Is it normal that virtualbox is still running on Windows shutdown?

Hello, I thought I saw this problem discussed on here a few versions ago, and that it was addressed. But I can’t find any mention of it now. Installed a couple days ago and all seemed ok.
However, the last couple times I have used Local, I have had to quit a session (stopping all sites of course) right before shutting down my Windows session. And without fail, I get a message that the VirtualBox is still running and preventing shutdown.
Is there a sort of “best practice” or minimum time lapse that needs to be respected so I don’t have to deal with this annoying message and the uncertainty that all data will be intact?
Thanks!
