Registry Chage, says Spybot S&D

This is the second time in as many (weekly) scans that Spybot S&D has come
up with this entry:

Windows.Explorer: User settings (Registry change, nothing done)

HKEY_USERS\.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Policies\Explo
rer\NoLogOff!=W=0

The first time I just let Spybot "take care of it", but it's reappeared.

In real world terms just what has been changed, and what could be causing
this change?

Rather than have this appear in every scan I'd like to have Spybot just
exclude it, but I'd like a second opinion before I do that.

FWIW, the drill around here is that before I run SB I run AdAware, and
AdAware didn't catch it. I also run TeaTimer, which I believe should have
warned me (and in the past has warned me) that some event was trying to
change the registry.
