I've been working on a huge plugin update that will fix this problem. Recently, this plugin was targeted by some ad blockers, and it's been causing havoc. One of the changes will stop this exadwese.us iframe call.
It wouldn't surprise me if someone purchased the originally unused domain exadwese.us and started serving up malware. There are a handful of very militant anti-adblocker-detection advocates out there that wouldn't blink at doing this.

The update is huge because it had to address numerous problems at once, but the majority of it is finished. I just need to polish up a few things, stress test it, and update documentation/instructions.
I expect to have it released in not too long.
