I have Voodooshield. Is OS Armour a similar product ?
The protection of OS Armor depends on rules and it is monitoring the behaviour of processes.
It monitors the system for suspicious processes/processes in suspicious folders and suspicious command-lines.
If you have an Anti Executable installed, try to execute "unknown" applications and you will get an alert about the execution.
OS Armor wouldn't give a peep. Only if one of its rules gets triggered.
If applications like: java.exe/mmc.exe/mstsc.exe are about to launch other (legitimate or whitelisted) applications, the Anti Executable wouldn't give a peep.
OS Armor would block it, if the according options are checked ("Block any process executed from mmc.exe (unchecked by default)", etc.)
If you want to have full control, use an Anti Executable.
But OS Armor provides an additional layer of protection. It has no complex configuration ("zero-configuration") and right after installation it is protecting without annoying prompts. (credit mood)

OSA "Anti-Exploit" protection isn't a real anti-exploit like HMPA or Windows Exploit Guard, it doesn't act in the memory, it is just a simple post-exploitation mechanism to prevent the listed apps to be compromised. (credit Umbra)
OSA is just a simple nicely made anti-exe with built-in rules, its scope is to prevent exploited processes to do more damages. It is a post-exploitation software. (credit Umbra)
