I read this post on fsxNet and thought it's worth sharing. https://pastebin.com/PeC6VKpj A hobbyist developer published an ANSI art program, and one person said Defender flagged it as a virus called "Trojan:Win32/Sabsik.FL.A!ml" Thing is, THIS ISN'T A VIRUS. It's a moniker for code determined by heuristics algorithm to be high-risk. The "!ml" suffix means "machine learning". This approach is good, but the naming spooks people for no good reason. What's the developer to say except "Trust me!" ???
