Unwanted Ad Link - bug / malware

Hello everyone,

I’m in the Editorial team of the Community Informatics Journal (http://ci-journal.net/), and, for some reason, an ad link which seems to be in Persian has been showing up at the bottom of the pages and issues. Does anyone know how to fix this bug?

Thanks
David Nemer

It is maybe in your footer in Setup => The Look => 5.4 Journal Page Footer ?

How it got there, I do not know. Is your files directory outside the webroot?
