It does, the process is the "antimalware service executable" and I find it can occasionally start running while I'm in the middle of trying to do something else. I notice it right away because the fans on my laptop will spin up to max speed for a few minutes, even if I'm just doing something basic like editing a document. I'm not sure why it tries to run what appears to be a lengthy scan when it can see the machine is not idle.
