How does Parental Control blocked websites list get updated?

Under NIS 2009 settings screen, when I click on parental and privacy controls, and then click on the  help question mark to the right of parental controls, one of the paragraphs reads:

"Symantec updates the list of blocked sites regularly. Run LiveUpdate often to ensure that you have the most updated list."

I remember when I first downloaded the  Norton add on pack with parental controls, I downloaded the updated list, but that was over a month ago, and since then I have not seen anything when, I run live Update, about parental control blocked websites updated list being downloaded. 

How often is it updated, and when it is being downloaded, what would it show up as?

also is there a file under norton or on my computer that would show  that the updated list  was downloaded onto my computer, so I know I have the current list?
