I've been trying to find a solution for myself to lock down my system. I would like to use a HIPS solution. I tried threatfire at level 4 but it made my computer very slow on startup and would spin my drive a lot, I could hear it, on occasion if it became at all unresponsive it would cause system instability as well. What I wanted to know was how/why some HIPS are better than other HIPS. Don't they all lock down the applications allowed, lock down registry and startup settings? Which is the most comprehensive? Or do different HIPS protect different things? I've done a lot of reading, I was eager to try EQsecure but no english, so I'm leaning towards trying Defencewall, but I don't want to keep clogging my system with stuff I'm going to uninstall.
