Download Stinger from McAfee and see if that clears up your problem. It can be ran directly from a CD or where ever you download it to. Just Type in McAfee Stinger into any search engine.
or just click

This isn't virus protection, it's virus removal after you're infected. It looks for a select nasty bunch of viruses. Hopefully the one you're infected with is one that Stinger is designed to find and kill. If so, you'll be back up and running in no time. It's saved my rear on many computers that had been infected with Norton. BTW, I rebuild about at least a computer ever month or two at most from friends and co-workers (home machines) Every one that was infected had Norton on it. Norton only updates dat files once a week, and that's kind of stupid since there's like 200 or so new variations of viruses out each day (or some crazy number like that) Only makes sense, that if you're running Norton, you're probably gonna get infected sometime on down the road. It's still the old FORD/CHEVY/DODGE debate, and personal preference. But I've been running my Jeep (McAfee) for over 4 years now and never been infected...Got it on 3 machines at home and she never skips a beat...knock on wood
haha
Lemme know if that doesn't fix your problem. If not I can walk you through a manual way of finding the little nasty bugger. It'll involve looking at some key places in your registry (where it tells the malware to fire up on boot)
