Possible Virus

Dell / Latitude d620...
February 10, 2009 at 19:52:24
Specs: Windows XP, 2 gigabytes
When my computer is idle for several minutes (maybe 10 or 15), a Windows login screen appears with the caption "Unlock Computer" and a message to the effect that only I or an administrator can unlock the computer. Responding makes it go away and all is ok until the next time. Note that the computer IS NOT coming out of a power save mode - it has been on all of the time. I have run virus scans, registry fixers, and a trojan finder with no resolution. This problem appeared rather suddenly within the last few days. I suspect a virus, but so far no damage has been done and the computer is operating normally otherwise.

Any ideas?

First of all, NEVER respond to those pop-ups, I would say you ignited a trojan of some sort.

You never listed what scans you have done so it is hard to figure out what to suggest.
More info would be great

Thanks for responding.

There was no way to continue working without responding - the desktop and task bar were gone.

Here is what I have tried so far:

RegCure
McAffee Virus Scan
Spyware Doctor
TaskManager
Trojan Remover
MalewareRemovalBot ( found a lot of stuff the others missed) Ran this based on another post in this forum

I have re-run all of the scans with the latest updates. The problem has now disappeared as mysteriously as it had appeared. So I can't identify what caused it. WIll keep my fingers crossed that it is gone forever.

Thanks to all who responded with suggestions.
