I'd be rather cautious with the 'Stinger' utility actually.

I tried it out on a system which was 'Netsky' infected, and found the (rather general purpose) utility to be quite 'brutal' in its approach.

While it certainly cleaned the infection, the end result was a Windows XP system which had the user locked out of quite a bit of Control Panel's functionality - including Add/Remove Programs, System Properties, Device Manager, and a few other applets!
