Yes use the same serial for each computer. Also, the CD version will surely be the old version (newest as of the time of release of the CD). You can download the LATEST version of Norton Internet Securty 2011 at http://www.norton.com/nis11

An added note on top of what Tywin7 said. Even if you download the full version of NIS 2011 from the link Tywin7 provided, be sure to run Live Update afterwards until there are no more updates, rebooting as requested.
Even the link to the latest available full version of NIS will not have all the updates so running Live Update is crucial. Also be sure to run a manual Full Scan after NIS is installed and updated through Live Update. You can do this by clicking Scan Now > Full System Scan from the main NIS window.
Things like the background Idle full scan may not function properly unless that initial manual scan is run after installation.
Hope this helps.
