Rebooting during virus scan

I am trying to help my friend fix her computer but have run into a problem. She is running ME. Spybot and adaware both run and i have removed all spyware. She did not have an AV program installed however and when ever i try to run on the system will restart. I have tried a bunch of AV programs including AVG, housecall, other online virus scans and DOS virus scans included on the Ultimate Boot CD while booting in DOS. I have also attempted to run installed and online virus scans in SAFE mode. AVAST! does not find anything but every other virus scan results in the system rebooting. Any help would be greatly appreciated. Here is the Hijack this logfile:
