First off, I am not asking for any comparison of any product. Only compatibility. See my AV/MalWare products license is expiring and I am considering something else, mainly because I need a license for about 10 units and I was looking for something cheaper.. Turns out the one I use works as well for W10 as for WinServer. I am not a company I have a couple Windows Server Essentials for local storage and backup, a few desktops with W10 and a few laptops with the same. So far I have browsed some of the top selling solutions (according to review pages) and it seems none use the same software version for desktop and for server. Pricing varies quite a bit as well. Suggestions?
