Hello thank you for your reply.

I do not if I did a roll back right after but I will tell you what I have tried up to now.

I deleated ADVANCE WINDOWS CARE

I deleated Avast
I have reinstalled Avast and had problems updating it still
then A few hours ago I did a rool back then I had 2 Avast installations on my disk
I finally was able to remove them both and installed a brand new copy of Avast.

I do not know if this time it works cause I did not yet have a update window pupping-up

Do you know what could have caused this???
Thanks you
