I hate freaking viruses, and I hate "free scanners" that don't work.
Don't use McAfees free virus scanner because it doesn't pick up anything, also don't use Avast's free virus cleaner because all it doesn is install spyware and claim its "deleting viruses" but then you scan with Norton and they are STILL there!
The best FREE scanner I've found is TrendMicro's Housecall scanner. It is a really reliable scanner that even has a free quiz to save 20% off of Trend Micros Internet Security suite. Very good scanner..
