It sounds as if your site has been hacked. As well as scanning for viruses, you need to check whether there are any files on your site which shouldn't be there, or any files which have been changed. In particular, I'd check the .htaccess file.
There is a detailed post here about recovering from a hack: http://www.sitepoint.com/forums/showthread.php?634630-Resources-on-web-application-security&p=5324870&viewfull=1#post5324870
