Norton's Security Lock can be uninstalled even without logging in. I assumed (incorrectly) that once the Security Lock was activated after signing in, then once I signed out of Norton Mobile, the Security Lock could only be turned off after my signing in again. This would make sense in that if the phone was lost or stolen, the person in possession could not uninstall Norton and I would have time to acquire a phone to send a text locking my "lost" phone and activating a scream, etc.
Does anyone know how to securely lock the Security Lock or the Norton app?
