We recommend using Microsoft Intune to manage Microsoft Defender Antivirus settings for your organization. However, you can use Group Policy to configure and manage some settings for Microsoft Defender Antivirus.
Važno
If tamper protection is enabled in your organization, any changes made to tamper-protected settings are ignored. In addition, you cannot turn off tamper protection by using Group Policy.
If you must make changes to a device and those changes are blocked by tamper protection, we recommend using troubleshooting mode to temporarily disable tamper protection on the device. Note that after troubleshooting mode ends, any changes made to tamper-protected settings are reverted to their configured state.
In general, you can use the following procedure to configure or change some settings for Microsoft Defender Antivirus.
On your Group Policy management machine, open the Group Policy Management Console, right-click the Group Policy Object (GPO) you want to configure and select Edit.
Using the Group Policy Management Editor go to Computer configuration.
Select Administrative templates.
Expand the tree to Windows components > Microsoft Defender Antivirus.
Expand the section (referred to as Location in the table in this article) that contains the setting you want to configure, double-click the setting to open it, and make configuration changes.
The following table lists commonly used Group Policy settings that are available in Windows 10.

For the most current settings, get the latest ADMX files in your central store to access the correct policy options. See How to create and manage the Central Store for Group Policy Administrative Templates in Windows and download the latest files.

Instead of using "Run full scan on mapped network drives", if you have a Network-Attached Storage (NAS) or Storage Area Network (SAN), you can use Internet Content Adaption Protocol (ICAP) scanning with the Microsoft Defender Antivirus engine. For more information, see Tech Community Blog: MetaDefender ICAP with Windows Defender Antivirus: World-class security for hybrid environments.

Performance tip Due to a variety of factors (examples listed below) Microsoft Defender Antivirus, like other antivirus software, can cause performance issues on endpoint devices. In some cases, you might need to tune the performance of Microsoft Defender Antivirus to alleviate those performance issues. Microsoft's Performance analyzer is a PowerShell command-line tool that helps determine which files, file paths, processes, and file extensions might be causing performance issues; some examples are:
You can use the information gathered using Performance analyzer to better assess performance issues and apply remediation actions. See: Performance analyzer for Microsoft Defender Antivirus.
