Despite uninstalling this app from my tablet, and then trying to reinstall with new activation code it comes up with install and won't reinstall. My old subscription is expiring today. What a crapp s system. I don't have twitter or face book and I don't want that sort of rubbish on my devices. So Norton get real and provide a sensible and useful service. I have been using Norton security for over 25 years and have had no problems on a pc, but with Android and having to log in with Google on my phone to install what I have already purchased is very annoying.
