Could be just a momentary glitch with something being slow to react. I searched the forums for "McAfee (note 1 " f ") 32-bit helper stopped working" and got a few hits. It seems where it occurs frequently the only solution is to uninstall the software via Control Panel, then run the MCPR cleanup, reboot and reinstall from the online account.
But if you are seeing normal behaviour since, I wouldn't bother with that unless things deteriorate.
This the first time it's happened. I will continue to monitor.
I would like to wish you and everyone else a happy and healthy Merry Christmas and a prosperous New Year.
Thank you Jerry and all the best to you and yours. ;-)
