Hi RSVP,
we launched a new product for Mac last month - Avast Cleanup Pro. The mentioned popup is a promotion of the product to our free AV users. So far there is no way how to turn the popup off(we’ll consider it). But we show it only once a month if there is something to clean on your computer (keeping your Mac clean will help to not trigger it ;))
The new product cleans clutter from your Mac, of course. Log files, caches, trash etc. We plan to add more and more features in near future.
I understand that the it may seem confusing - a popup from nowhere. It has Avast logo but you are right that the call to action button might be improved e.g. “More details” instead of “Resolve”. And Google doesn’t know about it because ithe promotion was launched last week.
Thanks for sharing your experience with us!
Lukas
PS: Eddy+Pondus have provided a way how to complain about the phone support already…
