    sorry i forgot to add that this is inspite of running a full scan multiple times.. on one of the machines, i had to reinstall norton trial and have it remove the virus, but its not possible to do this on all infected machines..

    Hi!

    This is hard to troubleshoot. I would contact Microsoft support, they will help you (i won't promise anything but they will probably help you fro free since its a security incident).
    If you can get your hands on a sample, please upload it to Microsofts AntiMalware portal so they can analyse and create definition files.
