I just updated to Windows 10 and my MapleRoyals.exe keeps getting deleted for malware. I disabled Windows Defender but it's only temporary and I'm sure it's Windows Defender deleting it.
That's the thing, in Windows 10 you can only disable it temporarily. But I googled how to uninstall it. Hopefully it'll work.
Mine keeps turning back on (after updates, I've noticed), however you can just add it as an exception to Window Defender. That's what I had to do.
