After installing the latest version of McAfee Innovations, I started the Notification Listerner in the new Notification Blocker tool.
But now I am unable to stop the actual service running.
On going into Apps, Running Apps, McAfee Innovations, there is a Settings button that when clicked, does absolutely nothing.
I am running this on a Nexus 5, ver 4.4.2 of Android.
Please go to settings > security > and then search for notification access
then uncheck MMI
