Allowing internet access when Avast Firewall blocks a program

 

By default, the Firewall feature in Avast Free Antivirus, Avast Premium Security and Avast One restricts internet access to certain networks and programs. Access may be restricted to public networks and streaming-media programs, network games, or custom business applications that are provided by your employer.

This article explains how to change your Firewall settings to manually allow a network or an application if you know they are safe.

Add a trusted network

Every time you connect to a new network, Avast Firewall detects if the network is private or public, and automatically applies the relevant settings. If Avast Firewall restricts access to your network, you can manually specify that the network is trusted by following the steps below:

We recommend you only modify your network rules if absolutely necessary. In most cases, Firewall formulates optimal rules without your input.
  1. Open Avast Antivirus and go to Protection ▸ Firewall.
  2. Select the Networks tab.
  3. Click Show settings next to the relevant network.
  4. Select I trust this network.

Your network is set to Trusted. When you are connected to a Trusted network, most apps and devices are allowed, because fewer Firewall restrictions are imposed.

Allow internet access to an application

Default application rules are created when an app tries to connect to the internet or to another network for the first time. If Avast Firewall blocks a trusted application, you can manually configure the application rules for your app by following the steps below:

We recommend you only modify your application rules if absolutely necessary. In most cases, Firewall formulates optimal rules without your input.
  1. Open Avast Antivirus and go to Protection ▸ Firewall.
  2. Ensure that the Apps tab is selected, then switch the view to All.
  3. Click Application name to arrange the apps alphabetically.
  4. Find the relevant app on the list, then click ⋮ Options (three dots) ▸ Show app rules.
  5. Click the Trash icon next to all existing rules.
  6. Click Add new rule.
  7. Configure the rule as below:
    1. Enabled: Ensure the slider is green (ON).
    2. Name: Give a name to your new rule.
    3. Action: Choose Allow.
    4. Protocol: Choose All.
    5. Direction: Choose In/Out.
    6. Profile: Choose All.
  8. Click Save.

Each time you use this app, Firewall applies the chosen app rules.
