I've had Windows 10 Firewall disabled for ages. The last couple of days it just won't stay off - every time I reboot it's on. I guess an update to something caused this. The problem it causes is Kodi can't access the mysql instance on the PC - though I could add a rule to allow that.

I use Avira free antivirus. I thought it was that, but I rebooted today and the firewall was on, but it was marked as off inside Avira.

How do you tell the Windows Firewall to really stay turned off?
