NEED RE-EVALUATION AND REMOVAL OF NORTONS INACCURATE MALICIOUS SITE RATING

As a restaurant owner with a web-site  presenting the public with our offerings, I can't afford to have people using Norton products tell me that my site is listed by Norton as a "malicious site and that they should exit immediately" A complete security audit of my account was made and did not find any security issues. What Norton is using as to their records was deleted from my account March 26, 2010 over two years ago. I want the malicious "news.php" file, re-evaluated and subsequently delisted.  My account is secure and clean. This information is coming from Superb Internet Corp, my hosting company.
