By default, the firewall performs a series of checks to try and determine if a network is Public or Private. A home network is an example of a Private network, while a coffee shop's Wi-Fi network is an example of a Public network.
To change the firewall’s configuration or disable it, open Avast Free Antivirus or Premium Security.
On the left navigation bar, select Protection.
Next, click the Firewall button to bring up the configuration page as shown below:
Here, you can disable the firewall entirely by clicking on the green slider next to “Firewall”.
When you do this, you will be asked how long you want the firewall to be turned off.
After you select how long you want it to be turned off, you’ll be asked to confirm that you want to turn it off. This is a security feature meant to ensure that the firewall is not being turned off by mistake or by malware.
Once the firewall is turned off, you’ll see it disabled in the configuration panel.
You can easily re-enable the firewall by clicking the red slider.
The firewall differentiates between Trusted and Untrusted networks. It has greater security on Untrusted Networks, but that can make it more difficult to connect to other devices on the network. The firewall has less security on Trusted Networks but can more easily connect to other devices such as printers, speakers, and smart home devices among others.. As noted before, you should only mark a network as a Trusted Network if this is your own network or the network of someone you trust like a family member or friend.
To change a network from Trusted to Untrusted or vice-versa click Show Settings to the right of the network.
You can configure the firewall to block on a per-application basis. To do this, click on Apps. This will bring up the Application panel and you can click Block to the right of the application you want to block.
To see the firewall logs, click on Logs which will bring up the firewall log listing.
