Replied to your PM but will post here as well, it's Macroquest2.exe itself, detected by Windows Defender, I should note I'm using the Test server compile too.
I don't think anyone is stupid enough to believe there's a trojan injected into it, anyone who's ever used cracks for software/games knows these things are often detected as trojans.
However, I did have to reinstall MQ since it deleted the exe, I also had to reboot my PC which anyone with a PCI-E SSD can verify takes a good 8 to 10 seconds, therefore I think I am entitled to a 2-3 year free subscription settlement for the pain and anguish this has caused.
