Avast Firewall is the only part of the Avast superior products, i.e., Avast Premier and Avast Internet security. We do not recommend using Windows Firewall over Avast Firewall. But sometimes you may require to pause it or turn it off for one reason or another, especially when it is blocking access to some sites and applications you trust or if you have any other third party Firewall, for instance, Comodo Free Avast Firewall. Avast Firewall is an important feature, which protects you from threats and hacker attacks.
