### Email scanning limitations
We recommend using [always-on real-time protection](configure-real-time-protection-windows-defender-antivirus.md) to protect against email-based malware.
Always-on protection scans emails as they arrive and as they are manipulated, just like normal files in the operating system. This provides the strongest form of protection and is the recommended setting for scanning emails.
You can use this Group Policy to also enable scanning of older email files used by Outlook 2003 and older during on-demand and scheduled scans. Embedded objects within an email file (such as attachments and archived files) are also scanned. The following file format types can be scanned and remediated:
You can also use this Group Policy to enable scanning of older email files used by Outlook 2003 and older during on-demand and scheduled scans. Embedded objects within an email file (such as attachments and archived files) are also scanned. The following file format types can be scanned and remediated:
- DBX
- MBX
- MIME
PST files used by Outlook 2003 or older (where the archive type is set to non-unicode) can also be scanned, but Windows Defender cannot remediate threats detected inside PST files. This is another reason why we recommend using [always-on real-time protection](configure-real-time-protection-windows-defender-antivirus.md) to protect against email-based malware.
If Windows Defender Antivirus detects a threat inside an email, it will show you the following information to assist you in identifying the compromised email, so you can remediate the threat:
- Email subject
- Attachment name

## How it works
When a Windows Defender Antivirus client encounters a suspicious but undetected file, it queries our cloud protection backend. The cloud backend will apply heuristics, machine learning, and automated analysis of the file to determine the files as malicious or clean.
When antivirus encounters a suspicious but undetected file, it queries our cloud protection backend. The cloud backend applies heuristics, machine learning, and automated analysis of the file to determine whether the files are malicious or clean.
In Windows 10, version 1803, the Block at First Sight feature can now block non-portable executable files (such as JS, VBS, or macros) as well as executable files.
In Windows 10, version 1803, block at first sight can now block non-portable executable files (such as JS, VBS, or macros) as well as executable files.
The Block at First Sight feature only uses the cloud protection backend for executable files and non-portable executable files that are downloaded from the Internet, or originating from the Internet zone. A hash value of the .exe file is checked via the cloud backend to determine if this is a previously undetected file.
Block at first sight only uses the cloud protection backend for executable files and non-portable executable files that are downloaded from the Internet, or that originate from the Internet zone. A hash value of the .exe file is checked via the cloud backend to determine if this is a previously undetected file.
If the cloud backend is unable to make a determination, the file will be locked by Windows Defender AV while a copy is uploaded to the cloud. The cloud will perform additional analysis to reach a determination before it allows the file to run or blocks it in all future encounters, depending on whether the file is determined to be malicious or safe.
If the cloud backend is unable to make a determination, antivirus locks the file and uploads a copy to the cloud. The cloud performs additional analysis to reach a determination before it either allows the file to run or blocks it in all future encounters, depending on whether it determines the file to be malicious or safe.
In many cases this process can reduce the response time for new malware from hours to seconds.

If you use PowerShell, you can retrieve the list in two ways:
- Retrieve the status of all Windows Defender AV preferences. Each of the lists will be displayed on separate lines, but the items within each list will be combined into the same line.
- Retrieve the status of all antivirus preferences. Each of the lists will be displayed on separate lines, but the items within each list will be combined into the same line.
- Write the status of all preferences to a variable, and use that variable to only call the specific list you are interested in. Each use of `Add-MpPreference` is written to a new line.

To ensure antivirus cloud-delivered protection works properly, you need to configure your network to allow connections between your endpoints and certain Microsoft servers.
This topic lists the connections that must be allowed, such as by using firewall rules, and provides instructions for validating your connection. This will help ensure you receive the best protection from our cloud-delivered protection services.
See the Enterprise Mobility and Security blog post [Important changes to Microsoft Active Protection Services endpoint](https://blogs.technet.microsoft.com/enterprisemobility/2016/05/31/important-changes-to-microsoft-active-protection-service-maps-endpoint/) for some details about network connectivity.

