Norton symbol

I received my computer last week and accepted the preloaded norton...when I did a yahoo search, there was a norton symbol beside each of the searches that was listed, as to let me know that that link was verified and safe by norton.....now I don't see any norton symbol at all when i do a search....is there a setting that i need to do to have this be an option or is it just an option the first week you are a norton subscriber?  please help!   i do not want to get a virus on this new computer....as the whole reason I bought a new one is due to a horrendous virus on  my netbook.
