Hey, thanks for reaching out. First of all, we really appreciate your support and hope you decide to stick with Avast!
In regards to the popups, this is very easy to control through Settings -> Popups, simply uncheck the box for other product offers and you're all set. Since you have an upgraded version of Avast you can disable this at any time.
In terms of pricing and features, our team has put a lot of time into license options that have a good mix of features and are affordable as well. You might want to take a look at
Avast Ultimate which also bundles in Cleanup Premium, Passwords Premium, and SecureLine VPN (which may save you money!)
Also, generally, I'm happy to answer any questions you have about Avast. Thanks again for your support!
