I installed a screen saver, I want it deleted, went to change/remove, but it won't work. got a pop up asking if I want it removed, I click ok, but nothing.
Well, run Malwarebytes. You probably downloaded the program from one of those popups or banners because you thought they look cool, sometimes those are bad.
Look in C:\Windows\system32 and do a search for .scr that will bring up all the screensaver files that exist on the computer if it is not in there you are looking at a virus.
Sometimes it can remove them from the Control Panel but will not remove the .scr file that can be hidden inside.
It looks like adware. I would use malware anti-bytes to remove it. Go here http://www.techsrt.com/Remove_Viruses.html to download it and it has other utilities that can help you. Another thing to try is google windows installer clean up. This is a microsoft utility that will show you all the programs installed in your computer and you can basically "yank" that program out of your computer. This has helped me a lot when the "add/remove" feature in windows doesn't work so well.
