Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

      If you insist on running untrusted executables and refuse to fix that problem, then you're screwed and antivirus doesn't change that. It's plausible AV will increase the amount of time your system is usable between reinstalls, but that is not security.

      Yep, but the context here is "how to not get hacked" guides. If you're not running random untrusted executables, then antivirus is a liability. If you are running untrusted exes, then you're gonna get hacked.

      So "don't use antivirus" does have a place in these guides, right above the explanation of how trust works with executables.

      I don't think it's as complicated as people claim. People understand how to evaluate if they would let you use their laptop in person if you asked. They don't understand that running an exe you wrote is exactly equivalent. IMO, when you explain it like this people get it.

      It's even worse than letting you use their laptop because the executable might have malicious content you don't know is there.

          More like letting you use their laptop in a body-snatcher-infested dystopia where they can't know if you are really you.

          No. ppl trivially tricked into clicking thru warning dialogues to view a "document" named this_is_obviously_a_virus.exe attached to obvious scam emails is catastrophically high. Not just "old" ppl; also kids growing up on mobile. They barely know folders, let alone file .exts

          Until we have general purpose operating systems that can survive users deliberately going out of their way to click every single thing they're told click, I'm afraid AV will be of more benefit than harm to most people.

          You want people to be able to run untrusted executables safely and think antivirus allows that. It doesn't. Believe it or not, you're not the first person to notice users will "click stuff", I don't need this pointed out 😉

          Apologies for re-stating the obvious. However, it's not that I want them to run untrusted executables safely, nor do I think AV allows that. It's just that no AV is demonstrably worse than having AV for these folks.
