A little late for a virus scanner if you've already got a virus. Seriously though, are you talking free scanner or do you intend to purchase? If you want to go the free route there is AVG. If you feel like paying, I'd without a doubt, use Norton's virus scanner. What kind of "problems" are you running into that seem abnormal?
See I dunno if I do or not. I DL'd a free one and it did not detect anything.
Sometimes the computer will just stop, not freeup but not respond to anything.
It get under 70% resources most of the time even with 256mb ram and a 16meg AGP vid card. I plan to go to 512mb here soon, maybe a larger vid card, and go dual HD's to run only the OS on the smaller one and all my other stuff on the other.
It does it even after being defraged.
Someone told me I can clean up my "registery" what would that entail?
