efficiency and overall speed. You can have ultimate protection without giving up your resources. With advanced technologies and straightforward usability, antivirus software is more effective than ever, and doesn’t require constant maintenance from you. Say goodbye to annoying security warnings and noticeable slowdown; current antivirus programs deliver constant protection and can actually speed up your computer.

The last generation of antivirus software brought advanced heuristic detection into the mix. Continuing to improve, the 2010 lineup of antivirus products often incorporate further developed proactive protection with better behavior checking and even file reputation analysis. Several of the software incorporate ‘in the cloud’ security and other advanced technologies to increase safety and convenience. From gamer modes, to battery saving settings, to integrated web link scanners; antivirus applications are more versatile and have upped the ante for features and functionality.

On this site you’ll find a side-by-side comparison of the best antivirus software, helpful articles, security tips and tricks, buying guides, videos, and comprehensive reviews to help you make an informed decision on which security software is right for you.

At TopTenREVIEWS We Do the Research So You Don’t Have To.™

What to Look For in Antivirus Software

All security software is not created equal. Like all consumer products, antivirus software has the good, the bad, and the mediocre. The choices for antivirus protection are many and varied. Although we haven’t reviewed each and every product available, we feature the absolute best antivirus software available today from a number of providers (including big-hitters, lesser-knowns, and new-comers), and compare them so you can match your needs with the right software.

Remember when it really comes down to it, effectiveness and usability can either make or break antivirus software. Security programs are only as good as their level of protection, and if you can’t figure out how to use it, you won’t. Our top-ranked antivirus software combine optimal security with user-friendly features and tools.

Below are the criteria TopTenREVIEWS uses to evaluate and compare antivirus software:

Scope of Protection
While most security solutions tout “multi-layered” protection, “360 degree” defense and/or even “100%” security, some are certainly more thorough than others. The best antivirus solutions will include traditional protection from viruses, worms, Trojans and spyware, but should also include defense from keyloggers, phishing scams, email-borne threats and rootkits. While antivirus programs are by no means full-blown internet security suites, they should protect from as many threats on as many fronts as they can.

Effectiveness
Antivirus is specifically designed to protect your computer, so if it doesn’t do that well, what good is it? All the features, bells and whistles, or sleek interface can’t make up for poor performance. We look at results from the industry-standard security software testers and professional security organizations to find the most effective software available and evaluate overall effectiveness. In general, our highest ranked programs are also the most effective.

Ease of Installation and Setup
Security software shouldn’t be a chore to install, and should have you protected as soon as possible. From download to install, to the first scan; implementing antivirus software should be quick and easy.

Ease of Use
Antivirus software is complex stuff, but shouldn’t require a degree in computer security. The best security programs have all the features security experts want, but are just as easily used by a beginner. Everyday computer users want a security solution that they can install and forget about; software that doesn’t require constant maintenance or have annoying interruptions. The best antivirus software is flexible enough to do exactly what you want to (even if that means running by itself).

Features
A well-rounded feature set takes a security solution from good to great. More than bells and whistles, added features provide security, usability and performance benefits.

Updates
Security software is only as good as its latest update. Viruses are being identified and added to signature databases all the time, so it’s important that your virus definition list updates accordingly. Modern antivirus software are equipped with automatic updates that perform regularly enough that you get faster updates that don’t slow down your system. The best security providers even “push” updates to you as soon as they’re available.

Help & Support
The best software doesn’t require reading an in-depth manual to use, but still has one available. For specific questions, troubleshooting, and additional help, the best antivirus manufacturers provide superior product support online and off. Additional support for software may come in the form of assistance over the phone, email, live chat, or through a number of additional resources (knowledgebase, FAQs, tutorials).

A well-balanced antivirus solution is effective, efficient, and easy to use. Combining all the right features with a usable interface; our top antivirus software choices deliver the best security and usability without a serious investment in time, money, or system resources.

New virus infects PCs, whacks SCO

noreply@blogger.com (TOPGUN) — Tue, 04 May 2010 09:55:00 +0000

A mass-mailing virus that quickly spread through the Internet on Monday planted a file that will instruct infected computers to attack the SCO Group's Web server with a flood of data on Feb. 1.

The virus--known as MyDoom, Novarg and as a variant of the Mimail virus by different antivirus companies--arrives in an in-box with one of several different random subject lines, such as "Mail Delivery System," "Test" or "Mail Transaction Failed." The body of the e-mail contains an executable file and a statement such as: "The message contains Unicode characters and has been sent as a binary attachment."

