Internet Security Issue.

So this is my second year using the norton 360 annual program, and so far its been good. i've had afew problems, but most were easily fixed.However, Today i got a E-mail from a 100% trusted site called runescape(www.runescape.com) The main site has been confirmed safe. However, i got an email requiring that i log on to confirm this is my account, because i changed the emails. I AM 100% CERTAIN THIS IS A LEGITEMATE. However, when i click on the link i get a page saying:

 

Fraudulent Web Page Blocked

 

You attempted to access:

 


This web page is a known fraudulent web page. It is recommended that you do NOT visit this page.

For your protection, this web page has been blocked. Visit Symantec to learn more about phishing and internet security.

 

There is a button on the bottom of the page that allows me to continue anyway, But when i click it, it redirects me to the page above.Any suggestions?

 

Note: Post if you need more details/Screenshots.
