Recommended way to uninstall NIS2012 prior to installation of N360?

Hi,

 

My brother bought a new computer and I want to install N360 on it (since I bought 3 licenses some time ago). Unfortunately the computer came preinstalled with a 90 days trial of NIS2012 so my question is how do I uninstall this properly?

 

I found the following procedure, but it was posted last year - so I was wondering if it's still the correct way to do it:

 

1. Download www.norton.com/nrt for NIS

2. Remove NIS via Add/Remove program in control panel and reboot

3. Run the removal tool and reboot

4. Repeat step 3, 2-3 times.

 

I just want to be 100% sure since I don't want any mess with anti-virus software :) Thanks in advance.
