Installing Norton Internet Security Over Systemworks ?

I have Systemworks 2006. I would like to install the lastest Norton Internet Security.

Can I install in over Systemworks or do I have to uninstall all or part of it first?

 

I have XP with all the latest upgrades. Systemworks is version 9. It has NAV, Utilities, GoBack, and Cleanup.

 

Thanks!
