Secrets of Data Recovery

noreply@blogger.com (Unknown) — Sun, 18 Jan 2009 01:45:00 +0000

Data recovery is something we hope that we will never need. Whether you simply make the mistake of deleting important software or you lose it all in a computer crash, that valuable asset of information may seem like it is lost forever. But, if you have complete and quality data-recovery software on your computer or through your system, you can be confident that it has a backup and it is there even though these things will happen to you. This can be so important when it comes to safeguarding your business or your personal information.

What people do not realize is that there are a number of ways that things can go wrong on their computers. Whether you are responsible for the computers of a large corporation, a small business or even just your own personal computer, having a way to restore information when things go wrong is quite important. Here are some things that could happen to you, well, anytime, even right now. Your computer could be running slowly or be loaded with powerful spyware that can destroy files, transmit personal data or, even worse, cause the computer to crash. All of a sudden, it’s gone. Or, you could be working along nicely without a care in the world and bam! A power surge, an electric storm or something else electrical happens and it’s all gone.

There are many more ways in which you can lose all of the personal data that is stored on your computer. You don’t even have to have the programs running to lose it. Nevertheless, many people mistakenly believe this will not happen to them and therefore do not do anything to prevent this total loss. Data recovery is necessary for this not to happen. The strange thing is, it takes only minutes to install and use and it virtually and it takes care of itself. It is not overly costly either. So, why don’t more people use data recovery? They just don’t realize its importance. And that is one mistake we don’t want to make. Data recovery is a need all computer users have.

Can Spyware Blaster Protect Your P.C. ?

noreply@blogger.com (Unknown) — Wed, 14 Jan 2009 19:40:00 +0000

By browsing a web page, you could infect your computer with
spy ware, ad ware, dialers and hijackers. These, unwelcome
guests, are some of the fastest growing threats on the
Internet today. It is important to protect your computer
and one of the most powerful software products, available
for this, is Spy ware Blaster, a program created by Java
cool.

How are you affected?

A spyware program will record every keystroke and e-mail as
well as every web page you visit and every chat session.
Some spyware programs will try to take control of your
homepage, search page and other browser settings. Some may
silently download themselves onto your computer. Others may
pose as legitimate programs and persuade you to download
them.

Private and confidential information extracted from a
user's computer may be put on the Internet before he can
realize that he is a victim of these malicious programs.

A Microsoft program called ActiveX is used to download
software from websites for supporting legitimate services
like file viewers or games. ActiveX can also be used to
download spyware, hijackers, dialers and ad ware. Spyware
Blaster can make it difficult for these ActiveX programs to
run on your computer. It can also protect your computer
from certain cookies while running Mozilla based browsers
like Fire fox.

The major anti-virus software product manufacturers have
ignored the risks of spyware, hijackers, dialers and ad
ware till now. Due to this, users have little knowledge of
the software products that can be effective in detecting
and eliminating them. One of the most powerful products
available to provide security from spy ware is Spyware
Blaster.

Spyware Blaster

Spyware Blaster is a freeware that offers effective
protection from malicious Internet downloads. It disables
malicious ActiveX controls that are already present and
prevents downloads of malicious ActiveX controls from a web
page. Its current database contains 822 items against which
it provides protection. About 100 of these are tracking
cookies, used by advertisers.

Spy ware Blaster's Flash Killer capability enables it to
block the installation of distracting macromedia flash
content. It gives the user the option to block specific
search engine toolbars and browser plug-ins.

Basic Internet Security

noreply@blogger.com (Unknown) — Tue, 13 Jan 2009 08:22:00 +0000

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.

How to Increase Your Computers Speed

noreply@blogger.com (Unknown) — Tue, 13 Jan 2009 08:21:00 +0000

I'm sure you've come across tons of articles and even suggestions from some of your friends on how to get your computer to work faster. Its really not that hard to increase your internet speed. I'm going to make it real simple for you and you don't need to be a computer geek to make this work. The first thing you need to remember is to never, and I mean absolutely never download programs especially free software without reading the fine print. Most free computer software will bombard your computer with spyware which will eventually bring your internet speed to a screeching halt! If your computer is already infected with spyware you can download the leading spyware remover called ad-aware which will scan your computer and remove spyware and tracking cookies from your computer.

Another way of making your computer and internet connection faster is by clicking on start, then run and typing in msconfig. Go to start tab and remove any program except your antivirus software and any other program which you must have start when windows starts. This tip will increase your computer start up time dramatically!

