VIRUSES, WORMS AND TROJAN

Virus is used as a genetic term for malicious programs which spread from one computer to another which ordered to corrupt or destroy data. More specifically a virus spread by attaching itself to a normal program file, and will only be executed or propagated when the users take some action.

Worm is a program or algorithm that replicates itself over a computer network and usually performs malicious actions, such as using up the computer's resources and possibly shutting the system down. The most significant difference between a virus and worm is that worms does not need a host as viruses need a host to multiply.

Trojan is a destructive program that masquerades as a benign application. Unlike viruses and worms, Trojan horse do not replicate themselves but they can be just as destructive. One of the most insidious type of Trojan horse is a program that claims to rid your computer of viruses but instead introduces viruses onto your computer.
