help Windows Defender Firewall FAQ

Is Windows Defender Firewall the same thing as an antivirus program?

No, the Windows Defender Firewall is strictly a network filtering system that monitors incoming and outgoing traffic to block unauthorized connections. It does not scan for or remove computer viruses, which is the job of a separate antivirus program.

Can I block a specific application from accessing the internet using Windows Defender Firewall?

Yes, you can create custom outbound rules within the advanced security settings of the firewall. This allows you to prevent specific software from communicating with external servers while keeping your general internet connection active.

Should I turn off Windows Defender Firewall if I am installing a third-party security suite?

If you install a comprehensive third-party security suite that includes its own firewall, the software will usually disable Windows Defender Firewall automatically. Running two software firewalls simultaneously can cause network conflicts.

How do I allow a new multiplayer game through the Windows Defender Firewall?

You will need to access the "Allowed apps" menu within the Windows Defender Firewall control panel settings. From there, you can check the box next to the game's executable file to permit both public and private network traffic.
