This is about it in a nutshell. Defender working at kernel level. Who would know more about the source code and the workings of Windows more than MS?Read how W10 really works - it's a lot different to previous OS'es
MS has a site solely dedicated to safety. Microsoft Internet Safety and Security Centerand understand where MODERN threats come from when people use the Internet --Software won't save you from a lot of scams that are used increasingly commonly now. Review how YOU use the net and THEN decide what protection you need. For some people simply the best would be Never use Email !!!.
All I can say is I’ve been using Security Essentials in 7 since inception and then Defender when included in 8/8.1 along with Malwarebytes free. Also now with 10. Never a problem. Have I got infected? Sure, but caught with scans. I’ll still hold that the best solution is between our ears.The fact that someone has used XXXX for the past 20 years etc doesn't automatically make it GOOD or BAD either.
EMSISOFT is the best one I am using so far from every others I've ran.
I'm not so sure about the effectiveness of AV programs these days so sandboxing is the primary defence from threats that might come via the browser (Cyberfox at present). Nonetheless, it is recommended on the Sandboxie site to have other layers of security in place as well, so I have. No need to say what these are because people have their own preferences.
I had nothing but problems with BitDefender. I really wanted to like it based on all the positive reviews, but when I installed it on my Surface 3 it slowed it down to unbearable levels. It was so bad that even after uninstalling it I had to completely reset the Surface. Then on my main desktop websites were being blocked by BitDefender's firewall even after whitelisting them. The system, too, slowed down but not to the extent of my Surface. Uninstalling it was a pain because Windows Defender wouldn't even start up, so I had to manually dig in the registry and modify some files to get it working. Total pain in the butt.
I'm now sticking with Windows Defender and Malwarebytes Pro. I don't really go to any malicious sites anyway, so I feel safe going this route.

Don't make me laugh...Defender is about as much protection as a garden shed is against an atomic bomb.
All this nonsense about kernel level didn't stop me downloading a highjack using Edge, Defender, Mbam and Mbam anti exploit.
Infections do not only occur in the registry.
