OMG I hate that guy.
I got my new pc around april last year and we had been connected to the internet for about a fortnight, when my computer got infected with the sasser worm. Me and my dad spent ages trying to get rid of it but it kept crashing.
We finally got it fixed by changing some internet connections or something, but it wasted so much of my time.
Anyway, I'm glad he admitted to it and i hope he get what he deserves.
