Winblows does that for all unsigned programs. You can ignore that warning. Signing programs costs money, so some programmers just don't bother.Speaking of ERA TohoK, I've tried downloading it, but when I try to open it through the Enumera-anchor Application or whatever, I get a Windows Defender popup warning me it might be malicious and comes from an unknown publisher. I have had this happen before with other indie games and clicked to run it anyway, but what doesn't happen is that when I clicked it my laptop just deleted it. Just that one specific application and nothing else. I've tried through various sources to get a new link and have kept deleting and redownloading over and over again but my laptop won't let me play.
