Hi, I posted my issue on the Microsoft Questions website and they identified the issue from Avast.
So I wanted to tell you this, maybe someone will solve the problem with the program, because I have been using it for a long time and it is one of my favorite programs.
In the last month I experienced 14 (fourteen) occurrences of BSOD with Win 11. CAUSE: aswArPot.sys
It happened with Avast free and Opera: just upon exiting Opera.
I tried with other free antivirus and BSOD was not experienced: in a time span of a week only, though.
I uninstalled WIN11 and reinstalled Avast free: after few days the BSOD happen again with the same CAUSE as above.
Grateful for support: I would like to keep both Avast free and Opera.
