Hello @Mike Mattheus and thank you for the report.
Please note that this is the service that will handle the PBX updates. I will ask you to also open a ticket to the Technical Support as we will need you to provide us with some more information.
Also please proceed reporting to the Antivirus Vendor from your side.
We are marking this alert as False Positive, as we have not received any confirmation or response from the vendor. At the moment we have not received any other report from any customer.
Please also ensure that you have also contacted TrendMicro from your side.
