PowerShell process might hang randomly with ENS Threat Prevention

Technical Articles ID: KB94807
Last Modified: 9/15/2021

Environment

McAfee Endpoint Security (ENS) Threat Prevention 10.7.0 November 2020 Update and later

Problem

Users might see the PowerShell process hang randomly on a system. To recover PowerShell, you might need to relaunch the PowerShell process. The issue doesn’t occur if ENS isn’t installed on the system. During Windows deployment/upgrade using System Center Configuration Manager (SCCM) or other methods, after ENS is installed, installation of other products might hang due to the PowerShell hang. This issue occurs when all products are combined into a single task.

Cause

This issue occurs due to a loader lock deadlock that ENS loglib.dll causes when performing activity from the main DLL.

Solution

This issue is resolved in ENS 10.7.0 September 2021 Update.

Our product software, upgrades, maintenance releases, and documentation are available on the Product Downloads site.

NOTE: You need a valid Grant Number for access. See KB56057 - How to download Enterprise product updates and documentation for more information about the Product Downloads site, and alternate locations for some products.

Workaround

Disabling Antimalware Scan Interface (AMSI) might resolve the issue in certain cases.
