Sophos has 10 devices are free for personal use and you get to use their cloud central management. https://www.sophos.com/en-us/lp/sophos-home.aspx

I talked with their rep at a business conference and he said that it’s the same business-grade security foryour home Macs and PCs. They use 2 VB100-certified AV engines in their products. I’ve tried their home version out on 2 different devices now and it seems to run great, plus I used the central “cloud” management console to put in an exception for one of the devices and the device’s policy updated almost instantly.
