Windows 8.1 error message re: Windows Firewall


Hi, just got a new computer (HP Envy laptop) with Windows 8.1.  Uninstalled Macafee and installed Norton 360 as I have a subscription.  A few days later, got a "Open Actions Center" notification (red flag right corner of computer) telling me both Norton firewall and Windows defender are turned off.  Checked Norton 360: Smart Firewall and antispyware is switched on, but I run every possible update and scan, and everything is fine.  In Control Panel found Windows Defender under Security, and it is marked off.  When I try to change it I get this error message: "these settings are being managed by vender Norton 360."

What the heck is going on?   In Win 7 I never saw any language about Norton controlling Windows Firewall.  After an explanation could someone offer a fix?  It is really unnerving to have an error message telling you your brand new computer has no firewalls. Thanks!
