For those of us who have Norton Antivirus, what would be the best procedure in view of the recent theft of their source code? If we decide to download a different antivirus program, do we download it, go off line, turn off Norton (or delete it), RUN the new program and then go back on line to get the updates for the new program? Of the free antivirus programs, which one(s) are the most effective? I am definitely paranoid when it comes to security. Thank you
