I suggest that Comodo have a short tutorial on the comodo.com site for new users to read/view before they download and install CIS. I think the uninitiated in firewalls and computer security might be getting a little freaked out by the popups and choices they need to make when first running CIS. Maybe a word on the default settings of CIS just in case a new user is not sure his/her computer is clean, or all its applications are to be trusted.
