Armed only with this and no story of the events leading up to this I'll write I would be scanning with EWIDO, Housecall even if system restore didn't help.
I'm using WinXP Pro (SP2). Received the following error message when I try to open an drive (C or D) or any Folder:
Microsoft C++ Runtime Library:
Runtime error! Program c:\windows\explorer.exe abnomal program termination.
Check the Microsoft Knowledge base but could not find any solution to it, can any one help to Hot Fix this error?
