COMPUTER VIRUS CONCEPT

Types of Computer Virus •Trojan / Trojan Horse – Back Orifice

A Trojan or Trojan Horse is a program that appears legitimate, but performs some malicious and illicit activity when it is run.

•Worm – Red Code

A worm is a program that spreads over network. Unlike a virus, worm does not attach itself to a host program. It uses up the computer resources, modifies system settings and eventually puts the system down.

Worms are very similar to viruses in that they are computer programs that replicate themselves. The difference is that unlike viruses, worms exist as a separate small piece of code. They do not attach themselves to other files or programs.
