Firewall

Access this feature from: ProtectionFirewall

Firewall monitors all network traffic between your PC and the outside world to protect you from unauthorized communication and intrusions. This feature is designed to require minimal input from you. To ensure you are protected, all you need to do is keep Firewall turned on and, when prompted, select the appropriate Firewall profile for each network that you connect to:

  • Private: if you trust the network (for example, your home network).
  • Public: if the network is publicly shared (for example, the network at a cafe or airport).

These profiles control the settings, which determine how strictly Firewall protects your PC.

Note: Firewall is available in Avast Ultimate and Avast Premium Security only.