Step number 3, and I do this almost on a daily basis is to clean up your internet cache. Go to your control panel which you can access from your start button and click on internet options. Go to temporary internet files and clear your history. I would recommend that you also set internet history to a maximum of 2 days. Next step is to delete your temporary internet files including offline content. Last step is to delete cookies. Be careful though because deleting your cookies will also delete useful information from your computer. You can read a how to on cookies here www.howstuffworks.com/cookie.htm.

These steps are the basics you can take which will speed up your internet connection immediately. I would also recommend doing a virus check on your computer on a weekly basis. If you don't have antivirus software, get it! You'll be happy you did. Just one virus can wreak havoc on your computer! Make sure you test your internet speed whether its broadband or dial-up, before and after you take these simple steps so you can compare if these steps you've taken have worked. Taking these basic steps will make you a happy surfer and will restore your faith in the World wide web!

A Brief Explanation of Computer Components

noreply@blogger.com (Unknown) — Tue, 13 Jan 2009 08:19:00 +0000

There are many fancy add-ons for computers, but the basic components of the computer are simple and universal. If 1 of these main components is missing, it’s not a computer.

The 4 essentials of every computer system are: a motherboard, a Central Processing Unit (CPU), memory, and a hard drive. These components are installed in a case to which are attached a monitor, a keyboard and a mouse. That’s your basic computer.

Mother WHAT?

The motherboard ("mobo" for short) is the foundation. Everything attaches to the mobo -- the CPU, memory, hard drive, monitor, mouse, keyboard, add-on cards, even additional peripherals like printers, scanners, and speakers. The motherboard is like the nervous system and skeleton of the human body -- it provides support for the internal components and also passes information between the computer parts.

CPU

If the motherboard is the nervous system, then the CPU is the brain. Most of the mathematical manipulations that make computers operate are done by the CPU. Other components may also have their own processors, but their results still have to be passed through the CPU.

The speed of the computer is usually measured by the speed of the CPU. Even though other factors also affect overall speed, the CPU rating is generally seen as the single most important measure of performance.

Modern CPUs are usually rated between 2.0 GHz and 3.0 GHz, although each passing month will see increasing performance. This measurement refer to the number of calculations the processor can make in 1 second. The higher the number, the faster (better) the computer.

CPUs generate a lot of heat doing this work, so they need a heat sink and fan to keep them from overheating. Heat is a major enemy of the computer and directly affects its life span.

Computer Memory

RAM (Random Access Memory) is the part of the computer that stores information the computer needs while it is operating. It is Random Access because the computer can get the data in any order, not necessarily the order in which it is stored. Generally speaking, the more RAM the better. 512 to 1024 megabytes is common for memory.

The most common type of RAM these days is DDR-SDRAM, which stands for double-data-rate synchronous dynamic random access memory. We already know what the RAM part means. DDR means that the data is accessed twice as fast as ordinary RAM.

The latest type of RAM is DDR2. It offers even faster access rates and is quickly becoming the standard for computer memory.

Hard Drive

All the data contained in RAM is lost when the computer is turned off, so there has to be a place to store it permanently. This is what the hard disk is for.

It holds the computer’s operating system. An operating system like Windows uses around 4 gigabytes of hard drive space. The extra space is used to install computer programs and to store your personal data.

80 gigabyte hard drives are common, but 400 GB units are available. Furthermore, you can install more than 1 in a computer case for added security and convenience.

Peripherals

All you need to complete the basic computer system is a monitor, keyboard and mouse.

Accessories like a printer or scanner are useful for office work, and gamers will probably want to add speakers and joystick controls.

So there you have it. The basic computer needs just 7 major components. For the best performance, these components must integrate well. The motherboard is the most important component for determining the type and specification of the other parts. Choosing an appropriate mobo for your computer needs is the first step and may require a quick call to your local geek.

Soon YOU will be considered the local geek!

Barebones Computers - Cheaper Than Discount PC's

noreply@blogger.com (Unknown) — Tue, 13 Jan 2009 08:16:00 +0000

Buying discount computers is something easy to do nowadays that computer prices have dropped. Despite the low prices, you may still find it difficult to settle on a single computer. Computers are built with so many varying features that finding exactly the right one for you may be difficult. Building your own system from a barebones system is an option to buying discount computers that will enable you to get what you want exactly and still enables you to save money.

Don’t think you can build a computer system? It’s true that building a computer system takes some time and a bit of knowledge about how computers work. When you start the building process with barebones systems you deduct some of the complication associated with building a computer system. Barebones systems have the basic components that you need to get started with building a computer system. Most of these systems include a motherboard, CPU (computer processing unit), and power supply encased in a computer case. Choosing a barebones systems is similar to buying discount computers. You will need to determine your needs to find just the right system for you.

