On Windows 10 I'm trying to resolve an issue with the Origin installer, one of the suggestions for which is to temporarily disable the firewall when running. However, I go into the firewall settings in the McAfee Security Centre application, click Turn Off, select to turn on in 15 minutes from the drop-down, click Turn Off again - and absolutely nothing happens. On that page it still says Firewall:On; on the PC Security tab it still says the firewall is on. I've googled and can find no solution. How do I turn the thing off??? #firewall
