A computer worm is a computer program that makes lots of copies of itself, like a computer virus. The main difference between the two is that a computer virus attaches itself to another computer program, but a worm works by itself.

As well as copying itself, a worm can be made to do all sorts of things, like delete files on a computer, or send e-mails to everyone the owner has in their address book
