The Trust Rating
A file has several trust levels.
Unproven: Norton has analyzed this file and found it to be safe.
Good: This file is found frequently in the Norton Community and has not been reported as infected.
User Trusted: You have marked this file as “Trusted”. You can change this rating by clicking “Trust Now”
Not Trusted: Not enough is known about this file to be certain that it is safe. You can change this rating by clicking “Trust Now”.
What qualifies as "frequently"? I ask this because I submitted (#13747748) a known fake AV that has been seen by less than 10 community members but has been classified as having 'Good' trustworthyness. (The file downloads Adware.Gen and a Trojan)
