actually...you just reminded me of what i originally was gonna reply about.

from what ive heard, most of the bigger(more common) virii are written by students who are trying to understand system vulnerabilites and how they are exploited. the thing is you have to think that alot of the stuff students write is never released into the wild...be glad, i bet there are some engenious virii that are just sittin on sombody's pc, never to see the net.
