Looks like it's time for a fresh install. AVG finds nothing wrong, but I can't finish a scan with Ad-Aware, that program gives me a dll error when I open it, and can't even install Spybot Search & Destroy.

Woo!

At least we have the laptop...

edit: oh, I forgot to mention, it took two hours to struggle through slow folder changes and unresponsiveness to back up my profiles for Firefox and Thunderbird, plus the FFXI User folder...
