Why am I getting a Norton pop-up message?

Why am I getting a Norton pop-up message that my network is not password protected and I need to turn on Norton VPN while Norton Smart Scan says that it " is password protected and has strong encryption"?

[Edit: Calrified the subject]

Can you post a screenshot of this message?
