For whatever reason when I tried to do a system restore, even if it is for testing purposes, Avast prevented this system restore. So I downloaded the Avast removal tool and was able to do a system restore after the program was totally removed. However, I did not have to remove the program. What I found is that the Avast self defense module was preventing my system restore and by simply unchecking that box, system restore worked without me having to uninstall anything. I hope my research into this can help others.
Thank you.
