Hi!. Sometimes I see a red exclamation mark in the Avast icon on the System Tray, and it's because Avast Firewall disabled. I click on Activate and it's Ok, until sometime it disables again. It seems this happens during some Windows starts, not always.
I manually disabled Windows Firewall and it never became enabled again by itself, so there's no conflict among firewalls. OS is Windows 7 x86. There's no other antivirus, etc. installed.
I've already searched for "firewall" in the Forum but couldn't find a similar case. Any hint will be appreciated!
