I have recently installed Norton Security Deluxe on two PCs. I am now trying to install on to my Sony Xperia mobile and have sent myself the required email, clicked on "Install" and Google Play Store comes up and states that Norton Mobile is already installed. I had previously uninstalled Norton Mobile and it no longer appears in my APPS list. Security Deluxe will not install.
My account is showing just two seats being used.
How do I remove whatever is causing the Phone to appear as if Norton Mobile is still present?
