It would seem that your pc has the Backweb software add-on (which is sometimes added by /some/ pc makers , as well as being added for some specific pieces of hardware).
Is your pc from a specific manufacturer? what kind (make) of video card does it have?
But I suppose, more important: Have you made recent changes to Windows settings or the startup programs, changes of any kind? that may coincide with the beginning of "this" problem.
