How to get rid of a internet explorer add on

I have a add-on in internet explorer that I would like to get rid of. When I go in toManage add-ons then I click on more information but the remove button is grayed out! This add-on in call "Internet Program" and it is a pop up add. I can barley see half on my screen do to the amount of adds that come up when I am on the internet explorer. I am on windows 8.1 and have internet explorer 11.

Thanks!
