That's is precisely the problem, you can't design a UI to suit all users, so at best it is going to be a compromise.
I don't particularly like this UI (like many others) lots of things are buried deep into the UI and trying to cater for all users paid and free into one UI is never going to be intuitive.
Hell for ages we have been asking for the right click (context) menu of the avast tray icon to be modified to provide more/easier access to commonly used areas. We are still waiting for that and it is something avast said would be looked at. Well it looks like they are still looking, not doing.