"It's huge," said Vincent Gullotto, vice president of security software maker Network Associates' antivirus emergency response team. "We have it as a high-risk outbreak."

In one hour, Network Associates itself received 19,500 e-mails bearing the virus from 3,400 unique Internet addresses, Gullotto said. One large telecommunications company has already shut down its e-mail gateway to stop the virus.

Once the virus infects a Windows-running PC, it installs a program that allows the computer to be controlled remotely. The program primes the PC to send data to the SCO Group's Web server, starting Feb. 1, a virus researcher said on the condition of anonymity.

The SCO Group has incurred the wrath of the Linux community for its claims that important pieces of the open-source operating system are covered by SCO's Unix copyrights. IBM, Novell and other Linux backers strongly dispute the claims.

Panda Security unveils 2010 line-up and 80% performance gains

noreply@blogger.com (TOPGUN) — Mon, 14 Sep 2009 16:35:00 +0000

Panda Security has this week launched its 2010 line-up of security products and the focus this year seems to be on performance.

There are four versions of the latestprotection including:

Panda Antivirus for Netbooks ($39.95)
Panda Antivirus Pro 2010 ($39.95 one PC, $49.95 three PCs)
Panda Internet Security 2010 ($59.95 one PC, $79.95 three PCs)
Panda Global Protection 2010 ($69.95 on PC, $89.95 three PCs)

Each version takes advantage of a cloud computing solution Panda call Collective Intelligence. Using that has helped the company minimise the resources required to protect your machine and boast just an 8MB memory footprint while running. Panda are also claiming an 80% performance improvement over previous editions, 60% improved browsing speed, and 40% improved downloading speed.

In the same way Kaspersky introduced its Ultra Portables solution earlier this month; Panda has decided to target netbooks with one of its Antivirus SKUs giving antivirus, anti-spyware, firewall, ID protection, anti-phishing, and anti-rootkit protection for mobile users.

For those not using a netbook there are three options. The Pro suite gives you a basic range of protection, Internet Security adds 2GB of online backup and recovery tools, anti-spam, parental controls, Web Filter, and Information Filter technology. Global Protection takes the online backup storage to 5GB, adds CD/DVD backups, and introduces PC tune-up.

All Panda Security 2010 products are now available to buy via the Panda Security website.

Read more at the Panda Security press release

Matthew’s Opinion

There seem to be three trends appearing with security vendors at the moment: performance, cloud computing, and netbook support. All three of those are very welcome focus points in my opinion.

Netbooks are a growing market, but have limited performance so a lightweight security solution is going to help keep them performing well while remaining protected. Performance of any security solution is always key and most vendors have come a long way with their latest solutions, for example, Norton 2009 was a vast improvement over earlier editions.

Cloud computing is still relatively new in terms of providing protection, but it is clearly a growing trend. Signature-based solutions alone are just not going to be good enough in the future and an online database and constant update/checking system is going to be key over the next few years.

Panda’s latest products seem to offer everything you need, but it looks like you need to buy at least Internet Security 2010 if you don’t want to rely on other security software as well. I don’t appreciate them charging extra for a three PC license though and I hope they revise that so the one PC license price becomes the three PC license price.

AVG decides iTunes is a virus

noreply@blogger.com (TOPGUN) — Mon, 14 Sep 2009 16:29:00 +0000

If you are a user of AVG and iTunes then you might have had an issue over the weekend. An update to the AVG antivirus database was released on Friday, but for some reason it made AVG view some of the files used by iTunes as malicious

I just woke my computer (Windows Vista, AVG 8.5) from standby, plugged in my iPod Touch, and it complains that one of the iTunes DLLs is infected with the “Small.BOG” Trojan.
I hit “Heal” and all was well. iTunes wouldn’t run, obviously. So I downloaded and ran up the latest iTunes installer to repair the installation, and got “Multiple threat detection” and a list of all of the iTunes Localisation dlls.

A similar thread also appeared on the Apple forums as the number of users experiencing the problem started to grow. AVG reacted quickly though, admitted it was a false alarm, and issued a “How to fix” bulletin on Saturday. Anyone suffering with this problem can take the following steps to solve the issue:

Update AVG
If iTunes does not work after that open the AVG user interface.
Choose “Virus Vault” option from the “History” menu.
Locate the iTunes file that was incorrectly removed and select it (one click).
Click on the “Restore” button.

