google safe browsing service is unavailable
Google safe browsing service is unavailable and has not been updated for 7 days. I've searched from the apple forum/communities and could not find a proper solution.
My MBP's running Maverick and I've installed "ClicktoFlash" extension. I've also ask around my friends and they do not have such a message like mine.
MacBook Pro with Retina display, OS X Mavericks (10.9.1)