Barebones systems are typically classified according to what they offer. While they contain the same basic components, the components enable you to perform different levels of tasks. Low-level barebones systems, which range in price from $100 to $200, will have components that are not as advanced as those in high-end barebones systems. Of the components in a barebones system, the processor is your main concern. There are basically two types of processors: Pentium and Athlon.

There is much debate about which processor is the best. Pentium is probably the most popular name in processors. Its name is synonymous with speed and power. With the introduction of the Pentium 4 processor, Intel suggests that pure multi-tasking is possible. Athlon may not be as popular with general consumers, but those individuals who understand the components of processors, such as clock speed, know that Athlon is at the very least in step with what the Pentium processor offers. Athlon 64, the most current processor that AMD offers

Once you select the barebones system with the essentials you need, you basically upgrade the barebones system to include the additional parts you need to create your ideal computer. After the processor, you want to consider memory, a hard-drive, and CD/DVD writer. Essentially, just as with the processor, you will need to determine what tasks you intend to perform with the computer. As a rule of thumb when buying discount components, you don’t want to build a system with the most high-end components. For starters, you will end up spending a significant amount of money (negates the purpose of choosing an alternative to buying discount computers) and the components will more than likely soon be replaced with a more high-end component.

Use a Spyware Remover Now

noreply@blogger.com (Unknown) — Tue, 13 Jan 2009 03:50:00 +0000

If you use the internet, “There is over 90% chance your computer is infected with spyware” - Source CNN.

Just think about it. You probably have at least one, if not more computers in your home. Most computers today have internet access. And if you receive email from others and surf to a couple of sites can you be almost completely sure you have some kind of spyware installed in your computer.

How dangerous are spyware?

Let me give you a short list of things spyware can do,

• Spyware can run completely hidden on your computer
• It can slow down your computer a lot
• It can spy on you and send everything you type to someone else
• It can record everything you do, allowing someone to see it later
• It can spy on you and send account information, passwords, credit card numbers and similar to a third party
• It can “steal” files, pictures, videos and more from your computer

Some spyware will do just a few things and others everything from the list above, and more.

You must keep your computer clean from spyware or risk loosing personal information, financial information and even your private photos or family videos.

Run a spyware scanner regularly to clean out any spyware that may have sneaked their way into your computer. Do note that antivirus software (even the most expensive ones) have problems to keep spyware out. So get a good anti spyware software and use it!

No matter what the spyware's purpose really is, the bottom line is that at the very least it will cause you countless hours of problem solving and slow downs on your computer.

Scan your PC now to make sure it is clean. If you find anything, avoid using any credit cards or visit your online bank until the PC is cleaned with a top anti spyware software.

There are many different types of software that can harm, cripple or just reside quietly inside your computer. Beside virus, the most common types are Spyware, Adware, Malware, Trojans, Backdoors, Bots and Dialers. They all have different agendas but will to a degree change the way your computer function and how well it works. This beside the obvious threath the program itself impose.

The Difference Between Spyware and Viruses
by Kara Glover
kara3334@yahoo.com

Shin, a fictional character whose name means "faith" or "trust," sits by his laptop in the living room of his home in Pyongyang, the capital of North Korea. He is busy at work for his boss, dictator Kim Jong-il. His job, to make sure some spyware gets into specific computers at the Pentagon so he can gain vital top secret information. He's particularly interested now that the United States government suspects his country might soon conduct its first nuclear test.

With spyware surreptitiously installed on the computers, he could, for instance, engage in the practice of keylogging. In other words, our "trustworthy" Shin could tract the actual keys on the computer hit by the Pentagon officials. This would help him learn their passwords, the content of email messages, encryption keys, or other means to bypass security measures at our nation's defense fortress. Shin's not interested in crashing computers at the Pentagon or making them otherwise operable. That would be too overt and might reveal him. He's simply after information.

There are other types of spyware, sometimes called "malware" because they don't actually spy on your computer habits. They might instead just barrage you with annoying popups, for instance. Or they might give you a different home page that isn't of your choosing, like one of an advertiser's. But for the moment those types of malware, or adware as it's sometimes called, aren't very useful for Shin. He wants to use spyware that actually spies.

Over on another part of the globe in Turkey, a fictional terrorist sits with his own laptop in a suspected al Qaeda terrist cell. But he's not out to infect computers with spyware. That's child's play. He's out to bring the house down. This story is strictly hypothetical. But let's say the terrorist wanted to disrupt the daily hubub at a major American corporation. He'd infect the computers with a virus!

