Personally I'm have a high tolerance to non-intrusive ads, such as the one here in the UI (marginally better than popups), but I'm using the free version.
It would certainly be a different story if I had paid and had changed the settings so as not to get other product popup offers, only to get them in the UI, where there is no option to disable 'all' ads.
I had two ads today one a popup and the other in the UI, both about the same thing 'Your welcome gift from Avast is ready.' Since I have been using avast free for eleven and a half years, I'm not new, so ads when they arrive really have to be relevant/smarter.
I knew what this gift would be before I even clicked the unpack it button.
