Unable to virus scan

I am currently unable to scan my computer with my NIS, It stays at 0 Files scanned and won't move on.. 

 

I am also getting a thing that says I need to "Fix now" when I start up Norton, So I'm assuming I have a virus and I can't scan to get rid of it.

 

Any Help?.. Also sorry about not giving more information, I don't know much about it.. but just ask if you need to know more.
