My computer crashed so bad I couldn't even get to Norton's support page. Had to use Geek Squad

I tried getting to Norton's support link.  I tried looking for Norton's telephone number.  I gave in.  The $19.00 per month I have been sending to Geek Squad saved my sanity while Norton's support system did squat.  I called them up (couldn't use my computer so I had to call for help the old fashioned way) and they immediately went about fixing my system.  Guess what?  I had a virus and malware on my computer.  All this time I figured Norton's would protect me.  Tell me again what your product actually does?