What is spoofing?

noreply@blogger.com (TOPGUN) — Sun, 23 Aug 2009 10:47:00 +0000

If you are receiving bounce back messages from emails that you HAVEN'T sent you have probably been 'spoofed'

Email spoofing is when the sender changes the name in an outgoing email so that it looks like the email came from somewhere or someone else. This practice is often used by spammers to stop people finding out who they are. It also means that when the spam mail is rejected by the addressee's mail server, the bounce back message goes to whoever was specified in the outgoing mail rather than to the spammer themselves.

At present there is nothing we can do to avoid this nuisance. If you have been spoofed, please simply delete the bounce back messages. It doesn't mean that anyone has accessed your email account. You will probably find you receive a few for a short while and then they will stop.

Virus-writing hackers are biggest threat

noreply@blogger.com (TOPGUN) — Sun, 23 Aug 2009 10:43:00 +0000

We're in trouble when the two meet - "It isn't rocket science," says expert

Hackers who crossover into virus writing territory present the biggest danger to corporate computer systems as they perfect the 'blended threat' seen in recent virus outbreaks such as Sobig.

That's the assertion of Sarah Gordon, senior research fellow at Symantec Security Response, who has worked with the White House and the FBI to research the psychological profile of hackers and virus writers.

Gordon told silicon.com that hackers are driven by the motivation to complete a technology challenge and are usually not interested in the basic task of writing viruses and worms.

"There are people in the virus writing community who hack and people in the hacking community who write viruses but for the most part they are very separate communities. The virus writers are seen at the lower end of the food chain," she said.

But Gordon warned that creating a virus such as Sobig or Bugbear, only with much more damaging payloads, is well within the capabilities of even the most inexperienced hacker.

"Many of the threats are the result of the crossover between hackers and virus writers. Erasing a hard drive is a couple of key strokes. It isn't rocket science. A hacker of any skill level could write a self-replicating program but most find it too boring," she said.

And it seems the traditional stereotype of a spotty teenager hacking away in a dark bedroom is nothing more than a myth from the movies.

"The population is diverse. It just takes the ability to manipulate a computer system. It is not guys sat in a basement with piercings everywhere. It could be the 50-year-old accountant because she is bored, or the boss' 15-year-old daughter, or your 9-year-old nephew," she said.

There is also a distinct difference between hackers and virus writers, according to Gordon's research.

"Virus writers have normal relationships with peers and families. Hackers tend to be more introverted. Hacking is a very personal thing. One is power and control and the other is letting go."

Although Gordon works for a security software company, she says 'ethics' education at an early age would help prevent children and teenagers using their computer knowledge to cause damage.

"One thing that is important is introducing ethics in technology at an early age. On the computer there is less context and security. Teaching them that there's a person on the end of that modem is important," she said

The World's Most Dangerous Virus

noreply@blogger.com (TOPGUN) — Sat, 22 Aug 2009 10:13:00 +0000

The World's Most Dangerous Virus: by Michael Robertson

Imagine if a computer virus emerged that secretly attached itself to one of the most popular software programs ever. Imagine if the largest media outlets unwittingly praised this secret pairing, encouraging millions of people to install it. Imagine if none of the major antivirus programs would detect it. Imagine if once installed, it could alter anything on your computer without your consent or knowledge. Imagine if the virus was at the control of a greedy entity that has repeatedly trampled on consumers and smaller companies to advance its corporate agenda. Imagine if it could force everyone who wanted to communicate with you to also carry the virus so it would insidiously spread person to person. Sound like a scary sci-fi plot? It's not science fiction. This week MO3 will be released on the world. Here's how to detect it in your neighborhood and what you can do to protect yourself

The Trojan Horse

Press outlets will blanket the world with stories about Microsoft Office 2003. Most articles will tout seemingly innocuous features and feel good quotes from Microsoft like "this is our most important product release ever." Unfortunately the press won't talk about the dangerous software buried inside this release - MO3. This code will give Microsoft the ability to change anything on your computer at anytime they wish with no notification to you.

The Security Ploy

Post 9/11, few people question actions taken under the guise of "improved security" and this is how MO3 will be foisted onto computer users - as a feature to 'make you safer.' Computer users have understandably tired of the near daily worm and virus warnings, as well as the time-consuming patch process due to Microsoft's lax software standards and its focusing not on building secure products, but products that secure its monopoly market positions. To improve the predicament which they've created, Microsoft is forcing consumers to accept MO3 embedded into every computer. Listen closely and you'll hear Microsoft mouth pieces speak of "turning software into a service" which really means they will be changing the software on your computer whenever they feel like it. They will slowly limit your ability to run non-Microsoft software. They will restrict choices on your computer to only those products they approve. They will make changes which cripple other software programs or reduce their ability to interoperate with your computer so you will be forced to use exclusively Microsoft approved products.

