Wow. I just got the FBI Greendot Moneypak virus

I need help with this.  I figured I had something like this when everything locked up but could not access another computer.  I got in safe mode and did a little research.  It got by my Norton suite provided by Comcast.  I have everything on auto update and still got it.  I am running the power eraser on the machine, but shooting in the dark here.  Any help would be appreciated...

 

I got the results of the Power Eraser.  There was 2 items to remove automatically and several other items it was not sure about.  How do I know if I have gotten all of the virus removed.  I have read there are many different things is various places to remove.  I am and old guy who used to know computers back in the day of COBOL and FORTRAN, but I am a real newbie again with all of the technology these days...Kinda wish I would have bought that Apple computer now...
