Microsoft Dynamics Customer Insights URL identified as phishing sheme

I have a Microsoft Dynamics Customer Insights Journey (Marketing) PoC.

The links in the email that was sent out from this environment ran perfectly a week ago, now when I click the links in the email, I get a threat detected message form Avast Premium, stating that the link (Microsoft default domain for Marketing trials) from my PoC is infected with URL:Phishing.

Is this a legitimate threat or is this caused by the settings on the customer (contact) accounts that I’m mailing to? Customer Insights Journeys have a setting on the person profile (contact) that allows tracking of web activity. Currently this is on for all the contacts as I need to show that their responses to mail and website activity - with permission :wink: - can be tracked/recorded.
