Make sure your anti virus and anti ad/spy/malware programs are up to date.
Get another ad/spy/malware program. Something like Spybot Search & Distroy. No one program sees all items.
Get crap cleaner. (ccleaner) This handy little tool cleans out the garbage that clogs up your system. Run it over and over until it doesn't pick up any thing.
And I'd not be so sure you got that virus if you had the restore points turned on while you ran the scans. Many nasties hide out in the restore points. When you run your scans they come back from hiding in there and it's back to business. Turn them off then run your scans. Warning> Disabling the restore point will delete them. But when you have a bad infestation you have to shut them off. Otherwise every thing you do is pointless.
Run your scans from safe mode. This mode loads just enough to get running. By not loading every thing the nasties get caught napping and it's bye bye.
As a side note, when you get done with all of the housekeeping chores, defrag. A seriously fraged drive will be the result of all the scans. It just takes a few mins and you will notice the difference in the performance of the system over all.
All the programs I memtioned can be gotten from this link.
Make sure you update every thing you use to scan/clean your system.
And finally don't forget to turn your restore points back on and once you're sure your clean, back up the system.
