Info on NIS 2010 Add-on Pack

I'm currently using NIS 2007 and its Add-on Pack, and although 2007 is heavy on the system resources it is keeping the web pages I visit and my pc clean.

 

I'm interested in NIS 2010 and hopefully it is good. But what about Add-on Pack for 2010? I think there is one but I don't know what it offers. Does it have ad-block and antispam? (I care not about parental control.)

 

I have searched on Symantec's site for info but I could not find any.
