Using Spybot S&D 2.4.40.130 free on Windows 7 x64. I went to the update engine as it had not updated in 97 days. I started the update and left it in the background while working on other stuff. Suddenly various windows began closing left and right, programs put up exit confirmation dialogues which were also closed automatically, and my machine logged off and restarted. I lost unsaved data in at least one application.

Is this forcible reboot standard operating procedure for a Spybot update? Is it possible to convey without yelling how strongly I dislike this behavior even in an operating system, let alone auxiliary software? DON'T REBOOT MY MACHINE WITHOUT ASKING ME. EVER.
