Hey guys!
The last days I cleaned up some infected WordPress Websites.
You have to search for forwardmytraffic.com with phpmyadmin or manual SQL-Queries. In my case there were 4 entries in the wp_options table.
Then just replace the URLs in every entry with your own Website-URL. Be careful if there are multiple occurrences.
After that you may have to delete the cache. If you have no access to the admin-backend, you can try to rename the cache folder within your wordpress installation. You can delete the folder if it works.