## Configure standard notifications on endpoints
You can use Group Policy to:
- Display additional, customized text on endpoints when the user needs to perform an action
- Hide all notifications on endpoints
- Hide reboot notifications on endpoints
Hiding notifications can be useful in situations where you cannot hide the entire Windows Defender AV interface. See [Prevent users from seeing or interacting with the Windows Defender AV user interface](prevent-end-user-interaction-windows-defender-antivirus.md) for more information.
Hiding notifications can be useful in situations where you can't hide the entire antivirus interface. See [Prevent users from seeing or interacting with the antivirus user interface](prevent-end-user-interaction-windows-defender-antivirus.md) for more information.
> [!NOTE]
> Hiding notifications will only occur on endpoints to which the policy has been deployed. Notifications related to actions that must be taken (such as a reboot) will still appear on the [System Center Configuration Manager Endpoint Protection monitoring dashboard and reports](https://docs.microsoft.com/en-us/sccm/protect/deploy-use/monitor-endpoint-protection).
See the [Customize the Windows Defender Security Center app for your organization](/windows/security/threat-protection/windows-defender-security-center/windows-defender-security-center.md) topic for instructions to add custom contact information to the notifications that users see on their machines.

# Configure exclusions for files opened by processes
**Applies to:**
- Windows 10
- Windows Server 2016
**Audience**
- Enterprise security administrators
**Manageability available with**
- Microsoft Intune
- System Center Configuration Manager
- Group Policy
- PowerShell

You can exclude files that have been opened by specific processes from being scanned by Windows Defender AV.
You can exclude files that have been opened by specific processes from antivirus scans.
This topic describes how to configure exclusion lists for the following:
<a id="examples"></a>
Exclusion | Example
Exclusion | Example
---|---
Any file on the machine that is opened by any process with a specific file name | Specifying "test.exe" would exclude files opened by: <ul><li>c:\sample\test.exe</li><li>d:\internal\files\test.exe</li></ul>
Any file on the machine that is opened by any process under a specific folder | Specifying "c:\test\sample\\*" would exclude files opened by:<ul><li>c:\test\sample\test.exe</li><li>c:\test\sample\test2.exe</li><li>c:\test\sample\utility.exe</li></ul>
Any file on the machine that is opened by a specific process in a specific folder | Specifying "c:\test\process.exe" would exclude files only opened by c:\test\process.exe
When you add a process to the process exclusion list, Windows Defender AV will not scan files opened by that process, no matter where the files are located. The process itself, however, will be scanned unless it has also been added to the [file exclusion list](configure-extension-file-exclusions-windows-defender-antivirus.md).

Windows Defender Antivirus uses several methods to provide threat protection:
Antivirus uses several methods to provide threat protection:
- Cloud-delivered protection for near-instant detection and blocking of new and emerging threats
- Always-on scanning, using file and process behavior monitoring and other heuristics (also known as "real-time protection")
- Dedicated protection updates based on machine-learning, human and automated big-data analysis, and in-depth threat resistance research
You can configure how Windows Defender AV uses these methods with Group Policy, System Center Configuration Manage, PowerShell cmdlets, and Windows Management Instrumentation (WMI).

Always-on protection consists of real-time protection, behavior monitoring, and heuristics to identify malware based on known suspicious and malicious activities.
Always-on protection consists of real-time protection, behavior monitoring, and heuristics to identify malware based on known suspicious and malicious activities.
These activities include events such as processes making unusual changes to existing files, modifying or creating automatic startup registry keys and startup locations (also known as auto-start extensibility points, or ASEPs), and other changes to the file system or file structure.
## Configure and enable always-on protection
You can configure how always-on protection works with the Group Policy settings described in this section.
To configure these settings:
1. On your Group Policy management machine, open the [Group Policy Management Console](https://technet.microsoft.com/library/cc731212.aspx), right-click the Group Policy Object you want to configure and click **Edit**.
3. In the **Group Policy Management Editor** go to **Computer configuration** and click **Administrative templates**.
5. Expand the tree to **Windows components > Windows Defender Antivirus** and then the **Location** specified in the table below.
6. Double-click the policy **Setting** as specified in the table below, and set the option to your desired configuration. Click **OK**, and repeat for any other settings.

