I’m puzzled on why the instructions I gave you didn’t solved the problem.
Too bad I can’t have a physical look at your system.
I wonder what would happen if everything from avast is removed manually and then perform a real clean installation.

If Jursa (or someone else from avast) contacts you by email with a explanation/(possible) fix, I sure would like to read it.
Ofcourse email is private and I hope Jursa doesn’t mind if you send the content to me in a pm here.

Eddy looks at Jursa…
