Add the game to your exceptions list on your anti-virus program. I can assure you the Emps client does not have any viruses.

Always when i try install my antivirus blocked it, BECAUSE emps-world client try install "trojan.GenericKD" Virus.

Can you tell me which anti virus scanner you are using? There are false positives, meaning that an anti virus program detects an unknown file (Emps-World) as a virus, although it isn't.

EDIT: I've seen you made a helpdesk ticket. Locking this topic, we'll help you out via the helpdesk.
