My ESET poped up this on a site I maintain and we use OpenX to deliver our ads. We checked and it appeared it was not due to a breach of our openx account

Object: http://d1.openx.org/ajs.php?zoneid=xxx&....

Threat: JS/Kryptik.AGC trojan

Information: connection terminated.....

Now I am getting a 503 error from d1.openx.org when trying to load ads. Was wondering if anyone else noticed this or has any info.

Thanks
