You're welcome.
I have been using avast free for over 16 years and for the most part the default settings have sufficed for the average user. But now things are getting more complex, especially for those using the Premium and Ultimate paid versions of Avast. Add to that the UI has become more difficult to use, find things.
I would guess you don't know about the geek:area, a hidden area of the UI, open the Settings and click the Search, type geek:area and see what is there. I have been banging on about the UI and especially this undocumented, hidden area for some considerable time.
EDIT: You could use the About Avast screen, Submit Feedback to suggest a PDF.
