I am really confused, and would love to get educated by everyone here and to gain some clarity. At the moment I am using Vista Firewall. But I have heard that it doesn't contain 2 way protection and doesn't contain HIPS. So I installed the FREE Sphinx Vista Firewall Control, only to learn that it doesn't support scvhost and core protection. So I uninstalled it. But then I thought to myself... I don't even understand what all that means? Can someone explain to me please, in basic layman terms.... what exactly am I at risk of happening by using the Vista Firewall? What exactly can happen to the core, kernel and scvhost? What exactly can "go out" of Vista that Vista Firewall will not stop? Thanks so much.
