      Honestly, obviously an antivirus industry advocate thinks people should give more money to the antivirus industry. A better story would be hearing you rationalize that, and hear why giving money makes antivirus better. 😛

      Who asks that? They already have AV, so is the real question "should I disable mpsvc?" or "should I pay/have newtab page hijacked instead?". The answer to first is "complicated, but doesn't matter too much, ms actually know what they're doing", answer to latter is "lol no".

      "They already have AV." What if they have a Mac? What if they run an older version of Windows? What about mobile? Respectfully, assuming everyone has a Win 10 box (if that's what you're suggesting) is just wrong.

      If they have a Mac... they really shouldn’t install most “AV” products out there... basic education on Mac and Gatekeeper and default system policies should be good enough.

      Not a Mac expert, but people manage to install malware on their Macs all the time. That's what matters: a) is it relatively easy to install malware and b) are you someone who can't really make a distinction between malware and goodware. If 'yes' to both, you're better off with AV

      Yes, and so is "install antivirus". However, "Get a ChromeOS/Win 10 S/iOS device" is very good advice.

      No, antivirus doesn't work and telling people it does is misleading. If I told you I had a vaccine for salmonella so you don't have to worry if your food is cooked properly anymore, you would be pretty angry when you got hospitalized when you stopped checking.

          That's not what I'm talking about, although as you ask - we know that Antivirus exploits are actively traded, but we have no insight into their use (how could we?). I'm saying that antivirus cannot stop viruses.

          Also worth mentioning that times have changed, many attacks are more organized and targeted. Many of which stay one step ahead of the virus vendors. When last did we hear the term "virus" actually be used in an attack?
