Yance, I need to be honest, but I did not remember you. The forum is so big...
But, sorry for that.
I take your experience as real because a lot of K9 users have avast without problems.
I never had luck with the network drivers in my computer.
Right now, I need to be patient, because both avast team and K9 team promised they're looking into the memory dumps.
Right now, each time I install K9 I got a BSOD, sooner or later.
