Norton Internet Security 2006

NIS appears to blocking www.streamaudio.com.  I have been told to go to Antispam on the left side of the screen.  These directions are also on the Norton site.  http://service1.symantec.com/SUPPORT/nip.nsf/0/6f94cfaf79c14b828825707a0070dc89?OpenDocument&seg=hm&lg=en&ct=us  Although I have NIS 2006 version 10.3.0.12, I have no Antispam on the left side of my window, nor can I find in anywhere as I page through the various options.  Help!!!
