Windows Defender / Antivirus Notice (False Positive)

Because our Launcher and client are custom-modified to support native HD Widescreen and connect to our custom emulator without legacy protection, Windows Defender may flag it as an unrecognized file. The files are 100% clean and virus-free. If the blue SmartScreen prompt appears, simply click "More info" > "Run anyway".
