Norton Internet Security 2012 Pre-installed want to use 360

Hi, I just got a new laptop today and it has Norton Internet Security 2012 pre-installed. I have not even turned it on yet and wanted to get some info first.  If I want to purchase 360, do I need to uninstall the Norton Internet Security 2012 even though I haven't activated it yet?

 

Also, I noticed on the 360 free trial page it has instructions for IE and FF, but not Chrome. I prefer to use Chrome, but if it isn't compatible I'd like to know.  Thanks for any help!
