Samsung S6 keep showing Device Security "1 threat detected"
There is a workaround provided at XDA forums which involves disabling the security log agent. I believe it is also the cause for the "Threat detected" alert notification.


Install free Package Disabler from Google Play Store.
Launch this app, search and disable "Security Log Agent".


Doesn't need root :)

This should fix  this annoying notification again.
