Why does my website report "Deceptive site ahead" in Google Chrome?
The "Deceptive site ahead" message from Google browsers comes from Safe Browsing reports that they receive and review. If the phishing attempts were addressed, but the problem is reported and reviewed by Google prior to the issue being completely cleared, then the message will be placed against any domains that are associated with the phishing attempts. Google has further details on addressing the problem here:
There are various steps that Google requires that the Administrator reviews before requesting that their domains are delisted from Google's Safe Browsing database.
