When trying to open firewall with advance security: "There was an error opening the windows firewall with advanced security snap-in The windows firewall with advanced security snap-in failed to load. Restart the windows firewall service on the computer that you are managing. Error code 0x6d9" Cant find windows firewall in my services list, not sure if its called something funny. Saw another thread they asked what antivirus they had, I use AVG 2012 When opening windows firewall and trying to change it to recommended settings it gives: "windows firewall cannot change some of your settings error code 0x80070424

Hi, From your description, I understand that Windows Firewall service is missing. This issue can be caused by the virus or the conflicts between third-party software and Windows7. As a result, please scan for virus first and run System File Checker. Then, test the issue in Clean Bootenvironment.
