Thank you Tech, for the honest response

For instance... The non sense of choosing which virus do you want to be protected from?
Well, That's important, some users blame an Antivirus why it does not detect stuff like Proxy etc and if AV detect it some other users blame it because of FPs! That's when you can use Avira configuration for detect or detect a set of files, e.g. SPR (Security Privacy Risk) or Joke/Games etc
Do you mean more or less lately?
Fewer, in last year I had no FPs in my own computer and have seen very very few FPs report outside
I understand how you think of everything else than avast, you don't ignore good features of else, but you have become something like addicted to avast, the way a father love his kid, you look at all goods of avast and even don't feel problems of that, you don't want to ignore, you ignore them unwanted. same goes about me! the way I feel about Avira. You like UI of avast and I love UI of Avira, that's matter of choice, neither is bad or good. You like big and busy interface of avast and I love clean and old style interface of Avira...
I used avast for a long time, since 4.7 and then beta test of 5 and then 6, Thanks VLK I could get IS version for free and played with that, maybe it's not a bad program, just it's not what I like and what I expect from an AV, I want an antivirus to have maximum protection (that's a joke to say that's not a problem if our AV don't detect some malwares!) because its an antivirus not a toy, I want my security software have minimum impact on windows, don't bother me, give high detail on every task and being maximum customizable.
e.g. you asked what I'm missing in avast Firwall, well, Avira firwall is only Firewall, no other stuff in that and very very easy to configure, the way it ask for unknown programs and trust signed program is something unique I've not seen in any other paid firewall, even in top rated standalone firewalls, having easy to add/remove rules per network adapter, being strong enough to avoid any program or virus bypass it, it has only needed protection and no unessential protection. That's just an example and I feel same for every other Avira related stuff.
