Hi I need to be very careful in answering this - different people have different views on what you need and also people use different operating systems that have differing levels of risk. Personally for your Android device, if you only install apps from the Google Play store and use the recommended app scanning tools and settings from Google as well as practice safe browsing in Firefox for Android - you should be okay. I do not know what other services the Norton app you have installed provides, and some of them may be of use, but personally, most of what may be there is probably already in Android. For your computer - I do not know whether you are using Windows or MacOS. Assuming it is Windows, a well respect Mozillian advised me that all you really need is Windows Defender and possibly Malwarebytes. That said, if you have paid for a Norton product, it may be better value to use that for the period of the subscription before looking to change instead of paying more money.