## Create and deploy the base image
## Create and deploy the base image
The main steps in this section include:
1. Create your standard base image according to your requirements
2. Apply Windows Defender AV protection updates to your base image
3. Seal or “lock” the image to create a “known-good” image
4. Deploy your image to your VMs
1. Create your standard base image according to your requirements
2. Apply Windows Defender AV protection updates to your base image
3. Seal or “lock” the image to create a “known-good” image
4. Deploy your image to your VMs
### Create the base image
First, you should create your base image according to your business needs, applying or installing the relevant line of business (LOB) apps and settings as you normally would. Typically, this would involve creating a VHD or customized .iso, depending on how you will deploy the image to your VMs.
### Apply protection updates to the base image
After creating the image, you should ensure it is fully updated. See [Configure Windows Defender in Windows 10]( https://technet.microsoft.com/en-us/itpro/windows/keep-secure/configure-windows-defender-in-windows-10) for instructions on how to update Windows Defender AV protection via WSUS, Microsoft Update, the MMPC site, or UNC file shares. You should ensure that your initial base image is also fully patched with Microsoft and Windows updates and patches.

You should ensure that your initial base image is also fully patched with Microsoft and Windows updates and patches.
### Seal the base image
When the base image is fully updated, you should run a quick scan on the image.
After running a scan and buliding the cache, remove the machine GUID that uniquely identifies the device in telemetry for both Windows Defender Antivirus and the Microsoft Security Removal Tool. This key is located here:
When the base image is fully updated, you should run a quick scan on the image.
After running a scan and buliding the cache, remove the machine GUID that uniquely identifies the device in telemetry for both antivirus and the Microsoft Security Removal Tool. This key is located here:
'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\RemovalTools\MRT'
Remove the string found in the 'GUID' value
This “sealing” or “locking” of the image helps Windows Defender AV build a cache of known-good files and avoid scanning them again on your VMs. In turn, this can help ensure performance on the VM is not impacted.
This “sealing” or “locking” of the image helps antivirus build a cache of known-good files and avoid scanning them again on your VMs. In turn, this can help ensure performance on the VM is not impacted.
You can run a quick scan [from the command line](command-line-arguments-windows-defender-antivirus.md) or via [System Center Configuration Manager](run-scan-windows-defender-antivirus.md).
>[!NOTE]
>[!NOTE]
><b>Quick scan versus full scan</b>
>Quick scan looks at all the locations where there could be malware registered to start with the system, such as registry keys and known Windows startup folders. Combined with our always on real-time protection capability - which reviews files when they are opened and closed, and whenever a user navigates to a folder – quick scan helps provide strong coverage both for malware that starts with the system and kernel-level malware.
>Therefore, when considering performance – especially for creating a new or updated image in preparation for deployment – it makes sense to use a quick scan only.
>Therefore, when considering performance – especially for creating a new or updated image in preparation for deployment – it makes sense to use a quick scan only.

