Im running MWB v 184.108.40.2067, component package version 1.0.342, update pkg version 1.0.4072.
Same thing. Real-time protection disabled and grayed out. To note this has been gong on for some time. Think this first occurred for me summer of 2017, and never went away. Did all the clean utility, reinstall, etc, reinstall. I have have had at least two upgrades since it first began. This is not new, not fixed, pervasive. Been paying for real time protection for half a year that is disabled. Its not a current version issue.
