That's because its registrey key that points to opening the program was not deleted when you uninstalled the program, so it keeps trying to run it but can't. Some programs, like Windows Messanger are part of your operating system, and will do this to you if not uninstalled properly. Never just delete files, always use the add/remove programs wizard in your control panel. Try running a clean up utility like CCleaner http://www.ccleaner.com/
