jwg35815, we want your phone and its layout to your liking. If the steps recommended by bearone21 did not lend a hand in removing it, then let’s look further.
First let’s see if you can locate McAfee in the Play Store. Does it come up when going to Play Store > Menu (3 lines in the upper left) > My apps and games > Installed?
If so, then tap it. If Uninstall is available, then select it to remove the program.
