going from regular antivirus to netbook antivirus on netbook?

hi all.

 

I have a gateway netbook, LT2802u with an Atom N455 processor.

 

it came installed with,, as far as i can tell, the
regular norton antivirus program one month trial.

 

I read SO many good things about the "netbook" version, 2011 netbook version.

 

how do i "convert" from the trial regular to the netbook version?!  i see that there is an option for another month or two extension on the "regular".

 

and...bestbuy gave to me a box for regular for six months free trial, a cd version, no less, i have no cd drive.

 

so what, please, people, is the best way to convert to the netbook version?

 

do i wait till the trial expires then buy or download the netbook version?

can i uninstall right now, part way through the month free?

 

and just how much "better" is this version formy netbook?

 

thanks all, on this small confusing issue.
