Norton Insites Results

I ran Norton Insite Program.  I am most concern with is the section that lists Good Files 606.903,700 and Bad Files 428,808,056.  OMG the number of bad files really concerns me. 

How do I deal with the 428.080.056 bad files?  Can they be cleaned them up, can the be repaired, or is there a way for me to them? 

I would appreciate some direction regarding these bad files.

Thank you,

Manny
