As of yesterday march 31st 2015 Emsisoft's Online Armor is no more. It is officially replaced with Emsisoft Internet Security.
As of today, we have stopped selling Emsisoft Online Armor. New license activations will only be possible until the end of May 2015. The official end of technical support will be March 31, 2016. Though, we will still provide updates for critical issues that may be discovered until then. At the moment we can say with certainty that we will not add Windows 10 compatibility, since that requires several major changes to the codebase.
