Hi Jorge, I'm very sorry to hear about this. I can tell you that it has personally happened to me as well. There are several Q&A answers on this topic but the bottom line is you will need to contact Microsoft by phone or with a support ticket to get this resolved.
Azure is very strict about any VMs running malicious code.
For me the issue was that I was taking a pen testing class and I unknowingly installed some attack simulation tools which Microsoft flagged as malicious.
Here's a link to another ticket asking the same question and the advice that was provided:
