May i know why when we install the setup at the end my antivirus delete automatically *infostealer* which is mapleroyale.exe isnt that a keylogger and why would that be in the setup of this game?
It's a false positive. Anti-viruses aren't too friendly with encrypted applications I think? Best thing would be to add the .exe to the list of exceptions in your anti-virus software.
I have played this server for exactly half a year (Nov 10 - May 10) and have never had problems. I can guarantee it's a false positive, most servers have this problem. Just whitelist in your antivirus software settings.