## Manage your VMs and base image
How you manage your VDI will affect the performance impact of Windows Defender AV on your VMs and infrastructure.
Because Windows Defender AV downloads protection updates every day, or [based on your protection update settings](manage-protection-updates-windows-defender-antivirus.md), network bandwidth can be a problem if multiple VMs attempt to download updates at the same time.
Because antivirus downloads protection updates every day, or [based on your protection update settings](manage-protection-updates-windows-defender-antivirus.md), network bandwidth can be a problem if multiple VMs attempt to download updates at the same time.
Following the guidelines in this means the VMs will only need to download “delta” updates, which are the differences between an existing definition set and the next one. Delta updates are typically much smaller (a few kilobytes) than a full definition download (which can average around 150 mb).
### Manage updates for persistent VDIs
If you are using a persistent VDI, you should update the base image monthly, and set up protection updates to be delivered daily via a file share, as follows:
1. Create a dedicated file share location on your network that can be accessed by your VMs and your VM host (or other, persistent machine, such as a dedicated admin console that you use to manage your VMs).
2. Set up a scheduled task on your VM host to automatically download updates from the MMPC website or Microsoft Update and save them to the file share (the [SignatureDownloadCustomTask PowerShell script](https://www.powershellgallery.com/packages/SignatureDownloadCustomTask/1.4/DisplayScript) can help with this).
3. [Configure the VMs to pull protection updates from the file share](manage-protection-updates-windows-defender-antivirus.md).
4. Disable or delay automatic Microsoft updates on your VMs. See [Update Windows 10 in the enterprise](https://technet.microsoft.com/en-us/itpro/windows/manage/waas-update-windows-10) for information on managing operating system updates with WSUS, SCCM, and others.
5. On or just after each Patch Tuesday (the second Tuesday of each month), [update your base image with the latest protection updates from the MMPC website, WSUS, or Microsoft Update](manage-protection-updates-windows-defender-antivirus.md) Also apply all other Windows patches and fixes that were delivered on the Patch Tuesday. You can automate this by following the instructions in [Orchestrated offline VM Patching using Service Management Automation](https://blogs.technet.microsoft.com/privatecloud/2013/12/06/orchestrated-offline-vm-patching-using-service-management-automation/).
5. [Run a quick scan](run-scan-windows-defender-antivirus.md) on your base image before deploying it to your VMs.
A benefit to aligning your image update to the monthly Microsoft Update is that you ensure your VMs will have the latest Windows security patches and other important Microsoft updates without each VM needing to individually download them.

A benefit to aligning your image update to the monthly Microsoft Update is that you ensure your VMs will have the latest Windows security patches and other important Microsoft updates without each VM needing to individually download them.
### Manage updates for non-persistent VDIs
If you are using a non-persistent VDI, you can update the base image daily (or nightly) and directly apply the latest updates to the image.
An example:
1. Every night or other time when you can safely take your VMs offline, update your base image with the latest [protection updates from the MMPC website, WSUS, or Microsoft Update](manage-protection-updates-windows-defender-antivirus.md).
2. [Run a quick scan](run-scan-windows-defender-antivirus.md) on your base image before deploying it to your VMs.
## Configure endpoints for optimal performance
There are a number of settings that can help ensure optimal performance on your VMs and VDI without affecting the level of protection, including:
- [Randomize scheduled scans](#randomize-scheduled-scans)
- [Use quick scans](#use-quick-scans)
- [Prevent notifications](#prevent-notifications)
- [Disable scans from occurring after every update](#disable-scans-after-an-update)

- [Randomize scheduled scans](#randomize-scheduled-scans)
- [Use quick scans](#use-quick-scans)
- [Prevent notifications](#prevent-notifications)
- [Disable scans from occurring after every update](#disable-scans-after-an-update)
- [Scan out-of-date machines or machines that have been offline for a while](#scan-vms-that-have-been-offline)
These settings can be configured as part of creating your base image, or as a day-to-day management function of your VDI infrastructure or network.
### Randomize scheduled scans
Windows Defender AV supports the randomization of scheduled scans and signature updates. This can be extremely helpful in reducing boot storms (especially when used in conjunction with [Disable scans from occurring after every update](#disable-scans-after-an-update) and [Scan out-of-date machines or machines that have been offline for a while](#scan-vms-that-have-been-offline).

