up all on its own, asking me if I want a software update that improves
the security of the software update process. 

Nice... but why would you want to update Apple (OSX) Software Update.... on a Windows box? Heh. (on 2nd thought, it could be something iTunes might do... dunno since I don't do Windows. If you're not sure, you can always dismiss the popup and go launch any updates from within iTunes' own menu). /P
