Utilities or Systemworks? I have NIS 2010 so utilites perhaps?

Looking at the features that Systemworks has should I just get the Norton Utilities since I have Norton Internet Security 2010?

 

I just need a program that allows me to scan and fix registry errors, missing shortcuts, invalid program files as well as cleaning the internet cache etc.


I had Systemworks + NIS 2009 but I believe my time was up for Systemworks.

 

Anyways cause Systemworks includes a Virus protection thing doesnt it?  So again if I have NIS 2010 should I just get the utilites and save like 20 dollars? Or if I have NIS 2010 would I be even more protected by getting Systemworks.

 

I want "complete protection" and  "ability to scan and fix errors"

 

Thanks
