Sorry, folks just had to mention this…Too funny!
Google had a hiccup recently, where almost every single search result (including its own www.Google.com) was giving out the "This site may harm your computer" notice.
From the great Stop Badware site:
Users who attempted to click through the results saw the "interstitial" warning page that mentions the possibility of badware and refers people to StopBadware.org for more information. This led to a denial of service of our website, as millions of Google users attempted to visit our site for more information. We are working now to bring the site back up. We are also awaiting word from Google about what happened to cause the false warnings.
Check out Google’s official response to this hiccup.
