Just checking with AutoRuns for Windows and Google Update almost feels like a spyware in every possible place.
It acts as a service so when you turn on your computer it will make sure that its always on. If you somehow remove it as a service, it also acts like a BHO. The next time you start IE it will start. If for some weird reason these two failed its also in the scheduled tasks.
Just waiting till it installs itself as a driver as well.
