Login Wall Hack

I noticed a large amount of search inquiries for my website on Google Webmaster Tools that should not be there.

Upon logging in to the backend, I noticed a plugin that should not have been there – I’m the only one with access other than one user who is a family member that never logs on.

It was called Login Wall. I searched this and found a few other WordPress users that had also been plagued by this plugin. It was causing a redirect from Google to a spam site.

It seems as though the redirect is no longer working after I:
Deleted this plugin
Deleted a suspicious PHP file named editor.php that started with:

<?php

$password = "9d62744001ab1ca16e0da793cb89366c";

define('VERSION','kaylin');

 $register_key = array
(
	array
	(

Then I manually installed new WordPress core files.

However I still cannot see the dashboard or plugin menu. I also do not have “permissions” to delete or install plugins from the backend and I have administrative access (100%). I even went into SQL and changed the user permission setting to no avail.

Does anyone have any previous experience with this hack that could help me?

Thanks in advance!!
