In today’s interconnected world, the importance of cybersecurity cannot be overstated. With the increasing number of online threats, including hackers, malware, and viruses, it is crucial to have a reliable firewall in place to protect your computer. While Windows 10 comes with its built-in firewall, many users opt for third-party solutions like Avast, one of the most popular antivirus programs. Avast offers a range of powerful security tools, including an advanced firewall that helps protect your system from various online threats.
This article will guide you through the process of turning on the Avast firewall on Windows 10, providing detailed instructions, troubleshooting tips, and explanations to ensure you have a secure and well-protected system.

1. Why Use Avast Firewall on Windows 10?
Before we dive into the process of turning on the Avast firewall, it’s important to understand why you might choose to use it instead of the default Windows firewall. Avast Firewall is designed to offer advanced protection against online threats, providing more granular control over your network traffic and better monitoring of incoming and outgoing connections.
While Windows Firewall does offer basic protection, Avast Firewall provides additional features, such as the ability to monitor applications, track suspicious network activity, and create custom rules for specific applications or network zones. These enhanced features help provide a higher level of protection for your computer, particularly if you engage in activities that involve sensitive data or use multiple devices on your network.
By enabling Avast Firewall, you can significantly reduce the chances of your device being compromised by online threats.
2. Installing Avast Antivirus on Windows 10
Before you can use the Avast firewall, you must have Avast Antivirus installed on your Windows 10 system. If you haven’t already installed Avast, here’s how you can do it:
Step 1: Download Avast Antivirus
- Go to the official Avast website (www.avast.com).
- Click on the “Free Download” button to download the installation file.
- Once the download is complete, locate the setup file in your Downloads folder and double-click it to begin the installation process.
Step 2: Install Avast Antivirus
- Follow the on-screen instructions to complete the installation.
- During the installation, you may be prompted to disable Windows Defender temporarily. Avast will automatically take over as your primary antivirus and security software.
- Once the installation is complete, restart your system if prompted.
Step 3: Activate Avast
- After installation, open Avast from your desktop or start menu.
- If you purchased Avast Premium, enter your activation code to unlock premium features. If you’re using the free version, Avast will automatically be activated with the basic features.
Once Avast is installed and activated, you can proceed to enable the Avast firewall.
3. Turning on Avast Firewall from the Avast User Interface
Now that Avast is installed, let’s go through the steps to enable the firewall through the Avast user interface. The process is simple and quick, ensuring that your system is adequately protected by Avast’s advanced firewall.
Step 1: Open Avast Antivirus
- Double-click the Avast icon in your system tray (the bottom-right corner of your screen).
- Alternatively, you can open Avast by clicking on the Start menu and typing “Avast” in the search bar, then selecting it from the list of results.
Step 2: Navigate to the Firewall Settings
Once the Avast interface is open:
- In the main Avast window, click on the “Protection” tab located in the left-hand menu.
- Under the Protection section, click on “Firewall.” This will take you to the firewall settings page.
Step 3: Enable the Firewall
In the Firewall section, you will see an option to enable or disable the firewall. If the firewall is turned off, click on the “Enable” button.
- If Avast Firewall is already turned on, the option will read as “Disable,” confirming that the firewall is active.
- If you have the Avast Premium version, you will also see additional options to configure your firewall settings, such as network profiles (Home, Public, and Work networks) and advanced rules.
Once the firewall is enabled, Avast will start monitoring your network traffic, blocking potential threats and providing real-time protection.
4. Customising Avast Firewall Settings
While turning on Avast Firewall is a straightforward process, you may want to customise its settings for optimal protection. Avast provides several options that allow you to configure the firewall to suit your needs, whether you’re at home, work, or using a public network.
Step 1: Access Advanced Settings
- In the Avast Firewall settings page, click on “Settings” in the bottom-left corner. This will open the advanced configuration options for the firewall.
Step 2: Configure Network Profiles
Avast Firewall allows you to set different profiles based on the type of network you’re connected to. Each profile has different rules for traffic and security:
- Private (Home) Network: This profile allows you to trust devices on your home network and allows for easier sharing of files and printers.
- Public Network: This profile is more restrictive, ensuring that your computer is shielded from outside devices when you connect to public networks (e.g., coffee shops or airports).
- Work Network: This profile is used for workplace environments and offers a balanced level of security.
To customise these profiles, click on the profile name (e.g., Private), and you can adjust the rules to fit your needs. For example, you can allow certain applications to bypass the firewall or restrict access to specific ports.
Step 3: Set Application Rules
One of the most useful features of Avast Firewall is the ability to set custom rules for individual applications. This allows you to specify which applications can access the internet and which ones are blocked.
To create application rules:
- Go to the “Application Rules” section in the Avast Firewall settings.
- Here, you will see a list of applications that have been monitored by Avast.
- You can either add a new application by clicking the “Add” button or edit the existing rules for a particular application by clicking on its entry.
- For each application, you can define whether it is allowed, blocked, or restricted from accessing the internet.
Step 4: Monitor Network Activity
Avast Firewall also allows you to monitor network activity in real time. This feature enables you to see which applications and services are currently accessing the network and whether there are any suspicious activities.
To view the network activity:
- Click on the “Firewall” tab in Avast.
- Select the “Traffic” or “Logs” section to view real-time logs of inbound and outbound traffic.
This can be helpful if you want to track network performance or investigate potential issues with network access.
5. Troubleshooting Avast Firewall Issues
While Avast Firewall is generally reliable, some users may encounter issues that prevent it from working correctly. Here are some common problems and how to fix them:
Problem 1: Avast Firewall Not Turning On
If Avast Firewall is not turning on, try the following steps:
- Check for Conflicting Software: Ensure that no other firewall or antivirus software is running on your system. Conflicting programs can prevent Avast from activating its firewall. If you have Windows Defender or another firewall enabled, disable it to allow Avast Firewall to function properly.
- Restart Avast: Sometimes, restarting the Avast application can resolve issues with the firewall. Right-click on the Avast icon in the system tray and select “Restart Avast”.
- Reinstall Avast: If the firewall still doesn’t turn on, try reinstalling Avast. Uninstall the program from the Control Panel, then download and install the latest version from the official Avast website.
Problem 2: Avast Firewall Blocking Legitimate Applications
If Avast Firewall is blocking legitimate applications or services, you may need to adjust the firewall’s rules:
- Open Avast and go to the “Firewall” settings.
- Under “Application Rules,” ensure that the application in question is listed as “Allow” or “Ask” for internet access.
- If the application is not listed, you can add it manually and define the appropriate rule.
Problem 3: Network Connectivity Issues
If you are experiencing network connectivity issues after enabling Avast Firewall, it could be due to incorrect network profile settings. Make sure that your network is set to the correct profile (Private, Public, or Work) and that no restrictive rules are preventing network access.
