I have a computer that I'm working that was brought in for pop-up problems. I went through the system and removed everything that was found to be related to malware. I used Norton Antivirus Corporate Edition and HouseCall from Trend Micro to remove viruses and it found some and were deleted. Now whenever I click on the Control Panel from the Start Menu, it comes up with the little flashlight icon (meaning it's searching for the Control Panel icons) then closes along with explorer.exe, then after 2-3 seconds explorer reloads. Nothing in Task Manager shows up that's suspicious. Has anyone had this problem before? Any idea on how to fix it?
