    Best to have a read about it
    Computer viruses range from pesky to outright dangerous. Some just display a message, while others erase your entire hard disk. Clicking on what looks like a harmless e-mail message can lead to hours of recovery efforts, if not irreparable damage.

      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.
