To drive the point home: I just got a center screen popup, asking me if I know about tech support scams. The full Avast GUI popped up over everything else, front and center, with this #$#$
This is why many people run in silent mode, and missing actual alerts. Because the upsell is getting way to aggressive and intrusive. I'd go back to silent mode too if I didn't constantly have to check what Avast is doing to my exceptions etc.
Paying would solve this NagWare issue. Maybe. Not so sure after reading the forums for years now. But paying just to turn off the nags, and not getting any other functionality I want or need, seems like a bad deal. What I want, and might pay for, is basic AV that actually works properly. Tested. Without shenanigans.
