AIS firewall

every time I got conneted to the net the firewall pop-up a window~That makes me annoyedCould any one tell me how to deny the windows~~

the only way i see unless im missing it is to go to firewall expert settings and network profiles turn off the auto profile switching this is what switches between the home or work or public setting for your stored network profiles.

…so with this off, then any connections, without a rule set, will just go under the current FW setting and not prompt me to choose as well as the above fix?

Does the PC have 2 network cards?
My experience is that if your PC has more that one enabled network interface (RJ45, USBtoLAN, wireless, etc), the firewall asks for confirmation of the settings for the detected network(s). If the connections are bridged, avast! only "sees’ one connection and so doesn’t advise. (I presumed this was by design.)
