I have Ubuntu 14 on my laptop and it sure would be nice of CA would come out with a compatible version! I had Windows 10 on my laptop and I'm not a fan. You have to run so much crap to just 'feel" safe. So far Ubuntu is working great for me (other than no CA for it), and as far as AV I just put a few addons to Firefox and watch what email I open so no need for AV.
I guess what I am trying to get across here is that CA needs to think about making a version for Linux!
