I believe I was infected by a virus not sure exactly which one but the
payload was winupdate which had my CPU at 100%. I was unable to start the
Taskmanager or run CMD or Regedit from the start menu. I started Regedit and
deleted all instances if winupdate, the Task manager now works but I still
cannot run Regedit or the CMD I get the following error
"The NTVDM CPU has encountered an illegal instruction. CS:014b IP:05cf OP:63

Do a more formal scan with some tools. Do the scans in safe mode without
networking. Install, update, reboot, go to safe mode without networking,
scan, clean, reboot, do a "light" scan just to see if that's resolved the
problem. If a tool reports finding something that can't be cleaned then post
back with the specifics and we'll see what we can find for you.

problem solved using Ad-Aware by Lavasoft! it check the registry and neatly
packaged and quarantined the culprits and after deleting them I was in good
standing. My only regret is not saving the log file of the scan to be able
to see what happened
