Within the past few days, I've noticed that while browsing a variety of websites, from my Blog, to StatCounter.com, to Scott Hanselman's blog, that an Information Bar was popping up in IE7 stating the following:
This website wants to run the following add-on: 'QuickTimeCheck Scriptable Object' from 'Apple Computer, Inc. (unverified publisher)'. If you trust the website and the add-on and want to allow it to run, click here...
Now, I'm kind of against installing anything that has "Apple" and "Quicktime" in the same sentence, especially since Quicktime has almost become viral in nature (try installing iTunes by itself), so I just have been ignoring the Infobar.
As it turns out, it's the "Don't Be Evil" folks [Google] that are trying to install this ActiveX component as part of the AdSense advertisements that I (and the other sites) have displayed on our sites.
