Timeline of notable computer viruses and worms Early academic work on self-replicating programs[ edit ] The first academic work on the theory of self-replicating computer programs  was done in by John von Neumann who gave lectures at the University of Illinois about the "Theory and Organization of Complicated Automata ".
Some can wipe out the information on a hard drive, tie up traffic on a computer network for hours, turn an innocent machine into a zombie and replicate and send themselves to other computers. If you've never had a machine fall victim to a computer virus, you may wonder what the fuss is about.
Computer viruses are just one kind of online threat, but they're arguably the best known of the bunch. Computer viruses have been around for many years. In fact, ina scientist named John von Neumann theorized that a self-replicated program was possible [source: The computer industry wasn't even a decade old, and already someone had figured out how to throw a monkey wrench into the figurative gears.
But it took a few decades before programmers known as hackers began to build computer viruses.
While some pranksters created virus-like programs for large computer systems, it was really the introduction of the personal computer that brought computer viruses to the public's attention.
A doctoral student named Fred Cohen was the first to describe self-replicating programs designed to modify computers as viruses. The name has stuck ever since.
A hacker would save the virus to disks and then distribute the disks to other people. It wasn't until modems became common that virus transmission became a real problem. Today when we think of a computer virus, we usually imagine something that transmits itself via the Internet.
It might infect computers through e-mail messages or corrupted Web links. Programs like these can spread much faster than the earliest computer viruses. We're going to take a look at 10 of the worst computer viruses to cripple a computer system.

The compilation of a unified list of computer viruses is made difficult because of naming. To aid the fight against computer viruses and other types of malicious software, many security advisory organizations and developers of anti-virus software compile and publish lists of viruses.
