Avast won't remove AppEnable

I have attempted several times to remove AppEnable from my Chrome browser using browser cleanup. It was listed on there twice and it removed it once then would not remove it a second time. I’m still having issues such as pop ups and random tab openings from the application. I tried re-installing AVAST and it updated the system, but it still says “An unknown error has occurred” when I attempt to remove AppEnable.
