Easy Anti-Cheat is a monitor program that detects cheat, hack, and other similar abnormal programs that may hamper the game system.

The pop-up window may appear if there are programs that interfere with PC communication or if there are anti-virus softwares such as Alyac or Avast that collides with Return Alive. Please check if there are any programs that have been installed before or after the pop-up window started to appear and try to only run Return Alive with no programs running in the background.

If this issue persists, please contact support with screenshots included.
