Why does my AntiVirus turn off my Windows Firewall?

Episode 1056 (2:32:03)

Dave from Roseberg, OR

Dave recently upgraded to Windows 8.1 on his laptop and now he's having firewall issues. Leo says that third party security software is often incompatible with Windows firewalls, and will disable Windows firewall. If you like the job your AVS does, then let it disable it. Leo happens to think that Windows Defender and Windows Firewall does a great job and you don't really need to third party option.
