Mine was clean. It's my new POS Compaq I bought on the 26th, with the C drive from my old XP machine installed as a secondary drive. Something like 173,000 files scanned in 77 minutes.
My old machine refused to power up Christmas morning, with two different power supplies, so I bought a $299 POS to get running again quickly. AMD dual core 4800+, 3GB RAM, 320GB hard drive. Doesn't seem markedly faster than the old Intel Prescott Celeron D I was running with 768MB on XP.
