Files

Some antivirus programs may flag MU Online game files as suspicious — this is a false positive.

The Emberion client contains no malicious software of any kind. Certain antivirus tools and firewalls may misidentify MU Online's built-in anti-cheat system as a threat due to how it interacts with system processes. This is a known and common occurrence with MU Online clients worldwide.

If your antivirus removes or quarantines game files, simply add the Emberion game folder to your antivirus exclusions and restore any quarantined files. The client you downloaded from our website is safe, unmodified, and verified by our team.
