I have several sites hosted with Hostmonster. Link spam is added to all of my sites' wp-blog-header.php files and displays after the closing HTML tag on all of the site's web pages. Here is a sample: http://empoweryou.ca. As soon as I remove it it reappears.
And I keep getting an admin account added under the name doctor9. I delete it and it reappears.
I have asked Hostmonster support for help and they refer me back to WordPress.
I am using the latest version of WordPress and all plugins are regularly updated to the latest versions.
Is anyone else having the same problem?
