And it's not just breaking the actual code, it's breaking the standard communications and formats that all major browsers use.
I've personally seen HSTS, HPKP, HTTP2, TLS1.3 and more all get royally fucked by various AV programs. And that's just from doing tech support for my family.
I understand that if an AV wants to protect certain aspects they need to get access to it, but using these hacks, workarounds, and more to do it is not only unprofessional but both a security and usability nightmare.
It's also why the only AV i'll ever recommend will be Windows Defender. People like to complain that it doesn't "catch as much as the others", but at least it's not actively breaking shit.
