This was the detected URL:
htxp://wxw.googlecodehosting.net/openx/js/zone_functions.js?cp=620

I discovered that, while it was not impacting my ad-server, that this was indeed suspect code that was inserted somehow into my data.
I’ve now removed it.

This code does not appear to be malicious unless you are using OpenX a certain way. Fortunately I was not doing what would be bad. My customers are safe -but please be advised!
