You can very easily disable the app causing it to be no longer present in it's unextracted form, meaning it's effectively uninstalled.

Last I checked Google+ was the one spyware that you couldn't get rid of even when you rooted the phone. I.e. once you disable G+ all sorts of unrelated apps will hang/force close.

Admittedly it's been a long time since I tried, perhaps they fixed it since then.
