Here's what Copilot Pro has to say:
Avast Free Firewall provides advanced features like application control,
which may not be available in the Windows Firewall.
Although Windows Firewall offers decent protection, Avast’s Firewall is superior,
stopping a higher number of threats from accessing your device.
Bottom Line: For an average user, both firewalls should provide adequate security,
but Avast’s Firewall offers a stronger level of protection.
