We broke the story on Mashable’s ad server Eyewonder that impacted popular sites like icanhascheezburger.com and others. We cannot tell if the problem is an ad server or a sponsored vendor link on the site causing the Google malware warning, and it’s not the first time we’ve seen it on Geekestate, and unfortunately we take the warning seriously enough not to go snooping around.
You can get more from Google’s blog here on malicious warnings posted by Google. We are following up with Zillow.
Follow up: It appears that Zillow.com servers are operating normally, including the Zillow blog itself at this time, although we have not tested Mortgage Market Place or other parts of site.
