In my opinion it is something that in Avast Free should be removed.
Advertising and push to sell can be done in another way, but so tired of pop-ups users switch to other providers.
I don't see how it can be otherwise except that you don't understand the principle of advertising as said by Asyn (#5)
Compared to TV advertising, you wouldn't like it to cut your program in half (it's true that it's annoying too
) and the broadcaster to take it out of your way and let you see it for example by pressing the info button on your remote control?
No!!! That's not how it works . If the spots annoy me, I'm not going to ask the channel to remove or to hide them (I know they won't), I'll change channels.
So you're right about one thing, if avast popups bother you, get another antivirus if you think that's the solution.
You're also partly right when you say that other free products have slightly less aggressive advertising, but these may be just appearances, they may have other less obvious ways of annoying you, but they always end up achieving their goals
Moreover, speaking of antivirus, there are not tons of them that are offered for free and even less that do not offer boring ads.
