    Prevention and detection

    Most of the time, detection also means prevention, but with a whitelisting antivirus, prevention often means that the threat isn’t detected, it was just prevented from running.

    A whitelisting application has a list of what it knows it bad AND what it knows in advance to be good.

    Anything it can’t identify on the spot is treated as unknown and not allowed to run, not deleted, not quarantined, just blocked from running until the user can upload it to things like virustotal and other services like it to figure out if its safe.

    upload it to virustotal, if it wasn’t already known, do a re-scan a few hours later to see if it’s malicious, if it was already known, do a re-scan to see if anything has figured out if its malicious.

    which is why I think it’s borderline criminal that most antivirus programs don’t work that way.

    At least microsoft is honest enough to admit their software needs protection, unlike apple and unlike most of the people who have made distros of linux. (edit: microsoft is still dishonest about what kind of protection it needs though)

    Even though apple lost a class action lawsuit for false advertising over the claim “mac can’t get viruses” they still heavily imply that it doesn’t need an antivirus.

    any OS can get infected, it’s just a matter of writing the code and finding a way to deliver it to the system…Now you might be thinking “I’m very careful about what I click on” that’s a good practice to have, but most malware gets delivered through means that don’t require the user to click on anything.

    You need an antivirus on every computer you have, linux, android, mac, windows, iOS, all of them. There’s loads of videos on youtube showing off how well or not so well different antivirus programs work for windows and android.
