Saw it on a myanmar blog Degolar first, but I didn't believe it was a Google problem because when I checked Google, I didn't see the problem.
Just read the BBC update a while ago confirming the problem. Google marked every search result with a spyware/malware warning flag "This site may harm your computer."
It's a pretty big accusation to pin on the world-wide-web, the evil deeds of serving up malware. I'm glad they corrected it though. What if everyone believed Google and thought the digital world was coming to an end?

Update: Here's what Google had to say for themselves. Official Google Blog: "This site may harm your computer" on every search result?!?!
