So, I submitted the suspicious attachment I received to virustotal (scan@virustotal.com with SCAN in the subject and suspicious file as attachment.) What follows below is the report I received. It looks like some of the big names (Symantec, McAfee are not finding anything wrong with it at this point, with the hodge-podge of names it will take me a bit to investigate and see if the other vendors are tagging it as new.)
