Investigating

We are aware that Microsoft Defender is incorrectly flagging the MSI installers as false positives, which may temporarily prevent new agents from being installed or downloaded.

Our team is already working directly with Microsoft to get this resolved as a top priority. We'll be sure to provide another update as soon as a fix is available.

We appreciate your patience and apologize for any inconvenience this has caused.
