Reinstalling Norton Security

A few days ago, I had to do a system recovery on my system.  When complete, my Norton's was gone.  I went in to change and I think it has been reinstalled, however, I don't see the Norton Logo on my desktop.  When I go online, I don't see any Norton logo.  When I go into my control panel to check for problems, I keep getting a message that I have no protection.  I don't know what to do from here.