History Repeats Itself

Microsoft may use this newfound power to fix some holes in their software, but they will also abuse this power to further their corporate monopoly and increase their control and profits. Microsoft has already embedded the MO3 virus into another operating system they have deployed, called Xbox. They now have the power at anytime to change all existing Xboxes which connect to the Internet, and they are already misusing it. They have deleted files from users' computers without their knowledge or permission. They have added software which has removed the ability to run competitor's software. They have been changing users' systems without their consent and notification. They will do the same on Microsoft Windows based computers once MO3 is installed.

Microsoft management has shown to be deceitful and dishonest and will continue this behavior. Twice Microsoft has been found guilty by the Federal government of using illegal tactics to drive competitors out of business and extend their monopoly. December 1st, 2003 a trial will take place in Seattle Washington where more of Microsoft's past behaviors will come to light.

Infecting Friends

Microsoft Word (.doc) file open in StarOffice 7

To stop the advance of competing products and to force users into purchasing new software with the MO3 virus, Microsoft is making certain Microsoft Office 2003 files unreadable by all older versions of Microsoft Office and all competing office suites. Products like Sun's StarOffice are getting extremely good at interoperating with Microsoft word processing, presentation and spreadsheet files making it possible for people to spend close to $50 for an office suite instead of giving $400 or more to Microsoft. To blunt this and force users of older versions of Microsoft Office to buy new software, Microsoft has changed the specifications for some files.

Again under the umbrella of "security," Microsoft is implementing features which limit who can open and edit documents to further thwart competition. Microsoft Office 2003 gives its users the ability to control who can read and edit certain documents, but only if they use the latest Microsoft software. If one user within an office uses this feature, all others will be unable to use any other office suite to access that document. They will not be permitted to run Linux software, they will be required to purchase and run additional copies of Microsoft Office 2003. Since documents are frequently emailed around via the Internet, this will force others to accept Microsoft's software or be unable to communicate. Microsoft refers to this as IRM for "information rights management," but it's really an "infection relay method" designed to force everyone to adopt MO3. They will be using scare tactics about leaked memos or misdirected emails to persuade unwitting computer users to deploy this technology. Doing so will create a viral growth of MO3 which will give MS unlimited power over every computer.

Universal MO3

MO3 will not only come with Microsoft Office 2003, but with future Microsoft products as well. The same technology will be embedded into the next version of Microsoft's operating system software so all users will have to accept it with their new computer. Latest estimates indicate this new software will not ship until 2006, so between now and then, watch for Microsoft to secretly embed MO3 into updates or security patches that they promote for their existing product line.

Protect Yourself

Microsoft Excel (.xls) file open in StarOffice 7

There are precautionary measures you can take to fend off MO3. First off, do not purchase and install Microsoft Office 2003. Also, discourage those around you from purchasing Microsoft Office as well, since one infection will quickly grow. If you need a new office suite, check out the solid and affordable StarOffice 7.0 which runs equally well on Microsoft Windows or Linux computers, and can be purchased online and immediately downloaded and installed. Encourage those penning articles and reviews to fully inform their readers of the dangers of Microsoft Office 2003. Finally, encourage them to do in-depth reviews of Microsoft Office 2003 vs. Sun's StarOffice 7.0 so people can make informed decisions about the benefits and risks of either product.

The Most Dangerous Computer Viruses in History

noreply@blogger.com (TOPGUN) — Sat, 22 Aug 2009 10:05:00 +0000

Computer viruses have a relatively short history by the damages caused by some of the most dangerous viruses pushed cyber-experts to open a chapter that includes a huge database on computer viruses and the cost of damages caused along with companies, government and universities highly affected by malware.

Here are some of the most dangerous computer viruses in history:

Jerusalem - 1988

This is one of the first MS-DOS viruses in history that caused enormous destructions, affecting many countries, universities and company worldwide. On Friday 13, 1988 the computer virus managed to infect a number of institutions in Europe, America and the Middle East. The name was given to the virus after one of the first places that got "acquainted" with it - the Jerusalem University.

Along with a number of other computer viruses, including "Cascade", "Stoned", "Vienna" the Jerusalem virus managed to infect thousands of computers while still remaining unnoticed. Back then the anti-virus programs were not as advanced as they are today and a lot of users had little belief of the existence of computer viruses.

