In simple terms, a computer virus is a malicious program, spread through email and other various applications, that damages your computer. Typical Viruses cause computer sluggishness and damaging your files. It could damage files such as Word documents or games or programs. A virus also duplicates itself onto your computer and onto others on your network. It could damage it very badly by causing the hard drive and RAM to fail.
Fortunately for us, there are programs called Antivirus programs that protect you from viruses. How an antivirus works is that it connects to the company database and sees if a virus in their database matches one in your computer. Good antivirus software usually comes with heuristic detection that matches unknown viruses to one in their database by examining the code. There is no antivirus that will keep your computer 100% safe but most are pretty good. Some great paid software are:
- Trend Micro
- Kaspersky
- BitDefender
- McAfee
Other free ones are:
- AVG Free
- avast! antivirus
- avira antivir

A virus is a piece of malicious software (malware) which is designed to cause damage to your computer system in some way.
The next step up are Worms, which are viruses that like to replicate & spread to others.
If you think of computer viruses like diseases for humans (like the common cold or AIDS), then you can really understand how nasty they can be.

It is code that affects a system by causing eratic or incorrect actions in the computer.
Linux ( Microsoft.com, hotmail.com, msn.com, all of Redmond campus run on over 45,000 Linux computers, so are immune), BSD (Mac and Yahoo.com among others, all run it!), have no virus.
If someone were able to write an automatic malicious program for the MAC or BSD, or Linux, he would be infamous! Needless to say hundreds or thousands, have already tried, and failed!

It opens it up like a picked scab... except it destroys all the "white blood cells" of your computer once it opens it which leaves the computer completely open for fradulent actions by the person responsible for the virus.

It's a vicious software program designed either to drive you crazy or triggered because you went to a site and didn't buy anything. It damages your computer because it lets loose with adware, spyware, a variety of viruses including trojan horses. Things will keep popping up and you can't use your computer normally. It will place itself in your start up and usually if you try to delete them, they come right back. It slows up your machine tremendously. So it's important that you are careful about the sites you go to and what you click on.
That happened to me and I couldn't get rid of all of them and had to erase my C drive and reinstall the entire C drive from scratch.
