36 DAYS LEFT OF SUBSCRIPTION

I have Norton Security Suite Through Comcast.

I download a free tool from Norton called NORTON PC CHECKUP.

After running the tool it states in the PROTECTION SECTION:

Product Name ---------Norton Security Suite

Subscription Status---------36 days remaining.

 

Why would would it say I only 36 days left on subscription especially since I only started this software on 07/22/2010?????

Can someone give me a reason for this?

Thank you