The terrorist might try to attack the company's vast network by inserting a worm into it. Worms reside in RAM, and travel from machine to machine and, unlike the classic viruses, they attack the computers themselves rather than individual files. Very disruptive. This type of virus could potentially make the computers inoperable.

Bring down the goings-on at a major corporation by spreading a worm through the computer network, and the terrorist could have a field day. But let's hope not.

So to summarize, spyware often keeps track of your computer habits, and viruses are often out to disable computers in some way. Hence the difference.

Spyware and Adware - Are You Protected?

noreply@blogger.com (Unknown) — Tue, 13 Jan 2009 03:45:00 +0000

Spyware is without doubt the most prevalent threat to online computer privacy and security.

Exactly what is Spyware?

Spyware applications are programs and files that hide on your PC's hard drive without your direct knowledge. They allow hackers and advertising companies to track your every move, both online and even when you work offline.

Tracking the websites you visit, the items that you buy online, the emails you send and receive, your Instant Message dialog, and worst of all they can even record your credit card number, personal identification numbers, and all of your passwords.

If you use dial-up to connect to the Internet then spyware can be used to bill 900 numbers to your telephone bill.

Spyware allows hackers to take control of your browser and alter your computer system files.

These computer parasites slow down your Internet connection by inundating you with unwanted Spyware pop-up ads.

This is just a short list of the harm that Spyware can cause.

Note: Spyware and Adware cannot be detected by anti-virus and firewall software.

Some Disturbing Facts About Spyware:

· Spyware infects 91% of all computers. That equates to an alarming 9 out of 10 computers!

· 27.3 million Americans have been victims of identity theft in the last five years, including 9.91 million people or 4.6% of the population in the last year alone.

Keep reading to learn how to keep from becoming a victim of Identity Theft.

Have you noticed your computer running slower than ever?

The reason for that may have to do with online advertisers adding Spyware, or Adware to your computer without your knowledge.

Exactly what is Adware?

Adware works very much like Spyware.

Adware is software that will show you popup ads over and over. These files can also be extremely dangerous to your PC and could cause major problems with your Computer.

Note: This article is an excerpt from a SPECIAL REPORT entitled "Spyware! – How To Get And Stay Safe". In the full report you'll find the information you need to effectively protect your computer and personal information. Avoiding the grief of dealing with problems like Identity Theft among others.

10 Ways to Protect Yourself From Computer Viruses

noreply@blogger.com (Unknown) — Tue, 13 Jan 2009 03:42:00 +0000

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.

Tips For Buying a First Computer

noreply@blogger.com (Unknown) — Tue, 13 Jan 2009 03:18:00 +0000

The first question you need to ask yourself is why you need a computer and for what purpose you will use it:

* Surfing the Internet
* Sending and receiving e-mail
* Word Processing
* Spreadsheet and Money management
* Listening and recording music
* Storing and manipulating images
* Playing games

When you are certain that you really need a computer then you need to consider what computer to purchase.

The most common type of computer is the PC. Fewer and fewer people these days use Macintoshes and while Apple still makes them they are used primarily for graphics work at the high end multimedia level.

For home or office use you may be far better purchasing a desktop PC with pre-installed software. And PC prices are on the way down.

Of course notebook computers are really great if you want to take advantage of the portability that they offer, although you really need to weigh this against the cost -- as laptops are still much more expensive than your average PC with the same functionality.

You need to determine what capabilities you want your computer to have – the size of the hard drive, the memory and the types of cards – video and audio – that it comes with.

For a standard home or basic office use you should be adequately served by 256Mb of RAM memory with a 80Gb hard drive for storage.

Two other things to consider are that you will need a monitor and software.

For a monitor, try for a 17 inch so that you don’t have to squint to see what is on your screen. Flat panel displays are great for saving space too and the clarity of the displays now are quite impressive.

Most computers will come installed with software. Find what software the PC will come with and work out if this is all you need.

Basic word processing, spreadsheet and email/organizer software is adequate for most people and the ability to access the internet will require a modem installed as well.

If you are worried about learning to use your computer, don't be. There are tutorials within Windows XP to help get you started, and "wizards" are easy to use, step by step programs built into Windows that will help you learn a lot too.

Plus, once you get hooked up and online with your own computer, you will have access to millions of sites ready and willing to help you learn all about your new desktop PC, the software you have, and even learn how to do things you never imagined!

Check out more of our articles on the parts of a computer to help you understand what computer components you need and what you don't before you buy!
