If you are running Windows, try the one from Microsoft or AVG.

and start up whatever directory browser they provide. Once it is running, make sure that you select "view hidden files". If you dont see that exactly keep looking - it probably has something close.

You will probably see a file called .htaccess right in the root directory. This is the culprit. It must be deleted. It is redirecting requests comming from the search engines listed in the file. You can look at it's inards before you delete it but delete it you must. Then hunt through all sub-directories for anything that looks suspicious or duplicates of the .htaccess file. You may see a zip file somewhere as well.

Do you have a Wordpress account? Or do you have a Wordpress blog? I think that this is spreading like wildfire through thier servers and infecting linked domains.

Yes - spyware or malware software is highly recommended as well. Spybot search and destroy is good and it is free.
