Actually I am not sure.
She told me that she ran into some problems whilst trying to print a document to her job. It was sort of important and she was stressed up about it, so it could just be that she did something wrong and thought it was a virus - not very tech savvy.
The computer did crash (BSOD), not now, when she was trying to use it. But using the BlueScreenViewer from nirsoft the culprit appears to be the atapi driver (IDE controller).

What about the Gmer entry do you have any idea about what it is?
