Will move this to the right place once I reply.
Open up your control panel.
Under "Display Options" there is "General", go there.
Click the + beside "Who's Online"
Find the line that says "googlebot" (I believe that's what it said, I fixed this for myself a long time ago)
Change the right side of the = to 'google' only. Submit the form and return to the who's online page and you should be set
Another option is to add a new line similar to the following
Google Ad Bots=mediapartners
which would differentiate between the two bots
