Hi, was wondering if anyone could help please, I have a "exinjs" polymorphic worm on my PC & although I can block it from using my net access I can't find anything to get rid of it without fear or wrecking Windows.

Can anyone please advise if there is a virus scanner that can rip this things still beating heart from my PC without killing my system?

Tried Pest Patrol, PC-Cillin, McAffe, AdAware, Zone Alarm Pro.
