If the avast firewall is prevented from starting for some reason, it may not start automatically because the conflicting program is stopped. Restart the computer, and then start Avast.
Click “Start” to activate the firewall. If application rules are set, try clearing them in the “Firewall” menu to see if one of these rules is also causing firewall problems.

The firewall controls all network traffic and is capable of detecting and blocking unwanted traffic. Since many computers are connected to the internet these days, criminals have a lot of opportunities to locate victim computers. These attackers scan other computers on the internet to decide if they are vulnerable to different forms of attacks and, if your avast firewall won’t start this issue will amplify. A disabled firewall will not protect your computer from external attacks. Therefore, any malicious file may easily damage your computer, install malicious software or steal your data. Hence, a firewall is really important for your files to remain safe and protect your private data as it acts as a protective watchman in this age of internet today.
