A client's PC keeps popping up this error whenever I try to browse file folders, or install applications. This issue does not occur in safe mode. PC is running Windows XP Professional on SP3. I first issue I found on the PC was that McAfee was completely corrupted, I.e. upon startup, clicking on the tray icon yielded a white square where the McAfee interface would normally display, and the application would not load at all. There was also a pop up that McAfee Service Host has encountered a problem and needs to close. I assumed somehow the installation had corrupted and tried to uninstall the application, however, ran into the explorer issue. Further investigation found there was a kavo item being triggered during startup. After following instructions online to remove all traces of the worm, I also ran the McAfee software removal tool to uninstall McAfee (note all this could only take place in safe mode). As of now, I'm left with the explorer.exe issue, which I still am unable to resolve. Any help would be greatly appreciated. Thank you.
