Just trying to determine if I should have both the Avast and Windows Firewall running. They are at the moment however I noted in the Windows Action Centre that it states both are running and that 2 or more operating at the same time may cause confliction. Windows Defender is turned off. I also have MBAM Pro running real time as well.
In your case the avast firewall was designed to be compatible with the win7 firewall enabled. So you can have them both enabled, essentially what the win7 caters for are Ivp6 IP addresses (not to widely used at present).
