A disabled firewall often means that your computer is not 100% protected from external attacks and it’s quite important to take care of this problem quickly. There are quite a few methods to get rid of this problem so make sure you try them out.

Solution 1: Scan Your Computer and Run the Repair Tool

When a certain security setting fails to turn on, it’s logical to assume that a malicious tool is preventing this for the purpose of being able to connect to the Internet and harm your computer. You will need to scan your computer Avast and at least another security scanner in case Avast scanners are being affected as well.

Since you are not sure if Avast is currently blocked from searching for the correct files, you will also need to employ another free scanner. Malwarebytes is a highly successful tool which you can download as a free trial and which can help you deal with these kinds of threats. Follow the instructions below in order to download and use it.

Finally, it’s time to repair your Avast installation by following the short set of steps below. Users have stated that repairing the installation didn’t work if users haven’t scanned their computers beforehand so it’s important to first scan your computer entirely for viruses.

Solution 2: Perform a Clean Reinstall of Avast

If the program itself has become buggy due to programs conflicting and similar, you may haveto perform a clean reinstall which will setup the Avast tool from the very start. The process is quite easy to follow and this is a solution you shouldn’t skip, especially if you switched from another antivirus tool before using Avast.

Solution 3: Turn off Windows Firewall

It’s a known fact that two different antivirus or firewall tools usually fail to coexist together and that is why it’s important to disable the Windows Firewall as it does nothing more than prevent Avast from turning on and it most likely causes these issues to your computer. Follow the steps below in order to disable Windows Firewall.
