  • Try temporarily disabling your antivirus and then download the symbols again.

    There must be something in the symbols which has the same signature as a virus. I'm hoping that the symbols do not actually have a virus!

  • Thank you for the hint. I've tried that before and no luck. I'm sure there will be another HTTP error code instead of HTTP_STATUS_NOT_FOUND in that case.

  • Yes, it works now. Thank you very much for the prompt response! Now I can dig into the dump.
