As my name implies, I've become confused. I bought a new PC and removed the installed security software. I then went to norton.com/nis2012 and tried to download a copy of NIS2012. Somehow I ended up getting a trial copy of NIS2013. I uninstalled the trial and went into My Account App and logged into Norton Management. I clicked on the install tab and it installed the full version of NIS2013. Do I need to uninstall NIS2013, run the NRT, then download and install NIS2012? From where?
