Avast firewall is a robust security feature designed to protect your computer from unauthorized access and malicious activities. While it provides excellent protection, it may sometimes block legitimate applications from accessing the internet or functioning properly. In such cases, you need to allow these apps through the Avast firewall to ensure they work seamlessly. In this article, we will delve into the process of allowing apps through Avast firewall, exploring the reasons why you might need to do so, and providing a step-by-step guide on how to configure your Avast firewall settings.
Understanding Avast Firewall
Avast firewall is a component of the Avast antivirus software, which is designed to monitor and control incoming and outgoing network traffic based on predetermined security rules. Its primary function is to prevent unauthorized access to your computer, protecting you from hackers, malware, and other online threats. The firewall achieves this by blocking or restricting certain types of network traffic, which can sometimes include traffic from legitimate applications.
Why Allow Apps Through Avast Firewall?
There are several reasons why you might need to allow apps through the Avast firewall. Legitimate applications may require internet access to function properly, and if they are blocked by the firewall, they may not work as intended. For instance, video conferencing software, online gaming platforms, and cloud storage services often require access to the internet to provide their full range of features. By allowing these apps through the Avast firewall, you can ensure they operate without any restrictions.
Another reason to allow apps through the firewall is to resolve connectivity issues. If an application is unable to connect to the internet due to the firewall, allowing it through can resolve the issue and enable the app to connect successfully. This is particularly important for applications that rely on real-time data or synchronization with remote servers.
Identifying Blocked Apps
Before you can allow an app through the Avast firewall, you need to identify which apps are being blocked. You can do this by checking the Avast firewall logs or notifications. When an app is blocked, Avast typically displays a notification informing you of the blockage. You can also check the firewall logs to see which applications have been blocked and why.
Allowing Apps Through Avast Firewall
Allowing apps through the Avast firewall is a straightforward process that involves configuring the firewall settings to permit specific applications to access the internet. Here is a step-by-step guide on how to do it:
To allow an app through the Avast firewall, follow these steps:

- Select “Firewall” from the protection options.
- In the firewall settings, click on “Applications” or “Allowed applications” depending on your Avast version.
- Click on the “New application rule” or “Add application” button.
- Browse to the location of the executable file of the application you want to allow and select it.
- Choose the network type for which you want to allow the application (public, private, or both).
- Set the action to “Allow” for the selected application.
- Click “OK” to save the new rule.
Configuring Advanced Firewall Settings
In addition to allowing specific applications, you can also configure advanced firewall settings to customize the level of protection and access for different applications. This includes setting up port forwarding rules to allow incoming traffic on specific ports, configuring DNS settings to restrict access to certain domains, and setting up network profiles to apply different firewall rules based on the network you are connected to.
Port Forwarding Rules
Port forwarding rules allow you to specify which ports on your computer should be open to incoming traffic. This is useful for applications that require incoming connections, such as servers or online gaming platforms. To set up a port forwarding rule, you need to specify the port number, protocol (TCP or UDP), and the application that should receive the incoming traffic.
Configuring DNS Settings
Configuring DNS settings allows you to restrict access to certain domains or websites. This can be useful for blocking malicious websites or restricting access to certain online services. To configure DNS settings, you need to specify the domain or website you want to block or allow and set the action to “Block” or “Allow” accordingly.
Best Practices for Configuring Avast Firewall
When configuring the Avast firewall, it is essential to follow best practices to ensure you are getting the most out of the feature while minimizing potential risks. Here are some best practices to keep in mind:
Always allow applications through the firewall explicitly, rather than disabling the firewall entirely. This ensures that only authorized applications can access the internet, reducing the risk of malicious activity.
Regularly review and update your firewall rules to ensure they are still relevant and effective. This includes removing rules for applications that are no longer in use and updating rules for applications that have changed their network requirements.
Use strong passwords and authentication to protect access to your firewall settings and ensure that only authorized users can make changes to the configuration.
By following these best practices and configuring your Avast firewall settings carefully, you can ensure that your computer is protected from unauthorized access and malicious activity while still allowing legitimate applications to function properly.
In conclusion, allowing apps through the Avast firewall is a necessary step to ensure that legitimate applications can access the internet and function properly. By understanding how the Avast firewall works, identifying blocked apps, and configuring the firewall settings to allow specific applications, you can strike a balance between security and functionality. Remember to follow best practices for configuring the Avast firewall to minimize potential risks and ensure your computer remains protected from online threats.
What is Avast Firewall and how does it work?
Avast Firewall is a security feature that comes with the Avast antivirus software.
