"Some pages on google.com contain deceptive content right now."
Thanks (and no thanks) to malware sites that use keyword to trick Google to place them to higher rank and Google cannot completely eliminate them from the result, the status describes the status reflecting reality. The bottom of the page actually included some of the links that users reported to contain those contents - since Google displays result in form with redirecter link that originates from google.com ( google.com/url?... ), those malicious contents are counted against "google.com".
On the other hand, Bing shows result URL directly so does not suffer from this problem.
And there are "dangerous sites" that sends people to google.com, including Blogspot one that I presume is using Google search functionality to replace it's internal search function.
