A firewall is software or hardware that helps prevent hackers and some types of malware from getting to your PC through a network or the Internet. It does this by checking the info that’s coming from the Internet or a network and then either blocking it
or allowing it to pass through to your PC.
A firewall isn't the same thing as an antivirus or antimalware app. Firewalls help protect against worms and hackers, antivirus apps help protect against viruses, and antimalware apps help protect against malware. You need all three. You can use Windows
Defender, the antivirus and antimalware software that's included with Windows, or you can use another antivirus and antimalware app.
You only need one firewall app on your PC (in addition to the firewall that's probably built into your network router).
Having more than one firewall app on your PC can cause conflicts and problems.
Windows Firewall comes with Windows and is turned on by default.
If you really think that you're safe and comfortable with the other firewall, then you can turn off the built in Firewall.
Turning Windows Firewall on or off:
You shouldn’t turn off Windows Firewall unless you have another firewall turned on. Turning off Windows Firewall might make your PC (and your network, if you have one) more vulnerable to damage from worms or hackers. To turn Windows Firewall on or off:
In Search, type firewall, then select
Select Turn Windows Firewall on or off. You might be asked for an admin password or to confirm your choice.
Note: If your PC is connected to a network, network policy settings might prevent you from completing these steps. For more info, contact your administrator.
