This is NOT someone who has hacked your FTP.
This comes from a trojan virus on your computer that not only screws up your whole computer, denying you access to any antivirus sites and stops all downloads.
It also infects ALL your HTML files on your computer with this little IFrame script.
I basically had to wipe my harddrive clean to get rid of the virus and after getting all my backed up files to my computer again I noticed that I had "infected" my entire website as well the next time I updated it.
The reason for me necro posting this is because this topic comes up as top 3 on Google when searching for "Brenz.pl/rc/".
I just thought the information should be correct.
I hope this helps someone!
