I am struggling today with the site, where suddenly to some people it displays porn instead of our content.. so if I scan with the plugin, it finds threat immediately in the wp-load.php file. But after I press fix, it is fixing without error and immediately shows that the file is re-infected. I have tried many times. I also checked the file in server, did not find more differences with original file then that part in the end and I deleted it:
// Edit and deleting this code is not recommended!
@include( ABSPATH . WPINC . ‘/images/tnd.png’);
However, it comes back…Do you have any suggestions what to do?
