Does nav or nis 2010 scan my incoming and outgoing email?

Got a question,

 

If I have Nav or Nis 2010 on my desktop, will it automatically scan my Outlook Express email both sending and receiving, without my having to install the Anti-Spam and Paraental controls which are optional. I dont see it scnning my email right now.

 

Tnx,

 

Alex :)
