Is this fixed?
The problem sometimes originates from a trojan on your PC, that will use your ftp login to upload modified and infected files.
The only way to get rid of this is to get your PC clean first.
You also better change your ftp password ASAP because that has been compromised.
And if your ftp program has the option to password protect the logins/site manager then better do so.
Pretty tedious. Just be careful that you do this while offline if you want to check the pages in a browser.
It just downloads trojans from other sources. If you're offline it can't.
So you can just remove it.
Just reuploading your files is not gonna solve it, you have to check each and every one of them.
It might be a good idea to talk to your host and ask if they have been hacked recently, that's another way in which this spreads.
I didn't see your site so I have no idea what it is, html, php or whatever. If you're running Wordpress or any other CMS get the latest update before reinstalling.
Some of them promise a lot and deliver even more!
