Avast firewall cannot start - you can do that

The Avast firewall protects your PC from unwanted interference. However, if this cannot be started, a second firewall may be active. In this practical tip we will tell you what else you can do about this error.

Avast firewall cannot start - what to do?

• Before you start the Avast firewall, you should make sure that you have not started a second firewall.
• Many AntiVir programs have a built-in firewall, which is why you should also switch them off briefly.
• After following these tips, you should restart your PC briefly for the changes to take effect.
• If you still cannot start the firewall afterwards, go to "Control Panel"> "Programs and Features" and double-click on "avast! Internet Security".
• Select the "Repair" option there and confirm with "Continue".
• Wait for the process to complete, then click "Done". It is also advisable to restart your PC here.
• After the successful restart, Avast should report "Everything is ok" and work properly.
