I guess I wasn't too clear in what I wrote. I meant (tongue in cheek) that he should have reprogammed the infected machine's bot to download a firewall to protect that PC. It's just a step up from the bot downloading a newer version of itself. That might alert the owner's that their machines were infected.

I've been a little worried about that scenario as well. I guess if you could show it was a DOS attack, they shouldn't charge you and they should be responsible for blocking it for you.
