As I wrote in my own thread, I suffered from Avast's mistake, too.
To good people making Avast: sorry, guys, but you really *owe* us an explanation. I understand that no program is perfect, other programs suffer from FPs too. But as you see, really a lot of people were affected by Avast's mistake. That really warrants some official comment on your side - only if to say "Sorry, we're not screw up again".
And Polonus - you really can't expect all Avast users to be proficient in computer matters. Heck, I'm not green to those things myself, but I still managed to get fooled by Avast. So, "You should've checked the forum before doing anything" is *not* a right answer.
And BTW. I'd really be helpful if someone adviced me how to get my Internet connection back online...
