Installing NAV on a system that had McAfee before..?

If I buy a new laptop which as you know, 90% of laptops these days ship with the crappy McAfee Internet Security preinstalled.

 

Is it ok if I uninstall McAfee, then restart, then run the McAfee Uninstall Tool, then install NAV?

 

Or is it better to format and do a clean install of NAV?

 

Which in your opinion is the better way to go? or is it the same?
