    Chalk another one up for "Antiviruses causing more problems than solving them".

    They 'worked' when they initially just scanned files for known malicious signatures. Now they're the equivalent of a sledgehammer to a wall with all of the extra bells & whistles strapped to them.

    Application whitelisting is the remaining way forward if you actually care about runtime security. That & locking every access point down to the bare minimum.

      Antivirus is not a bad thing. Imagine running a company where there are 100 employees that click every link and open every attachment. Definitely safer with an antivirus.

        I imagined it with employees on Linux and it wasn't clear to me it's definitely safer with an antivirus software. You are just stating things without explaining yourself...

          Maybe you’re imagining no local privilege escalation vulnerabilities. Those are low severity in general, but if you can get a user to run something it’s all over.

          How much do I need to go on? A foothold on a local computer allows the attacker to spread horizontally across your network.

          It’s just a matter of time before you’re fighting real-time AI-driven attacks (most sites aren’t yet). Good luck even with your antivirus. Which I agree is going to be one of the footholds that is used against you.
