I have a message saying 44 items on my computer that can infect my computer, its some type of virus and the norton antivirus thing keeps popping up but I have to pay 44 dollars to use the norton virus thing to get rid of the 44 items of potential threat items.

Do I just by a norton antivirus from a store and this will go away or is it more to it than that.

For the time being I have to use the computer at work the the home computer hasn't been turned on in 1 week until I get rid of this virus threat thnig.

HELP ME>>>>>>>>>>>
