I never misunderstood anything. A clean system means that it is free of malware, not by your definition.
Once again, a background process is hanging up the system, when it goes into shutdown. It could be a task, it could be something that is running that you thought that you closed, but there is a cosing problem.
You are going to have to go through and diagnose to find out what the exact process is that is causing this. None of us have any way to tell you, because not every system with this kind of problem, is going to be the same.
