Symantec Intrusion Prevention Browser Helper Object is listed as Disabled

Quick question related to Intrusion Protection: 

 

I recently reset IE7 (Vista HP SP1) because I was getting frequent program hangs.  Then when I looked at Add-ons (Tools, Manage Add-ons, Enable or Disable...) the Symantec Intrusion Prevention Browser Helper Object is listed as Disabled.  I have it On under the NIS 2009 settings and get a Secure status message.

 

Does this mean Intrusion Protection is in fact working, and does it make any difference to Enable the Add-on?

 

Thanks!
