Norton Client Flags Clean Site

Norton,

 

Site: http://tinyurl.com/chvzy95

 

I'm getting reports from several of my users that my site is being flagged by their local Norton antivirus installation as an attack site.  No other anti-virus software is reporting any issues.

 

The Norton message (attached) is stating that "Network traffic from ads.northamericatalk.com matches the signature of a known attack.  the attack was resulted from \DEVICE\HARDDISKVOLUME2\PROGRAM FILES (X86)\INTERNET EXPLORER\IEXPLORE.EXE."

 

ads.northamericatalk.com is an OpenX ad server that we manage and maintain.  It is fully patched and running the latest version of OpenX.

 

My site is registered with Norton Safe Web and comes back clean:

Why is the Norton client blocking the site?  Any ideas?

 

Thanks for your time.

 

Regards,

Stephen
