Symantec has direct links to malicious websites?

Salutations,

I was just browsing through the NIS 2010 vulnerability protection.

Clicked on additional information on a vulnerability.

http://www.symantec.com/business/security_response/attacksignatures/detail.jsp?asid=22678

I just browsed through it and scrolled down till “Additional References”.

I clicked on “NOHACK Advisory”.

It brought me to a website and my Norton Safeweb reported that there are threats on the website.

So, do i need to do some scanning of my system now? Or did i make a mistake and it isn’t a malicious website.

Sincerely,
Pikachu
