I am a bit confused whether I am covered with Firewall protection or not, we have had this Laptop just over a month and has Windows Defender built in and had Mcafee trial for a month, but now that is finished, we keep getting a pop up for us to sign up. But I read that Windows Defender has it built in, so looking at these images I have downloaded, would you say I am covered or not? Not understanding the difference between them.
