200mb live update?

Is a 200mb live update unusual or is it normal?

 

I have over 200 days left on my subcription, the last time I ran live update was yesterday( It's almost always the first thing I do once my computer has started up), I have the latest version of NIS(I did a new verion check right before I posted)

 

When I open NIS everything seems normal. It's not telling me my computer is at risk. I've tried rebooting, I ran a quick scan to see if it worked and to see if it could find anything. Everything ran as it should and all if found was tracking cookies.
