My McAfee web advisor has been installed but it isn't working.
I added the McAfee web advisor extension and enabled it in private browsing. The icon shows up green but it doesn't work in Google searches.
Additional System Details

You might need to change a setting. Click its toolbar button, then Options. Then select "all search engines" and you can close the dialog.
Most of the time, it doesn't seem to mark results at all, but they approve of Wikipedia and their own website. ;-)
