After AVG warned me of a virus infection, which was promptly handled, each time I try to open any program at all it comes up with an 'open with' box.
I also tried to open REGEDIT.EXE by pressing CTRL-ALT-DEL and opening Task Manager. Once there, I clicked File, then held down the CTRL key and clicked New Task (Run). This opened a Command Prompt window. I entered REGEDIT.EXE and press Enter. This too came up with the open with screen. Even system restore doesn't work. How can I fix this issue?
