I dowloaded my new Norton Antivirus 2012 last week as my previous one was due to run out on the 24/11/11. A sign has just come up that my computer is at risk and not protected, I am not real computer savvy and I don't know what to do now...when I open up Norton Internet Security on the bottom bar and at the bottom of the box to check for newer version it tells me that I have the latest Norton Antivirus 2012 already installed on my computer...I'm very concerned that I am not protected. Can someone please advise...thank you in advance and any help is appreciated..
