Name a major difference between the ways a worm is spread and a virus is spread.

Answer: A virus is a program that gets onto a computer without a user's knowledge and then performs an action that can range from mischievous to destructive. For a virus to be spread, there has to be some kind of contact between an infected user and another user - generally, that contact is the forwarding of an email that has an attachment that contains a virus.

A worm is a type of virus, but a worm can spread on its own without any "help" from the infected host. Even worse, a worm can replicate on its own, resulting in many more worms attacking other hosts.
