It looks like that Microsoft is unable to help us.
It seems like that it is not a virus, since we did not instal anything before to get this message.
Please let me know if you are interested to help ourselves to find a solution.
We can get dome information together for example, what's kind applications we install on our machines, our machine system and version and locations,
If you are interested for this, please leave message here that we work together to find a solution for this,
Regards,
Souries,
