When you connect to a VPN, all your traffic is encrypted. This error is usually quite annoying because it appears on a daily basis and it also appears in random intervals which leave the user confused about its origin. The error is not exclusive to Windows 10 and it can also appear on older versions of Windows since they all contain the Windows Firewall.

When new programs are installed, the Windows Firewall does not know how to react to them and it displays the message below. The message is usually related to certain online multiplayer video games, Internet browsers, etc. The problem shouldn’t be difficult to solve if you follow the solutions below carefully!

Solution 1: Add a Program to Windows Firewall Exceptions

In order for each app to be allowed access to Internet, it needs to be allowed through your firewall. You should always pay attention to the type of apps you are allowing through your firewall as malicious apps will then have access to the Internet and your computer as well. Follow the instructions below in order to allow an app or a feature through Windows Firewall:

Solution 2: Uninstall Third-Party Network Drivers or Programs

Sometimes this particular error appears when users download and use third-party VPN tools such as Tunnelbear, Hotspot Shield or some other. These programs sometimes install a device in the Device Manager which causes these issues with the Windows Firewall. Removing the program and the driver is not a difficult process so make sure you follow the instructions below.

After you have uninstalled the program, its driver may have remained on your computer and issues may still appear if you don’t uninstall it by using the Device Manager. Follow the instructions below.

Solution 3: Scan Your Computer For Malware

This issue can also occur if the user’s computer is infected by malicious applications because they reset the changes you make to Windows Firewall settings even after you allow your apps through multiple times. These malicious applications need to be dealt with as soon as possible because the annoying Windows Firewall pop-up is probably just the tip of the iceberg when it comes to potential damage to your computer. Follow the instructions below in order to scan your computer.
