Just had the same problem on a computer at work.
they do have a Microsoft logo on it ,so it looks legit at first glance.
It got around Norton on this PC, but it looks like the virus definitions had'nt been updated in about a month.
The more you try to get around it's defenses to attempt a removal ,the more embedded it becomes!
I had to format the hard drive on this one and reinstall all the software.
It appears it was attached to an e-mail from our site from a customer inquiring about a used car,and got around multiple firewalls!
