NU 15 and NIS 2010

I have Norton Utilities 15 on my machine.  I still get messages suggesting my "computer may be at risk".

 

Does this imply that NU 15 does NOT provide virus protection?

 

If so, what are the implications of re-installing my NIS 2010?

 

Will the two programs conflict with each other?

 

Thanks,

 

Terry
