I attempted to run all three online scans that you suggested. All crashed the system. Panda seemed to run the longest, or at least scanned the most files before the system went down. It indicated three spyware infections before the system crashed. I've not been able to detect a specific file causing a crash.
I've run SE Adaware and Spybot since running the Panda Scan, but no spyware was detected by either of these programs. Running them did not cause a crash.
As an FYI, I have the system power settings at always on, just in case it was mistakenly going into hibernation or automatic power down. The screen saver is also off, also "just in case" of any possible conflict.
