I just launched a new web site xxxxx.biz ( .BIZ TLD ) two days ago intended to list my domain names for sale. In the first day, it was working fine but the next day when I tried to access it I got this message: “Deceptive site ahead Firefox blocked this page because it may trick you into doing something dangerous like installing software or revealing personal information like passwords or credit cards. Advisory provided by Google Safe Browsing. xxxxx.biz has been reported as a deceptive site. You can report a detection problem or ignore the risk and go to this unsafe site. Learn more about deceptive sites and phishing at www.antiphishing.org.

But when accessing this web site, it does not show the same warning. Obs: “xxxxx” name here is just a fictitious name in order to protect the real name. 2) My intention was to use this new web site to TEST what, between two different domain names and different logos but with EXACTLY THE SAME CONTENT would attract more traffic. So, it is strange that my other website yyyyy.com has exactly the same content and yet is not flagged with this nasty warning. What could it possibly be ? How to fix it ?
