Your site appears to have been hacked there is no favicon or hacked favicon.ico file and there is a call for that which generates a 404 error page which has most certainly hacked, http://www.virustotal.com/file-scan/report.html?id=df15fc444d130b29c31f1a48d382f3f2072b84668b4d5976deb98aef8e82cdd3-1307985672.
Other image files also appear to have been hacked.
