Hi @copenhagen, sorry to see you’ve been having this problem.
If you’re aware that your site does contain malware and can pinpoint any specific files affected that Wordfence is not detecting, we are always interested to receive file submissions to check for ourselves to samples @ wordfence . com to be analyzed.
Ultimately, WordPress can still be affected by an undiscovered plugin vulnerability or a compromized user account, for example with poor password security, despite Wordfence being installed. I will still provide you site cleaning instructions below in case they are required:
https://www.wordfence.com/docs/how-to-clean-a-hacked-wordpress-site-using-wordfence/
Make sure to get all your plugins and themes updated and update WordPress core too. If you are on an older branch (WordPress 4.x etc) because you wanted to wait before installing the latest version because of Gutenberg or a custom theme compatibility you still need the latest update in that version. Those can be found here:
https://wordpress.org/download/releases/
WordPress sometimes patches their older releases if they find a vulnerability so make sure to update your version if needed. We, of course, recommend that you update to the latest version.
As a rule, any time I think someone’s site has been compromised I also tell them to update their passwords for their hosting control panel, FTP, WordPress admin users, and database. Make sure to do this.
Additionally you might find the WordPress Malware Removal section in our free Learning Center helpful.
If you are unable to clean this on your own there are paid services that will do it for you. Wordfence offers one and there are others. Regardless if you choose to clean it yourself or let someone else do so, we recommend that you make a full backup of the site beforehand.
Thanks,
Peter.
