so, I've had my current computer for about... four years? very happy with it, haven't had any trouble really.
But something that has been nagging at the back of my head is that 3rd party product Microsoft Security Essentials has been discontinued, and replaced with the built-in 1st party Windows Defender. MSE came highly recommended by PZC alumni back in the day and did a good job. However, despite having had no problems, I'm wary of something that "came with" the current PC. I feel like I'm far better off using something else.
What is everyone's take? What's the popular AV out there?
I'm not just asking for myself, but for my girlfriend too, who is running Windows 8. I myself use Windows 10.
