How do you use CCleaner's uninstall if the program doesn't show up on the list?
Hi Tom, and welcome to the forum.
In a word you don't. But according to a post I've just read on another forum, there's an option in the Start/All Programs menu entry:- Webroot | Spy Sweeper | Uninstall Spy Sweeper.
Have a look there. CCleaner would use the programs own uninstaller anyway.
EDIT: If you have any problems getting rid of it, post back.
