Thank you, I did read that as well and did go into safe mode but still the problem was not solved until I removed Avast-
My Windows 10 is up to date on every aspect, Avast was up to date as well until I removed it.
Since you have no solution and I see that Avast does not really want to go into this discussion, I will try another antivirus and see if this happens, then you will be right which I doubt. I really love avast and it is a pity to change to another antivirus
