My friend accidentally downloaded a virus, which changed all .EXE files to be recognized as windows media files. Ok, we tried open as, but that doesn't pop up for .EXE files, we tried changing default program used to open .EXE files, which the virus blocked, so we can't tick or untick these. We tried the advanced boot screen, which for some reason he didn't have "Repair you computer" in the screen, which really frustrated me, he didn't even have the "Last know good configuration option"! We tried getting into the registry, but that didn't even work since it was recognized as a media file. If anyone can help me fix his problem, it would be extremely appreciated.
