Website Blocked

Good Morning

I am trying to use a website that Norton has blocked as being as unsafe. I know if I continue I do so at my own risk. I am allowed to go to the website which I am a registered user of. When I try to log in I am continually being blocked and cannot use the website after that point.

I understand the risks and should be allowed to use the website if I so wish. How can I get Norton to let me use this one particular website?
