So I uninstall the app and re-intal it. Then I discover how to replicate the alert, it appears when I open Messenger and try to open the e-mail. If I quit the process in the Activity Monitor App the Alert don't appear again no matter what I do, but if a restart the computer, in the trash appears a file named Merp Daemos and the alert appear again. But I don't see any bad effect in the computer when the alert appear so I just let it go jajajaja and now I Know what cause the alert so again thanks
