Just brought NIS 2009

Hi everyone,

 

I just brought NIS 2009 on eBay.  I downloaded the trail version of the program from here and used the product key that was email to me from the guy I brought it from on eBay.  It's a 2 year subscription and it says I have 731 days remaining aftered I entered the product key.  I have a couple of questions.  

 

1)  Since the product key worked, I take it my subscription is valid, right?

2)  When NIS 2010 comes out, will the live update automatically update my current program?

3)   Before when I had McAfee, when I did a full system scan, it scan like 400k+ files but for NIS 2009, it scan between 200k - 300k files.  Does this seem correct?
