This has happened to me before but not for a while. I was uninstalling some old rubbish from my pc today and a few minutes later a warning popped up from windows saying security issue no anti virus/firewall. Norton in the taskbar was showing a green tick indicating all was ok. I went onto the security section on windows 10 and it said no firewall was on and windows defender was on for anti virus. I clicked on firewall and yes i trust norton but it still didn't change. Looking on norton security everything was turned on. I did a full shutdown and after 10 minutes or so windows said norton was now running I am confused as to why this would happen and am wary now that i am not properly protected. Is this common?
