Google has been displaying a Warning: Suspected phishing site!message for websites that use the Google Ad Services code on their website. This happens only when users are using the Google Chrome browser to browse to the site.
I came across a very popular site called Venture Beat that may be affected by this problem, take a look at the screenshot below, this was taken while browsing to Venture Beat using Google Chrome Development version.
I can confirm that this also happened on a secondary PC using Google Chrome. In addition to this Google has also been blocking it’s own website Google Ad Services, take a look at the screenshot below.
I am not sure how widespread this issue is, but this will definitely put off visitors from entering your site.
