Norton says I have Zeroaccess.c Norton Bootable Recovery now hung

Norton 360 says I have zeroaccess.c and zeroaccess.gen2

Ran Norton Power Eraser with nothing found

Now ran Norton Bootable Recovery Tool and after a few hours stalled, left overnight, still stalled at same point, tried to cancel scan as no viruses were found by that point, cancel also stalled now for several hours, can't get out of it

How do I break out of Norton Bootable Recovery Tool?  Turn off?  Key combination to hit? 

Looking for help from someone in the community that can help me break out of Norton program and ultimately remove the trojans

Needs more than what I can do with the symantic recommended removal
