Susawx, I'm sorry you are having to go through this, but yes, I think we fixed it. I'm sad to say the only way you will get rid of this one is to go through your site directory by directory.
We found a couple malicious php files, one in particular named wso2.php, which returned our passwords and directory mapping information, and then added links to our page if the site was viewed through google. That allowed the hacker to overwrite a few different files that we found over the course of a few weeks. Here are some starting points to getting rid of it:
1.) Check you administrator/index.php file. Ours had a script that returned our passwords to a specific email address.
2.) Then change all your passwords.
3.) Check your other directories to see if any changes to have been made to permissions. If there has been changes, that will tip you off to where they are overwriting or adding files. You'll probably find something in those directories.
4.) Change the permissions of directories to 755 and all files to 644, no matter what.
5.) For a thorough investigation, take a Joomla install package that matches your version and compare that package file by file to what you have on your server. Extra files that have not been installed by you or components you are using should be discarded.
6.) Take that install package and overwrite your web server files, and this will most likely at least temporarily fix your problem with Google. I also recommend adding a sitemap through Google's webmaster tools so that you can better control when they update the cache of your site.
That's the Joomla side, then there is hosting issues. Check your ftp logs first and that will let you know where the hack is coming from (any i.p address listed that isn't you). Ask your host to blacklist that I.P. address.
Then change your passwords again to be safe. You can also invest around $60 into RSfirewall (which i did) for better security. I installed that and have been happy with it so far.
I know that is exhaustive, but it is definitely an exhausting situation. Hope that helps.
