Mods, due to the nature and serious of this problem I wanted to air it in GC as it would have a wider audience and therefore more of a chance of me getting a solution rather than in the computer forum. Although if it is to be moved then I understand why. Right, onto my problem... the compy has picked up some sort of virus or something or other... basically windows explorer does not run. At all! On the desktop I get my background pic but no icons and no taskbar and the taskbar doesn't respond the the Windows key. I can go to task manager which is what I'm using to use the computer but when I try to run explorer.exe (as it isn't in the process's list) it doesn't run or it runs then shuts down straight away and keeps recycling like that. I've run the usual AVG, Spybot, Ad-Aware and Registry Fix (which has always been brilliant over the last couple of years) and they are all coming up fine. I've just uninstalled AVG and re installed fresh and I'm running the scans again. System Restore back a few days and still no joy, although the problem didn't come about until yesterday afternoon. Any advice and help please folks???
