I've seen other threads about a similar or same problem but haven't managed to fix mine. I'm not convinced it's a nasty.

Symptoms: Control panel, IE, My Computer, Windows Explorer, and folders cannot be opened or browsed. Clicking (or double clicking) results in the desktop clearing then refreshing without opening the selected item.

Other Behavior: I managed to find a System Restore point that would fix the problem but... When using Fast User Switching to logon a second user the problem reappears. The problem does not show up if the first user is logged off, only if they are disconnected. I duplicated this several times but am now unable to use that Restore point (or earlier) anymore :rolleyes:.

Spybot and Adaware found nothing but cookies (deleted). PCcillin and Ewdio found nothing. Also checked system files.

Getting ready to reformat but really don't want to...I'd rather sleep at night than mess with my machines.

I looks like I solved it. By using a utility I found here: http://www.helpwithwindows.com/techfiles/explorer-crashes.html. I located something called sstqq.dll in my system32 folder along with several CLSID references to it. Luckily, I have a multiboot setup so was able to use an alternate XP installation to deal with the offender.

Everything seems good now but I wonder why this wasn't picked up by any of the nastyfinders. Apparently there are versions of this thing that can do some very nasty things. I'm still a bit worried about what may have been done.

Any comments about sstqq.dll?
