Joomla Site hacked. Search engine result listing is redirected to spam page.

When you click on the link to my site, it takes you to a spam site. There's a topic about it here: http://forum.joomla.org/viewtopic.php?f=432&t=486377&p=2158541#p2158541

I did these steps in the security checklist 7:

* Ensure you have the latest version of Joomla
* Review Vulnerable Extensions List to see if you have any vulnerable extensions and deal with them.
* Review and action Security_Checklist to make sure you've gone through all of the steps (please note some steps are optional, but please review them all.) -i haven't done the entire list.This is overwhelming and is making Joomla suddenly much less appealing
* Change all passwords and if possible user names for the domains control panel, mysql, FTP, joomla Super Admin, and joomla Admin password; do change them often. Passwords should be at least 12 mixed alphanumeric characters and contain no common word phrases.
* Do not use the standard Admin user. Disable it. If you need to reset your admin password, see these instructions
* Replace all templates and files with clean copies,
* Check and/or replace all .pdf, image, photo files for exploits -didn't do this. not sure how to check the files-
* Check you server logs for IP's calling suspicious files or attempting POST commands to non-form's I'm asking Bluehost for help with this
* Use proper permissions on files and directories. They should be should never be 777, but ideal is 644 for files and 755 folders.
* Notify your host and work with them to clean up the site, and to make sure there are no back doors to your site. I'm asking Bluehost for help with this

This is intense. Any help is appreciated.
