Files required for the game

Additionally
If your antivirus "swears" at the MuOnline game files, considers some of them a virus or suspicious, and deletes them, then just add the folder with the game to the antivirus exceptions. Game files are not dangerous and do not pose a threat to your computer. However, some antivirus programs and firewalls may mistake the internal structure of MUonline files (an anti-cheat system) for malware.
