How do I whitelist a site (Nighthawk RAX50)

First, why isn't my model listed when I try to fill in the model when posting a message?

Second, how do I whitelist a site?  I went to a forum website and when I tried to logon, I got:

Stop!

NETGEAR Armor has blocked this site for your protection! It might contain malware, phishing, fraud attempt or other forms of criminal content that can infect your computer, get sensitive information such as passwords and credit card details or compromise other devices.

We suggest that you go back to safety.

How do I fix this?  There isn't even a way to bypass the warning.

Thank you.
