Lol.. yeah like that's affordable for a home user!
States on Endpoint Protection:
Microsoft Windows Server 2012 and Server 2012 R2 (any edition with latest Service Pack, x64bit, incl. Small Business Server/Essentials, except Server Core)
So that should do for $39
..Although now im not sure, as some of the icons are greyed out... Ill just try it out and see!
Not very clear their website really...
