OS: Win XP Media
Symptoms: Explorer.exe shuts down for about 7 seconds, then reappears for about 10 seconds. The cycle repeats. While Explorer.exe is shut down, my Start button, task bar and desktop disappear. If I have a Windows Explorer window open, it closes when Explorer.exe shuts down and does not reappear. This makes it very difficult to navigate to files unless you have a shortcut to a file or folder on your desktop and can navigate to that very quickly.
The problem, I think, is in two DLL files: xxyvwwx.dll and ddcyw.dll.
Both are inaccessible when in Safe Mode. I've run HijackThis, VundoFix and ComboFix. I've run them in Regular Mode and in Safe Mode. HJT identifies the files and purports to get rid of them, but they regenerate.
Any help would be greatly appreciated.
Here's Hijack This log:
