Thank you for the response. I was able to find
"avast settings" => "Sounds" => click on "Diasable Acast sounds."
That was the closest I got to according to your instructions. I did not see the exact menu yu had outlined.
In any case, it has turned off all sounds. However, I only want the blue notification sounds right after the updates turned off. I still want other sounds such as "alarming sound" when there is a possible virus attacking from a website, or if I am running the virus scan, then I want the sound on when it detects any virus informing me of the "catch."
Can you elaborate again exactly how I can ONLY turn off the notification sound and not any other. Thanks again
