At this point the PC is stable. I dumped McAfee which allowed enough space to run VundoFix (found nothing) and AVG. AVG made the biggest difference restoring the HD to about 1/3 full which is where I remember it to have been. The remaining problems are a pop-up saying Windows can't find logon.exe after each start, and IE pop-ups that say the system has a virus with an offer to download security software. I'm running Ad-Aware now. Will run Malware Bytes next.

Thanks!
