What is the purpose for cavwp.exe if you don't have the AV installed?

Let’s say you only have the FW setup with no AV, what is the purpose of that process? Is it just a dangling process with no real purpose? Is there a way to disable it? I liked 5.12 more because it did not have these extra processes. Not that it really matters. It’s just that I am a bit of a process maniac, so I like to have the least amount of them. This may be a dumb question, but I have to ask.
