Comment on Alternative to ClamAV?

  I have been using linux for almost 2 decades, never seen a virus. And I never heard of a colleague or friend who got one on Linux. That’s why no one has ever installed an antivirus, because, till now, the risk has been practically zero.

  On windows, on the other hand, I saw so many viruses on friends and relatives computers…

  People install antiviruses depending on the experience.

  To be fair, we all know on Linux viruses exist, but is objectively pretty difficult to get one. It is not worth installing an antivirus if one doesn’t actively install garbage from untrusted sources

    It’s not any more difficult to get a virus on Linux than Windows. It comes down to experience as you said. I’ve been using Windows for my entire life and haven’t gotten a virus since I was 8. But all it takes is one mistake on both Windows and Linux, you accidentally leave a docker endpoint or ssh server exposed and insufficiently protected on Linux and you’re going to get a virus the same as if you accidentally opened a .pdf.exe on Windows.

      Not at all. You leave a ssh port open, you don’t get a virus. Try it. Set up a raspberry pi, install ssh and leave the port open in your firewall. It is much less risky than exposing rdp (the most comparable windows protocol) on windows for instance.

      It is a security risk, but absolutely not comparable of installing pdf.exe.

      As said, try it now and tell me how it goes.

        Glad you asked, I run a ssh honeypot and get multiple connections adding ssh keys, trying to run lockr, downloading shit every day.

  What happens in the Windows world: Microsoft is not capable of creating and distributing a patch timely. Or they wait for “patch day”, the made up nonsense reason to delay patches for nothing. Also since Windows has no sensible means of keeping software up to date, the user itself has to constantly update every single thing, with varying diligence. Hence Antivirus: there is so much time between a virus becoming known and actual patches landing on windows, that antivirus vendors can easily implement and distribute code that recognizes that virus in the meantime.

  What happens in the linux world: a patch is delivered often in a matter of hours, usually even before news outlets get to report about the vulnerability.

    Zero days aren’t the only way you get viruses. Misconfiguration and social engineering are both vectors that are OS agnostic.

      But do antivirus really help with that? Is it going to check for open ports and see if the service listening has a strong password?

      You can’t program against social engineering or missconfiguration, and because those are the only real vulnerabilities in Linux there’s no need for antivirus.

        No but it can’t do that on Windows either, all it can do is detect an infection and attempt to remove it. Same process would be applicable on Linux.
