I got this error a while ago, i was using a program called HijackThis to remove an annoying browser hijack. All seemed well, but i started noticing after a while that right clicking crashed Explorer.exe in some cases.
These are the situations i have found which causes the crash:
Right clicking an .exe file
Right clicking a shortcut to an .exe file
Selecting a .exe file and hitting delete, ctrl+c or ctrl+x or alt+enter
Selecting an .exe file and hitting the File menu in the window.
Attemting to use the Edit menu to copy or cut an .exe file.
I have tried many things to fix this, but unfortunately system restore was off when this problem occured, so i was left to try and fix it myself. I have used context menu editors to see if there are any errors there, i have also used regedit for this. I have reinstalled windows, i have installed SP2, i have done virus searches and spyware searches.
Does anyone have another solutiong except reformatting? I REALLY don't want to do that of several reasons.
