How To Allow An App Through Avast Firewall

The Blocked & Allowed apps settings screen allows you to easily manage applications on your PC that are always blocked or always allowed by at least one of the following Avast Antivirus features:

Ransomware Shield
Webcam Shield
Sensitive Data Shield
Password Protection

Refer to the relevant sections in this article to manage your blocked or allowed apps.

Open the Blocked & Allowed apps settings screen

Open Avast Antivirus and go to ☰ Menu ▸ Settings.
Select General ▸ Blocked & Allowed apps.

The Blocked & Allowed apps settings screen shows your List of blocked apps and your List of allowed apps:

Blocked apps: Blocked applications are always prevented from accessing your system. You are not notified when a blocked application attempts to access your system.
Allowed apps: Allowed applications are always able to access your system. You are not notified when an allowed application accesses your system.

Add a blocked or allowed application to your list

If an untrusted application attempts to access your protected folders, webcam, sensitive documents, or passwords, you may receive a notification from Avast asking to block or allow the interaction.

Selecting Block automatically adds the application to your List of blocked apps.
Selecting Allow automatically adds the application to your List of allowed apps.

You can also manually add applications to either list by following the relevant steps below:

Specify which features block or allow a listed application

You can view which Avast features currently block or allow a listed application by checking which icons appear in the Blocked for or Allowed for column:

To change which Avast features block an application:

Hover your cursor over the listed application, then click the … (three dots) icon that appears, and select Change blocked features.
Tick or untick the Avast features that you want to always block access for this application, then click Change.

Your changes are saved and are now visible on the Blocked & Allowed apps settings screen under the Blocked for column.

To change which Avast features allow an application:

Hover your cursor over the listed application, then click the … (three dots) icon that appears, and select Change allowed features.
Tick or untick the Avast features that you want to always allow access for this application, then click Change.

Your changes are saved and are now visible on the Blocked & Allowed apps settings screen under the Allowed for column.

Remove an application from your list

To remove an application from your List of blocked apps or List of allowed apps:

Hover your cursor over the listed application, then click the … (three dots) icon that appears, and select Remove.

The application no longer appears in your List of blocked apps / List of allowed apps. The next time the removed application attempts to access your protected folders, webcam, sensitive documents, or passwords, you receive a notification asking you to block or allow the interaction.
