The issue previously reported by Morac seems to be back again: http://community.norton.com/t5/Norton-Internet-Security-Norton/Issue-with-communicating-with-the-One-Click-Support-server/m-p/146916
If so, would you please identify and correct the bad or misconfigured network port at Norton/Symantec as soon an possible.
I'm using Norton Internet Security 2010 and the problem showed up this morning (Swedish time).
