Norton Premium to Android tablet

I have in my PC Norton security Premium. Now I would like to install Norton to my Android tablet. Even if I sign in to Symantec it guides me to Google App Store. There I am asked to sign in to Google with user name and password. I'm not registered to Google. Furthermore if you go to Google App Store you can see that the Norton Security & Antivirus product is free. Question: Can I download from somewhere Norton Premium to my tablet or is the only way to register to Google and download a freebie. 

One reason to buy Norton was to be able to install the same program to my mobile devices.

The only way to get the Norton Mobile Security is from the Google Play Store. This is also true of most apps for Android devices.
