Every so often Avast will give me a message that I have a bad add0on called Retrogramer. It asks if I want it removed, and I allow it. Then I check for it in my program list and it shows still there. I try to uninstall it and it says it is not there, even though it is still on the list. Then at some random time later, I will get the message again saying I have the bad add-on again.
