New computer w/ Norton installed...Can I get a registration # w/o switching to Comcast version?

I have a new computer with Norton installed...Can I get a registration number without switching to Comcast version.  I have the Comcast Security suite on a couple of other computers and have used Norton free for the first month without installing Comcast Norton.  Can I get permissions registration number from Comcast that will allow me to just keep the current version that it installed on my Windows 7 computer?
