Emisoft Anti-Malware + Online Armor was their "Internet Security Pack" as it combined 2 standalone products that ran alongside one another, this was the result of Emsi Software buying Tall Emu (Online Armor) at the time. They have now released their own all-in-one Internet Security.
Emsisoft Internet Security is their new product that combines their Anti-Malware, Behaviour Blocker (Mamutu) and a new Firewall built-up from scratch. I cannot comment whether it implements a HIPS component, but the answers above may provide an answer for that.
