PC not protected by SONAR Advanced Protection

Hi...I'm new with Norton and not THAT great with computers. I just installed Norton 360 (I was having problems with my searches in Firefox being redirected, which Norton didn't fix, but that's besides the issue right now I guess) and I am getting an error message saying "Your PC is not protected by SONAR Advanced Protection".

 

I've never installed this, let alone even heard of it. Any suggestions on how to fix this?

Minipug06:

 

What  security was on your system before you installed N360?  Did you use any removal tools to clean off the old program?  Do you have any other antimalware scanning software like Adaware or Spybot on your system.

 

Please run a Hijackthis log for us to see what can be corrected before we look at other corrections.
