There's a better way to disable any package by using the adb pm uninstall
command.
Note that this will not actually uninstall the app, but will only hide it from the system. Best of all it works on non-rooted devices too!!
Enter this from your adb folder:
adb shell pm uninstall -k --user 0 com.wssyncmldm
If you really want to get rid of a lot of Security+OTA nagging, then run the following list of commands. Optionally you can save it in a batch file to make it easier to run. Note: Some packages will fail to uninstall which is fine, since this is a generic uninstall list for various Samsung models.
