My Cursor is Haunted

[WindSong]

For the last couple of days, my cursor seems to be jumping all over the page.  I can load a new page and it automatically flips to the bottom of the page.  I've had my system scanned at housecalls trend micro and nothing was found.  I run Norton System Works and have never had a problem with that.  Only programs I've downloaded lately have been the new or updated badgehelp autos.  I've cleaned my mouse ball also.  Can anyone suggest what the problem might be?  It seems to have a mind of it's own lately and is driving me nutz!!  If this helps, my system information is:

 ;) Haunted may not be the right word for that LOL, that problem is MOST common in Dell Portables Erratic Mouse Movement, which is simpler portables to fix by installing a driver. But in the 2 yrs I have been certified for Dell Never have i heard of it on a Desktop system but I am curious,, so Im gonna chat with a tech support buddy of mine at dell see if he gives me  quick answer.
