Oh dear.

I have viruses. They're in some files that I want to keep.
Basically, my strategy is reformatting and deleting chunks of the data I've backed up, then moving it back on in the hopes that it's free of viruses. Then I found this place, and figured if you guys can help me, then that'd be nice too.
I've tried moving the data over then scanning it, nothing is ever found, but days later I find my computer infested with viruses.
Should I just go for a full reformat? Can anyone give any advice? I've had some very knowledgeable people trying to help me with this, and I've had them spend hours, only to tell me everything is finally clean...and then I get more viruses in the next few days. I've had clean HiJackThis logs, and still they come back. Avast never finds them it seems until they start trying to do damage...
So I'm kinda in the mindset that no one can actually help me. As I said I've spent hours on this...so if you really think you can then please do
