Darn. I've been going over this myself whether to use Comodo or Online Armor Free, but you guys are making me lean towards OA, especially with the registry thing, but I've been working on resolving that. The main reason I'm using Comodo is because of the outstanding HIPS protection, which hasn't bugged me much, but if OA's is as good, I would probably use it. However, I noticed I have to register to use OA, and it doesn't have automatic updates. These are minor inconveniences, but still.
