Google warning for your premium site

Hi,

If you click in the premium link that links to plugintest.codiixx.com, google says :

“Attackers on plugintest.codiixx.com may trick you into doing something dangerous like installing software or revealing your personal information (for example, passwords, phone numbers, or credit cards).”

Google Safe Browsing recently detected phishing on plugintest.codiixx.com. Phishing sites pretend to be other websites to trick you.

Have a look at this link:https://www.dropbox.com/s/9im4zg5cn1lgq4x/site%20warning.PNG?dl=0

Can you confirm why this is happening and that the plugin is safe to use in production?

Thanks a lot.
