Mapleroyals frequently deleted by system

Hi, my mapleroyals has been deleted automatically for several times, which always happened when I turned it into full screen mode

I had to re-install the client again and again.

I've already add it into the Whitelist of my Firewall, but it still happened just now.

Could anyone help me? thank you!!!!

 

You'll have to research into the kind of antivirus you're using, and how to add exclusions.
