How to uninstall Comodo Network Service

I had a friend to install CIS FREE in a Vista 64bits machine today helping her over the phone ,but due to linguistic differences I did not understand that ‘servicios de red’ really belonged to the Pro,so i said ok to installing it. Now i’d like to get rid of it without having to reinstall.
Is it enough to stop&disable the Comodo Network Pro Service in Services, or should i investigate further? Or reinstall CIS altogether?
thanks for a prompt reply: I need to act in 10 hrs time! ;D
