When I go to access my external hard drive an error message pops up saying "Windows explorer has encountered an error and needs to close" Does anyone know what would cause this. Background: This started after I left my computer unattended for 7-8 hours. I was downloading a Linux distro. I have already restored to a point before the download. I have also scanned for virus/spyware with AVG Pro, ZoneAlarm Pro, Ad-Aware, Windows Defender, and Spy-Bot. This is really frustrating. Any ideas would be appreciated.
