Haven't read through the entire thread, but my main and most fervent suggestions would be:
1. Give us the option to turn off the constant update popups.
2. Put the ads/news INSIDE THE GUI. So we see ads when we use the GUI, not popping up in our face.
I know of no other antivirus package that has such huge popups, if any at all, when nothing important had happened - it's just a definition update, I don't need to know every time it happens. And I certainly don't need to know that Facebook has been hacked on top of that notification, so together they take up a third of the vertical screen space. I mean it's simply obnoxious.
I've used Avast for many years, but with those "ads" or "news" or whatever they are, popping up with the already mildly irritating definition updates, I'm at the point where I'm thinking about canning Avast and installing the free MS Security Essentials.
There are many free AV and firewall options out there that don't irritate with constant popups, and certainly not with irrelevant ads and news. If you keep showing people information they don't care about, they will want it to go away altogether. Your advertising is creating negative sentiment - which is the opposite of what advertising should do. In short, you're doing it wrong.
7. I have generally liked the toaster update notifications as they were relatively unobtrusive, but now they are obtrusive, since the introduction of the double height and wider combined auto update/upgrade toaster (which still looks bad). I have dialled the duration right down to 1 sec and I don't think I'm alone in doing that, so its marketing benefit is lost.
Oh no, you're certainly not alone in doing that.

Some people like the constant definition updates, even the sounds (god knows why) but we at least need the *option* to turn off definition update notifications. I'm a fan of Avast, but seriously, popup ads are not acceptable. That is how malware behaves in my book.
Ok, had my popup rant. Now to wait and see if either the popups or Avast itself disappears from my computer.
