  1. Opened that attachment & norton360 missed it. Who knows whats next. Even scanned the folder with norton. Reported to adp. Cant find the folder now. Doing full scan.

  2. I passed the whole thing on to abuse@adp and got an instant acknowledgement showing they were already aware of it.

  3. We received the email today and I ran it through Virustotal and only 8 out of 46 detected it for me. Wonder if it’s been modified since this post.

    • It is always possible that a new trojan variant emerges and that the anti virus engines need a new update. This will of course result in a lower detection rate at Virustotal.

      • I tried to scan again today and 24 were identifying it now, including our office AV, Symantec. We did a scan and it quarantined and deleted the file. Hopefully that’s all that was needed, but who knows!

  4. I have received this type of email twice. I haven’t opened either, but I cannot delete the latest one. When I try to do so, I get a message saying that the message can not be moved to Trash because “101630.emix” couldn’t be copied because you don’t have permission to access “Messages”. Anyone have any suggestions how I can delete the email?

  5. RE: SJ Williams: if you’re using outlook or outlook express as your mail client (instead of your browser, like yahoo or gmail uses) then simply hold down your shift key and hit delete while having the message highlighted. This will “permanently” delete the message without trying to send a copy to your deleted items folder (causing the problem for you).

  6. Very useful info, thank you! This was the first website I looked at when searching for info on the email I suspected as bring SPAM.
    Also forwarded the email onto

  7. I received this virus email from There was no attachment, and my Outlook thankfully didn’t auto download any of the images on the email. Hoping that just opening it didn’t set anything off. The subject line was “Payroll Invoice” and the inside of the email was pretty much the same as above.

  8. This one arrived in my inbox today and I almost opened it! I am concerned that the normally efficient filters didn’t pick it up… but have forwarded to and deleted from my system (I hope)!

    Thank you for keeping us all alerted.

  9. This post saved my bacon today… 3/6/13. Thanks! I run WebRoot and could not get it to scan this file nor detect a virus present… I did NOT open. Thanks again!

  10. Thanks for this information. I have received this email and because I have recently done some work for a new organisation, I was unsure as to whether or not it was genuine.
