Hola Nicomariani
Normalmente google no suele fallar:
u0s.ru:8080
El primer resultado es este tema, el segundo no aporta nada, pero
en el tercero ya tienes información de tu problema y un enlace al final que te puede interesar:
You can find the clean up instructions
Parece que ese enlace está roto, pero una búsqueda en ese blog nos
lleva a él y a su receta:
Cita: How to clean up?
1. Start with your own computer. Scan it with anti-virus and anti-spyware tools.
2. Once you are sure your computer is clean, change all site passwords. (You might want to change computer and network passwords too.)
3. Now keep the new passwords secure. Don’t use auto-upload features of your web site editors. Enter passwords every time you upload new content instead. Use SFTP instead of FTP if possible.
4. Now remove the malicious code (the iframes) from your files on server. The easiest way to do it is upload a clean content from a backup.
5. Scan your server directories for any new/suspicious files (don’t forget to check hidden files). Remove anything that should not be there.
6. If your site was flagged by Google, request a malware review via Webmaster Tools.
7. Regularly check your site with diagnostics tools of your choice (my Unmask Parasites can be one of them) to be sure your site is clean.
Suerte.
