norton 2010 to norton 2011

Turned on my computer this am and i had a norton message asking if i wanted to upgrade my noton 2010  (which i bought late last year) to Norton  2011. I did so and all looks fine and seems to be working but the paranoid in me just wants to check that this was a valid upgrade and not me downloading some dodgy malware. Can anybosy confirm that Norton are doing this upgrade?

 

thanks
