For the past years it seems like even Windows (given the large attack surface) viruses/trojans have become much less common than in the past. I think the first line of defense in web browsers and various techs like SmartScreen etc. has helped especially with fishy porn ad ridden websites wanting to download FixWindows.exe, but also that we've moved to often use cloud oriented tools. Nowadays we visit websites to get things done way more often than in the 80's / 90's when we ran executables from some friend's diskette or hard drive. And as long as we visit websites it's way too much effort to exploit weaknesses in their sandboxes that this is then almost entirely about targetted attacks. Another example of how obnoxious it is becoming to merely _get_ to someone's computer to infect it now that users rely less on executables, is that the Fake Indian Microsoft Support Technician has become a thing. Actual humans calling other humans and hoping for the best by social engineering. This is so far fetched and works so rarely that the desperation is real. E-mail has been another traditional way of getting to someone but that's nowadays mostly Outlook.com or Gmail.com, which have their own very efficient AV systems in place. I guess my point with this is that even Microsoft's so-so antivirus tool (given that it's less intrusive) should indeed be enough. Hell I think a user with common sense will be fine with no AV whatsoever for longer than one may think.
