I hope I'm getting downvoted for my sarky tone. There have been stories that other vendors are even worse but it doesn't matter, they should've updated Defender 12 years ago concurrently with IE as they were developing the tech for Vista, because.. Defender has high false negative detection ratio and so is a plan B, hail marry kind of technology - you should do everything so that you don't rely on it working as it works only passably well for a percentage of stale threats. That's why if it and similar software is enabled it should affect your security only additively and should never contribute to attack surface. Instead in an effort to check if a file contains any of months old malware you get pwned by a bug in decompression function for a file that that you didn't even open that just passed your system and so you'd survive the attack if it weren't for the system that tries to help you survive attacks stupidly.