The Potentially Unwanted Application (PUA) protection feature in Windows Defender Antivirus can identify and block PUAs from downloading and installing on endpoints in your network.
The potentially unwanted application (PUA) antivirus protection feature can identify and block PUAs from downloading and installing on endpoints in your network.
These applications are not considered viruses, malware, or other types of threats, but might perform actions on endpoints that adversely affect their performance or use. PUA can also refer to applications that are considered to have a poor reputation.
Typical PUA behavior includes:
- Various types of software bundling
- Ad-injection into web browsers
- Ad injection into web browsers
- Driver and registry optimizers that detect issues, request payment to fix the errors, but remain on the endpoint and make no changes or optimizations (also known as "rogue antivirus" programs)
These applications can increase the risk of your network being infected with malware, cause malware infections to be harder to identify, and can waste IT resources in cleaning up the applications.

>You can also visit the Windows Defender Testground website at [demo.wd.microsoft.com](https://demo.wd.microsoft.com?ocid=cx-wddocs-testground) to confirm the feature is working and see how it works.

## How it works
PUAs are blocked when a user attempts to download or install the detected file, and if the file meets one of the following conditions:
- The file is being scanned from the browser
- The file is in a folder with "**downloads**" in the path
- The file is in a folder with "**temp**" in the path
- The file is on the user's Desktop
- The file is on the user's desktop
- The file does not meet one of these conditions and is not under *%programfiles%*, *%appdata%*, or *%windows%*
The file is placed in the quarantine section so it won't run.
The file is placed in the quarantine section so it won't run.
When a PUA is detected on an endpoint, the endpoint will present a notification to the user ([unless notifications have been disabled](configure-notifications-windows-defender-antivirus.md)) in the same format as normal threat detections (prefaced with "PUA:").
They will also appear in the usual [quarantine list in the Windows Defender Security Center app](windows-defender-security-center-antivirus.md#detection-history).

PUA events are reported in the Windows Event Viewer and not in System Center Configuration Manager or Intune.

Limited periodic scanning is a special type of threat detection and remediation that can be enabled when you have installed another antivirus product on a Windows 10 device.
It can only be enabled in certain situations. See the [Windows Defender Antivirus compatibility](windows-defender-antivirus-compatibility.md) topic for more information on when limited periodic scanning can be enabled, and how Windows Defender Antivirus works with other AV products.

**Microsoft does not recommend using this feature in enterprise environments. This is a feature primarily intended for consumers.** This feature only uses a very limited subset of the capabilities of Windows Defender Antivirus to detect malware, and will not be able to detect most malware and potentially unwanted software. Also, management and reporting capabilities will be limited. Microsoft recommends enterprises choose their primary antivirus solution and use it exclusively.

Windows Defender AV lets you define how long an endpoint can avoid an update or how many scans it can miss before it is required to update and scan itself. This is especially useful in environments where devices are not often connected to a corporate or external network, or devices that are not used on a daily basis.
Next generation protection lets you define how long an endpoint can avoid an update or how many scans it can miss before it is required to update and scan itself. This is especially useful in environments where devices are not often connected to a corporate or external network, or devices that are not used on a daily basis.
For example, an employee that uses a particular PC is on break for three days and does not log on to their PC during that time.
When the user returns to work and logs on to their PC, Windows Defender AV will immediately check and download the latest protection updates, and run a scan.
When the user returns to work and logs on to their PC, antivirus will immediately check and download the latest protection updates, and run a scan.
## Set up catch-up protection updates for endpoints that haven't updated for a while
If Windows Defender AV did not download protection updates for a specified period, you can set it up to automatically check and download the latest update at the next log on. This is useful if you have [globally disabled automatic update downloads on startup](manage-event-based-updates-windows-defender-antivirus.md).

