Remove Inactive Norton Family software

I installed the free version of Norton family on my daughter's Android phone about 2 years ago.  Now I would like to remove it... when I attempt to uninstall I get prompted for a username and password.

The problem is that I believe Symantec has purged my account due to inactivity.  I tried to recover my password and I get the following message from Symantec:

"The email address  bbking67@xxx.xxx is not associated with any Norton account."

So how can I remove the app?  I don't think that wiping all data on the phone is a viable option, so don't even bother suggesting it.  :-)

I feel that the application is using system resources, and her phone is already slow enough.
