What is a virus and how its work
Definition: "A computer program that is designed to replicate itself by copying itself into the other programs stored in a computer. It may be benign or have a negative effect, such as causing a program to operate incorrectly or corrupting a computer's memory."
In this day and age computer security is critical to the optimal health of your PC or laptop. A a lot of security threats get installed on your computer automatically in the background without your permission or even you knowing anything about it.
Did you know that some viruses and spyware programs will scan your computer for passwords or they will log all the keystrokes when you type. This could allow the creator of the malicious software to access your bank accounts, credit cards, email accounts, even your favorite social networking sites like Facebook, Myspace, Twitter, etc.
How a virus act?
A computer virus is a program that can do a great deal of harm to a computer and its files. Each has a particular size and an identifying bit pattern. Antivirus software compares these characteristics of known viruses against each of the files (programs and data) on your computer. Once discovered, the infected file may be disinfected or deleted. Data protection from virus and malwareIt important to understand that a virus must execute on your computer before it can do any damage. Either you or one of your application programs must be tricked into executing it. The simple type of virus comes attached to an innocuous looking email. You may get an email from someone you met last year at a computer graphics convention, for example, with a subject line that says "My latest animation." You seem to remember meeting this person, so you willingly double-click on the attachment. Once it runs on your computer it can do anything you can do, like delete all your files, corrupting all your directory entries, or even sending an email to everyone in your address book with a copy of itself attached! Some virus programs come disguised as macros in word processing or spreadsheet documents, which are given control when the document is opened.
More sophisticated virus programs exist that take advantage of a "bug" in one of your otherwise trustworthy application programs. A programmer notices that an application that many people have on their home computers reads data into a buffer, and that this application doesn't bother to check the size of the data it is reading in. The programmer sends you a data file that exceeds the size of that buffer, overriding some internal function in that application. When the application wants to execute that function, the programmer's code is executed instead, giving it an opportunity to do damage.
Some computer virus programs are harmless, interrupting whatever you were doing to draw some silly image on your screen, for example. But it is best to employ good antivirus protection software, and always keep it and it's virus definitions up to date. There are other virus-like programs. One type lulls you into believing that you are getting a free program.
You think this is some cool plotting program, for example, when it's really a program that lets the programmer take control of your computer through an Internet connection, captures your keystrokes to a file that gets sent to a remote location over the Internet, or just does a lot of damage, like a virus. Such a program is called a Trojan Horse, an allusion to how the Greeks captured Helen of Troy. Some propagate themselves by sending many copies of themselves over a network. These are called worms. But all of these names are just a semantic distinction: these programs are designed to do harm, even if it's only a minor interruption of your work, and the only up side seems to be an inflation of their designer's ego.
Most common question we get is: How did I get this virus or spyware in the first place and how do I keep it from happening again? Most common source of virus infections are emails. A lot of spam emails will include a link to a website, which might even look legitimate, but deep down it has a malicious code included that will secretly install unwanted software on your PC.
Virus removal can be surprisingly tricky. Pernicious and predatory, computer viruses seem to find the most creative and unscrupulous ways onto your pc.

Another way of preventing a spyware or malware installation is to keep your system up to day with the latest software updates. This will include all Microsoft products like Windows XP, Windows Vista, Windows 7 < all Office application. Also make sure to frequently update software like Adobe Acrobat Reader, Adobe Flash, Shockwave or Java.
