I think it is always there, I never use the My Norton much, I stick to the Classic start page
One thing to look out for as well, this may help
@Hazel123 and
@CornishRattler if a file or download is quarantined as WS.reputation.1 it probably is not a problem as it means the file has had so few downloads it has not built up a good reputation yet. What I do is remove it from quarantine and drop it into VirusTotal if nothing flags it I assume it is ok. Another badly worded thing from Norton, I am sure it is to scare us.
