I am a network tech and have my own problem it seems.
Research it seems to be as:http://www.bleepingcomputer.com/forums/t/137449/suspected-infection-suspicious-stllssvr-windows-service/
Very weird effect that is the same in both safe mode and regular mode.
Icons and desktop blink on and off up to 3 or 4 times, then you get a blank desktop.
You can push the power button (XP) to shutdown my Dell, but that is it.
If you hurry, you can get on internet or other function. I checked control panel/users for example, and I am still admin, but task manager is locked out. The pattern is the same on a visitor login I have setup (low rights), but I can ctl-alt-del where I cannot on my login. I am seeing weird .exe's running, but stopping them has no effect.
I have run different online scans (Kaspersky, Trend, Nortons (a joke), etc. Each finds and cleans different malware, but it has not effect on my problem. I have Spyware Doctor (updated OK) & AVAST Pro installed.
Need some help on this one, and it is my own! ;-)
