I see. Try Ccleaner
, and see if they remain after using it. Make sure you pay attention to what boxes are checked not only on the Windows tab, but also on the Applications tab, as it will wipe out all your internet history and everything unless you tell it not to. (I like to keep my history to find websites than I couldn't find or remember otherwise). Just do not use the Registry cleanup that is built into Ccleaner for reasons mentioned here
But yeah, see if that takes care of it. If not, just don't worry about it.
