This is part the AV/FW vendors fault, part Microsoft's fault. Yes, on Windows the security products are too often as nasty as the malware they claim to protect you from but Microsoft has failed to design a sane security experience that works with legit 3rd party vendors. Currently on Windows 10, it's surprisingly difficult for "normal" users to know if av/fw are available by default and how they work. How the built-in security works with 3rd party solutions is more confusing, even for power users.
