Not that this helps you much, but I had the exact same problem running adaware on a friend's computer this past weekend...I never did get the darn thing to finish removing/quarantining the files. It found over 170 spyware files.

I ended up running Spybot instead...did the job, but not 100% like when combined with adaware.
It was an Compaq Presario 5000 with dual OS's installed (by mistake)...ME on C, XP on D...the computer had a ton of other problems though, so I wasn't suprised when adaware locked up over and over.
