I was installing chrome on a work computer, and windows defender was automatically flagging the chrome installer (official, directly from google) as malware and deleting it automatically as soon as it was downloaded. It wasn’t blacklisted for very long, I was able to download it without issues the next day, but I always have wondered if that was something they were testing out on purpose or not.
I’ve been using Linux as an out. “Oh you’re having a windows problem? I got rid of windows 10 years ago, so I can’t really help you with that”.
