Can you say exactly where the folder appeared? Desktop? somewhere other than your document folder? Have you recently done an MS update, have auto-update enabled, etc? If it does not trigger an antivirus/spyware alarm, it could be a remnant of an MS update and may be a system folder that you do not have ownership of. If you have XP Pro, you can check this easily. If you have XP Home, you will need to enter safe mode to do so. If you can take ownership of the folder you can do with it as you wish. Good luck.
