I'm not being defensive, I'm just an avast user like yourself with no affiliation or sway over Alwil software or OA developers. I was simply pointing out that there has been an OA update which is supposed to resolve an issue it had with the web shield.
There are also many topics relating to how to ensure OA allows avast's updated on the reboot, such as putting it into learning mode (was one suggestion), so the potential solutions are out there, to stop OA blocking changed components of avast without any pop-up notification on a changed component, so this wouldn't just happen with avast but other program updates if they become active on boot or connect to the internet, etc.
Which is why I suggested continuing in another topic so as not to drive this one off-topic not an attempt to silence you or be defensive.