Morris (a.k.a. Internet Worm) - November 1988

This computer virus infected over 6,000 computer systems in the United States, including the famousNASA research Institute, which for some time remained completely paralyzed. Due to erratic code, the worm managed to send millions of copies of itself to different network computers, being able to entirely paralyze all network resources. The damages caused by the Morris computer virus were estimated at $96 millions.

To be able to spread the computer virus used errors in such operating systems as Unix for VAX and Sun Microsystems. There were a number of other interesting ideas used by the virus - for example it could pick user passwords.

Solar Sunrise - 1998

A decade later the situation didn't change, it might have gotten even got worse. Using a computer virus, hackers, in 1998, penetrated and took control of over 500 computers systems that belonged to the army, government and private sector of the United States. The whole situation was dubbed Solar Sunrise after the popular vulnerabilities in computers that run on the operating system called Sun Solaris. Initially it was believed that the attacks were planed by the operatives in Iraq. It was later revealed that the incidents represented the work of two American teenagers from California. After the attacks, the Defense Department took drastic actions to prevent future incidents of this kind.

Melissa - 1999

For the first time computers got acknowledged with Melissa computer virus on March 26, 1999, when the virus shut down Internet mail system, which got blocked with e-mails infected by the worm. It is worth mentioning that at first Melissa was not meant to cause any harm, but after it overloaded servers the virus led to unpredictable problems. For the first time it spread in the Usenet discussion group alt.sex. Melissa was hidden within a file called "List.DiC", which featured passwords that served as keys to unlocking 80 pornographic websites. The original form of the virus was sent through e-mail to different users.

Melissa computer virus was developed by David L. Smith in Aberdeen Township, New Jersey. Its name comes from a lap dancer that the programmer got acknowledged with while in Florida. After being caught, the creator of the virus was sentenced to 20 months in federal prison and ordered to pay a fine of $5,000. The arrest represented a collaboration of FBI, New Jersey State Police and Monmouth Internet.

Melissa had the ability to multiply on Microsoft Word 97 and Word 2000, as well as Microsoft Excel 97, 2000 and 2003. In addition, the virus had the ability to mass-mail itself from Microsoft Outlook 97 or Outlook 98.

I Love You - May 2000

Using a similar method as the Melissa, the computer virus dubbed "I Love You" managed to infect millions of computers around the world in just one night. Just like Melissa this computer virus sent passwords and usernames, which were stored on the attacked computers, back to the developer of the virus. After authorities traced the virus they found that a young Filipino student was behind the attack. The young man was released due to the fact that the Philippines did not have any law that would prevent hacking and spreading malware. This situation served as one of the premises for creating theEuropean Union's global Cybercrime Treaty.

The Code Red worm - July 2001

This 21st century computer virus managed to penetrate tens of thousands of systems that ran Microsoft Windows NT as well as Windows 2000 server software. The damages caused by the Code Red computer virus were estimated at a total of $2 billion. Core Red was developed to use the power of all computers it infected against the official website of the White House at a predetermined date. In collaboration with different virus hunters and tech firms, the White House managed to decipher the code of the Code Red virus and stop traffic as the malware started its attacks.

Nimda - 2001

Shortly after the September 11 tragedy this computer virus infected hundreds of thousands of computers worldwide. Nimda was considered to be one of the most complicated viruses, having up to 5 different methods of infecting computers systems and duplicating itself.

Downadup - 2009

The latest and most dangerous virus is the "downadup" worm, which was also called "Conficker". The computer security company F-Secure stated that the computer virus has infected 3.5 million computers worldwide. This malicious program was able to spread using a patched Windows flaw. Downadup was successful in spreading across the Web due to the fact that it used a flaw that Microsoft patched in October in order to distantly compromise computers that ran unpatched versions of Microsoft's operating system. But the greatest power of the worm is believed to be the ability of computers, infected with the worm, to download destructive code from a random drop point. F-Secure stated that three of the most affected countries were China, Brazil and Russia.

6 ever Most Dangerous Computer pc viruses and worms

noreply@blogger.com (TOPGUN) — Thu, 20 Aug 2009 11:12:00 +0000

Viruses and worms are a cause for thousands of losses all over the world. There are number of viruses and worms created. Below i have listed 6 most dangerous and havoc creating viruses that affected millions of computer users over the world. The order of viruses is not important.

