Can't uninstall a program

I've uninstalled more of some stubborn software with it before, and the CCleaner program itself uninstalls clean as well, in my experience. It can also clean up registry entries related to the unwanted programs.

Don't know if CCleaner will eliminate potentially unwanted programs (PUPs) but if you choose to use it beware of another PUP going around that calls itself CC Cleaner that falls into the unwanted, hard to get rid of category.
Usually Google is your friend to find websites that give instructions on eliminating these nuisance programs. They contain links to tools that specialize in killing them off for good.
May I suggest downloading and running Malwarebytes at www.malwarebytes.com to help find and eliminate some of the easier to remove PUPs? I've been using it for a few years now and it's a good tool to have in your toolbox.
