I found if I download games or similiar items, I occasionally get annoying things like that added to the program , though not the one you mentioned, if it is something you really don't want, go into the "my computer" section, then go into add/delete programs and see if that file has been added, if it is there you may have to restart your computer after hitting the delete button. I hope this helps. if not good luck and let me know if you find another way to fix, I am not a guru by any means just someone who has a terminal case of trying to wreak my own computer then I cry for my fiance who is a guru

Good Luck
Anna
