It's a program called Ellinia.exe that's a client for a Maplestory private server. MS private servs are notorious for tripping antivirus alarms. Been playing them for years and they haven't installed malware on me. Previous computer (Windows 8.1 home, I think) had the program as well, and the antivirus I had on that computer didn't mark it as malicious.
