Is it a Computer Virus?

A computer virus is a self-replicating computer program that spreads by inserting copies of itself into other executable code or documents.

A computer virus behaves in a way similar to a biological virus, which spreads by inserting itself into living cells.  

While viruses can be intentionally destructive, for example, by destroying data, many other viruses are fairly benign or merely annoying. Some may carry a delayed payload, which is sometimes called a bomb. For example, a virus might display a message on a specific day or wait until it has infected a certain number of hosts. 

• E-mail viruses - An e-mail virus moves around in e-mail messages, and usually replicates itself by automatically mailing itself to dozens of people in the victim's e-mail address book.

• Worms -A worm is a small piece of software that uses computer networks and security holes to replicate itself. A copy of the worm scans the network for another machine that has a specific security hole. It copies itself to the new machine using the security hole, and then starts replicating from there, as well.