Most dangerous computer viruses :

1. ILOVEYOU :

This ILOVEYOU worm is considered to be most dangerous worm ever created. It was written in VBScript. It was first noticed in Philippines on May 4 2000 and then spread all over world in just one day, affecting 10% internet users and causing loss of about $5.5 billion. The worm arrived in email inbox with subject “ILOVEYOU”. Hence, called ILOVEYOU worm. It had an attachment “LOVE-LETTER-FOR-YOU.TXT.vbs” . The worm overwrote many important files, with music, multimedia files with a copy of itself attached to each file. Also, it sent the worm to everyone on victim contact list. Thus, worm spread very fast. Only windows users were affected.

2. Mydoom :

Mydoom , a computer virus affected Microsoft Windows. After it was first noticed on January 26, 2004, it became fastest spreading computer virus ever, breaking record of Sobig worm. Mydoom was designed to send junk emails from infected computers. The actual worm programmer is still unknown.

3. Virut virus :

This Virut virus infects executable portable files such as .exe and .scr andeach time it propagates it uses Polymorphism - to evade detection. On infected machine, virus opens a backdoor connecting with an IRC server which is prespecified by virus programmer. This backdoor allow attacker to download additional malware to victim computer. This virus affected and shut down court system computers of Texas this February.

4. Blaster worm :

This Blaster worm - a computer worm that affected computers running Microsoft operating systems. But, the spread of this worm was limited by filtering of ISP and its publicity. The worm was designed to start a SYN Flood on Aug 15, 2003 against port 80 of windowsupdate.com, intended to create a distributed DDoS attack against this site.

If the worm detects an internet connection, the system would become unstable and after displaying a message for 60 seconds, the system used to restart. The message displayed looked like:

“I just want to say LOVE YOU SAN!!”

“billy gates why do you make this possible? Stop making money

and fix your software!!”

5. Sobig worm :

This worm ws detected in Aug 2003 which affected millions of internet connected windows operating systems. The worm was written using Microsoft Visual C++ compiler and compressed using tElock. The most destructive version was Sobig.F .

This worm was worm as it replicated itself and also a Trojan Horse as it appeared other than malware. The programmer of this worm is still not known.

6. Conficker virus :

This virus came into role in November 2008 and affected millions of computer. Basically, its a worm capable of replicating itself and thus can spread fast. The worm spreads itself primarily through a buffer overflow vulnerability in the Server Service on Windows based computers.

When this worm is executed on a computer, it is capable of disabling Windows services such as Windows Update, Windows Defender, Windows Security Center and even Windows Error reporting.

But, the threat due to this worm is reduced as most antiviruses are now detecting this worm and its further spread is thus prevented. This worm is mainly spreading in China, followed by Argentina, Brazil, Russia, and India - where software update is done to less extent.

So friends, this is all about viruses. These are most dangerous viruses or worms that affected millions of worldwide computers. I just wanted to say that keep your antiviruses updated to prevent yourself from being affected by such viruses and worms. If you think any other virus or worm needs mention over here, please mention it in comments section. I will update the article.

Enjoy…..

Top Ten Most Dangerous Viruses

noreply@blogger.com (TOPGUN) — Thu, 20 Aug 2009 09:27:00 +0000

Sophos recently published the top ten most dangerous and most active viruses that were spotted online in November. Sadly, the results of this chart aren't very flattering for security experts worldwide as this particular month has seen a record number of malware riding the online waves. This was also a prolific time for one of the Sober variants, Sober-Z having

real chances of becoming the number one virus this year.

The report has been put together thanks to the Sophos global network of monitoring stations and it proves that even if Sober-Z was spotted near the end of the month it managed to spread so fast and on a wide scale that it made up for its late entry and in the end accounted for one in every 13 emails sent.

Sober took the Internet by storm and also managed to take the lead of the Sophos virus chart, while Netsky-P, the worm written by convicted German teenager Sven Jaschan, fell to second position after dominating the number one spot for the past four months. The new variant of Sober has been "awarded" with a 42.9% share of all spotted viruses and it spreads as an email attachment. Once installed it attempts to block antivirus software and it scans the computer for email addresses in order to automatically forward itself to the new destination.

The November top virus chart includes three different families, Netsky, Mytob and Zafi, which proves virus authors are still inclined to make new variants of malware that has been around for some time.

The complete top 10 most dangerous viruses in November is the following:

1. Sober-Z

2. NetSky-P

3. Mytob-GH

4. Mytob-EX

5. Zafi-D

6. Mytob-BE

7. Zafi-B

8. Mytob-AS

9. NetSky-D

10. Mytob-C
