Google added a very weird tool in their latest IE toolbar: a software dubbed "Search with Google" (SWG) that defends Google as the default search engine. And there's something wrong with this tool, as my investigations have shown.

That's interesting. It's a bit like whenever you install a browser, it always asks if you want it to be your default browser.
