When I click on windows security alerts its says firewall is off. It says windows detects that your computer is not currently protected by a firewall. Then it says click recommendations. Then it says turn on all windows firewall for all network connections. I click enable now and it says we're sorry the security system could not turn on windows firewall. Then it says try turning on the firewall yourself by going to control panel and clicking the firewall. Then it says do you want to start windows firewall. Then i click yes and it says it can't start it. What do i need to do so i can turn on my firewall? I don't know what to do. Thanks
