Get Off Those Maliciously Loaded Scripts!
Download this free Anti-Malware Plugin for WordPress.

I have added this script to my definition updates.

I just want to point out that this is ad code from a legitimate ad network, that is being used in this particular case by a user of their services to promote ads on your site without your permission. While these ads were injected into your content maliciously and without your consent it was not the fault of the ad network, however I do feel that they are partly responsible for allowing the misuse of their ad network to promote their ads on sites that have not given consent. It would be wise for them to require verification of consent by the site owner before rendering ads on their site.
