Does UTILITIES ULTIMATE and ERASER WORK?

I installed 360 and ran a scan. It says I have 5000 performance issues, 175 broken registry items, and 30 broken shortcuts. Really? I just installed it on a brand new machine - nothing on it yet, just windows and a browser. The reason I’m doing that is NORTON ERASER ate the CONFIG SYS file, on two machines, rendering the drive and the system useless. My computer guy can’t fix it, and he’s near genius level. I will never use eraser again. But so many problems on a clean machine?
