AM I paying for Norton??

Bought a new laptop and it had Norton Internet Security installed.  In the meantime, I had received a "free" year of Webroot with the purchase of laptop.  Unfortunately, the WEBROOT was causing issues with video/chat feeds.  so, I uninstalled it and I guess I tried to activate the Norton.  Seems to me it activated, but it never asked me for payment, and now it says I have 366 days until renewal.  Huh?  I don't want any surprises here - Also, apparently, I've purchased Norton subscriptions years before because when I entered my email address, it pulled up my "account"  Showed expired subscriptions  - but it also showed my new subscription until 2014.  How am I getting this?  Did it try to charge an old visa card?  How would I know and how would I know the cost??

 

Help!
