Computer Virus Definition: 
A computer virus is a program or piece of code that is loaded onto your computer without your knowledge and runs against your wishes.

A simple virus that can make a copy of itself over and over again is relatively easy to produce. Even such a simple virus is dangerous because it will quickly use all available memory and bring the system to a halt.

Some people distinguish between general viruses and worms. 

•  A worm is a special type of virus that can replicate itself and use memory, but cannot attach itself to other programs.
• A Trojan horses @ Trojan can make copies of themselves, steal information, or harm their host computer systems.
