Safe Website Incorrectly Blocked

I submitted a request to the Symantec Security Response Anti-fraud team to fix the incorrect blocking of the Brookdale Community College website (http:// www. brookdalecc .edu/).  Their response was: "Our analysts have been unable to reproduce the suspicious phish site verdict on the provided URL."  However, the problem persists, with three different browsers.

Firefox gives an error page saying: "Dangerous Website Blocked".

Firefox, Chrome, and Internet Explorer all give a note with a red x in the Norton Toolbar saying: “this page is unsafe".

How can this be fixed?
