NIS 5 for 10.8 Install

Trying to install NIS 5 for mac 10.8 and keep getting message:

 

Norton cannot be installed on this disk because the following incompatible product(s) are installed:

Norton  Internet Security

 

You must uninstall the opther product(s) before installation can be performed.

 

I uninstalled the prior version and did a search on the computer for anything Norton...nothing comes up.  Any ideas?
