What Is the Avast Firewall and How Does it Work?
Avast firewall is a component of the Avast antivirus programme that guards against online threats by tracking and managing network traffic to and from your computer. It builds a virtual wall that prevents unauthorised users from accessing the computer while permitting allowed traffic.
The Avast firewall uses various technologies to keep your computer safe, including application rules, network profiles, and packet inspection. With application rules, you can set specific permissions for each application, deciding which can access the internet and which can’t. The network profiles allow you to define different levels of security for different types of networks, such as public, private, or work. Finally, packet inspection is a technology that analyses the data packets that pass through the firewall and blocks any suspicious ones that may contain malware or viruses.

|---|---|---|
| Protection level | Individual device | Entire network |
| Configuration complexity | Moderate | Varies by router model |
| Programme-specific rules | Yes | Limited |
| Protection from internal threats | Yes | No |
| Protection from external threats | Yes | Yes |
Benefits of Using Both Firewalls Together
For optimal security, using both Avast Firewall and your router’s built-in firewall provides a layered defence:
- The router firewall blocks malicious traffic from entering your network.
- The Avast firewall provides granular control over application access.
- Dual protection safeguards against different types of threats.
- If one system fails, the other continues protecting your devices.
When to Prioritise Router Firewall Settings
Router firewall configuration is particularly important when:
- Securing multiple devices on your network.
- Setting up parental controls across your household.
- Creating guest network access with limited permissions.
- Implementing network-wide rules for all connected devices.
Remember that properly configured firewalls at both the router and device levels provide the strongest security posture for your digital life.
How to Allow Apps Through Any Firewall
While this guide focuses on Avast Firewall, the general process for allowing applications through most firewalls follows similar principles:
- Open the firewall settings in your security software or operating system.
- Look for options like “Rules,” “Exceptions,” or “Allowed Programmes.”
- Add a new rule or exception.
