Update: Stopbadware which works with Google to identify troublesome sites has a blog listing the events that led to the glitch.
Update: Google is blaming its calling everything malware glitch on (wouldn't you know it) human error.
I wrote a quick blog earlier about my finding that nearly everything I was searching related to the superbowl was being flagged by Google as a security risk. It seems Google was flagging everything as malware. It would be nice if Google would explain the basis of the glitch but I'm not holding my breath.
