all .exe being opened by notepad

[SlashDK]

I'm running Windows 7 Ultimate 32 bit edition on my PC. For some reason all the .exe files are being opened by notepad. That means I can't open any program at all. Other extensions work fine and thats why I'm being able to open firefox (by using a saved webpage). Is it a virus attack? Please suggest some way to set the default to something that opens .exe files.
