Which version of Android is your Note 10 running? If it's still on its original Ice Cream Sandwich (ver. 4.0.x) there could also be a app version issue.
Try starting up the Play Store app, tap on the three horizontal lines icon in the upper left, tap on 'My apps & games', and if there are an update listed for the Google+ app apply it and see if this will at least alleviate those pop up messages. Once updated, then try going into the Settings >> Application manager menu, find the Google+ entry and use the 'Turn off' button.
