Well to correcty viruses are not created, they are programmed.

Viruses are generally lines of codes written various languages of programs by expert programmer. Once written they are let in the loose to spread on their own.

There are virus creating programs like this one : http://www.megasecurity.org/trojans/t/te...
First, someone has to find a security hole in Windows (let's be honest, you can hardly fart sideways without falling into one). Then a programmer writes a program 鈥?the virus 鈥?to take advantage of that flaw to do something, while doing so in as stealthy a manner as possible and replicating itself. Then they let it loose, and the rest, as they say, is 144,000+ ''pages'' of history.
They are written, like any other computer program.
