My husbands computer was infected with this virus.  I downloaded Norton Eraser and Bootable Recovery Tool to CD and ran them both.  I also changed the BIOS to read the CD first. After running it says no files are infected.  Now when I turn on the computer the administrator password comes up then the DOS screen just keeps scrolling down. Norton said to contact "Norton Virus Removal Assurance" and for a fee they may be able to help. I am getting all my Norton downloads and information from my computer because I dont have his Norton Information or product key code since the computer is infected. Does anyone have any answers to help me out?
