Between 6:30 and 7:25 am PST, every single search result on Google was met with their dire warning that "This site may harm your computer!".
So what happened?
Most programmers will nod and smile when they hear that the value "/" was listed as being a site containing malware. For the uninitiated, a / is basically added to the end of every site's URL and it expands to all URLs. So all those Google links got tagged as bad when they were, in fact, just websites.
The Google Blog has the full deal. But really, from the perspective of someone who's done web design and programming, it's nice to see the big guys screw up every now and again.
