I apologize for the inconvenience.
If you receive a deceptive site warning, it means that google has flagged the site due to some suspicious activity. What you need to do is to reach google service using the webmaster tool from your specific domain name (please see more on this article - http://hc.imcreator.com/en/articles/2873539-webmaster-tools).
You might received a warning message on webmaster that's indicating the site that's causing this issue. Please send us the information so we can remove the specific site and account on our end.

Another option is - Changing the label domain to a different domain name. Please let us know if you want to do that.
