Norton 360 - Safe Web query

Recently, I had to renew the Settings for my Zyxel P2002L 'Phone Adapter.  This required applying a new "Internet Location" for the Adapter.

 

When I now enter the new Internet Location, to logon to the Settings, the Safe Web displays a "Cautionary computer threat" and the Full Report indicates a "Malicious site : Malicious Domain request 2, quoting the new Internet Location.

 

A previous Setting never identified this problem. What have I done wrong?  Is there something I should correct?

 

Regards.....
