If purchase new computer with too many free norton/symantic preinstalled trials and offers

Just in case a new computer comes with more than one Norton preinstalled product and offers for others, do we need to use the/a Norton Removal Tool in order to remove or uninstall them, before installing the product that we WANT?    I see some specifications for new P.C. Windows machines that come with already present trial versions of PC Checkup, Norton Utilty Suite, and Norton Internet Security, trials.  I would want instead to run an installer for Norton Internet Secutiy to use as a SUBSCRIBED product.  In fact, a new p.c. may come with Norton 360 pre-installed but I would probably already want to run the installer for NORTON INTERNET SECURITY, which I may have either newly purchased or freshly downloaded from Symantec. 

 

What would I need to do?
