I've got an issue with a tower running XP and cannot launch exporer.exe. The system recently had the, what I like to call, FBI virus. The virus was removed and now this issue has come about. I've tried rechanging the shell to explorer.exe as well as the userinit.exe. The issue has still not resolved. Also, I'm getting this error code: entry point_except_handler4_common could not be located in the msvcrt.dll library, and this is titled: explorer.exe - Entry point not found
