A computer virus attaches itself to a program or file enabling it to spread from one computer to another, leaving infections as it travels.

A worm is similar to a virus by design and is considered to be a sub-class of a virus. Worms spread from computer to computer, but unlike a virus, it has the capability to travel without any human action. A worm takes advantage of file or information transport features on your system, which is what allows it to travel unaided.

The Trojan Horse, at first glance will appear to be useful software but will actually do damage once installed or run on your computer.
