You might have to do more cleaning. Be sure that the rest of your site is sanitized.
Make sure your own or other people's computers (with site admin access) are clean too.
You might be able to block the site listed in your iframe contamination. It is listed on Macafee as the source of malware.
The listing is obscured here for obvious reasons. -c-c-f-e-l-o-m-v-h-k-.-c-o-m-
(remove all dashes)
Block the site and also the ip address for the site. On your computer too.
This won't cure your infection, but might help to slow them down a little.
Ive cleaned out everything I thought it might be. Any suggestions.
Check everything as instructed
