How to Disable an Avast Firewall

As a security measure against online threats, Avast Internet Security uses a firewall to monitor incoming and outgoing traffic. It can, however, detect false positives for certain applications and prevent them from accessing the Internet. To make these applications work normally, you can either disable the Avast firewall, or add the applications as exceptions to the Avast firewall.
