Hi there,

In one simple line i would say that it's also a software program created by some smart programmers to mess up other computer programs. Good luck & Take care.

From Wiki:

In computer security technology, a virus is a self-replicating program that spreads by inserting copies of itself into other executable code or documents (for a complete definition: see below). Thus, a computer virus behaves in a way similar to a biological virus, which spreads by inserting itself into living cells. Extending the analogy, the insertion of the virus into a program is termed infection, and the infected file (or executable code that is not part of a file) is called a host.