This is useful if you have [globally disabled automatic update downloads on startup](manage-event-based-updates-windows-defender-antivirus.md).
**Use Configuration Manager to configure catch-up protection updates:**
1. On your System Center Configuration Manager console, open the antimalware policy you want to change (click **Assets and Compliance** in the navigation pane on the left, then expand the tree to **Overview** > **Endpoint Protection** > **Antimalware Policies**)
2. Go to the **Definition updates** section and configure the following settings:
1. Set **Force a definition update if the client computer is offline for more than two consecutive scheduled updates** to **Yes**.
2. For the **If Configuration Manager is used as a source for definition updates...**, specify the hours before which the protection updates delivered by Configuration Manager should be considered out-of-date. This will cause the next update location to be used, based on the defined [fallback source order](manage-protection-updates-windows-defender-antivirus.md#fallback-order).

## Protection updates
Windows Defender AV uses both [cloud-delivered protection](utilize-microsoft-cloud-protection-windows-defender-antivirus.md) (also called the Microsoft Advanced Protection Service or MAPS) and periodically downloaded protection updates to provide protection. These protection updates are also known as "definitions" or "signature updates".
Antivirus uses both [cloud-delivered protection](utilize-microsoft-cloud-protection-windows-defender-antivirus.md) (also called the Microsoft Advanced Protection Service or MAPS) and periodically downloaded protection updates to provide protection. These protection updates are also known as "definitions" or "signature updates".
The cloud-delivered protection is always on and requires an active connection to the Internet to function, while the protection updates generally occur once a day (although this can be configured). See the [Utilize Microsoft cloud-provided protection in Windows Defender Antivirus](utilize-microsoft-cloud-protection-windows-defender-antivirus.md) topic for more details about enabling and configuring cloud-provided protection.
## Product updates
Windows Defender AV requires [monthly updates](https://support.microsoft.com/en-us/help/4052623/update-for-windows-defender-antimalware-platform) (known as "engine updates" and "platform updates"), and will receive major feature updates alongside Windows 10 releases.

You can manage the distribution of updates through Windows Server Update Service (WSUS), with [System Center Configuration Manager](https://docs.microsoft.com/en-us/sccm/sum/understand/software-updates-introduction), or in the normal manner that you deploy Microsoft and Windows updates to endpoints in your network.

Quick scan looks at all the locations where there could be malware registered to start with the system, such as registry keys and known Windows startup folders.
Combined with [always-on real-time protection capability](configure-real-time-protection-windows-defender-antivirus.md) - which reviews files when they are opened and closed, and whenever a user navigates to a folder - a quick scan helps provide strong coverage both for malware that starts with the system and kernel-level malware.
Combined with [always-on real-time protection capability](configure-real-time-protection-windows-defender-antivirus.md)--which reviews files when they are opened and closed, and whenever a user navigates to a folder--a quick scan helps provide strong coverage both for malware that starts with the system and kernel-level malware.
In most instances, this means a quick scan is adequate to find malware that wasn't picked up by real-time protection.
A full scan can be useful on endpoints that have encountered a malware threat to identify if there are any inactive components that require a more thorough clean-up, and can be ideal when running on-demand scans.

# Use next-gen technologies in Windows Defender Antivirus through cloud-delivered protection
**Applies to:**
- Windows 10, version 1703 and later
**Audience**
- Enterprise security administrators
Microsoft next-gen technologies in Windows Defender Antivirus provide near-instant, automated protection against new and emerging threats. To dynamically identify new threats, these technologies work with large sets of interconnected data in the Microsoft Intelligent Security Graph and powerful artificial intelligence (AI) systems driven by advanced machine learning models.
To take advantage of the power and speed of these next-gen technologies, Windows Defender Antivirus works seamlessly with Microsoft cloud services. These cloud protection services, also referred to as Microsoft Advanced Protection Service (MAPS), enhances standard real-time protection, providing arguably the best antivirus defense.

# Windows Defender Antivirus compatibility
**Applies to:**

**Audience**
- Enterprise security administrators
Windows Defender Antivirus is automatically enabled and installed on endpoints and devices that are running Windows 10.
However, on endpoints and devices that are protected with a non-Microsoft antivirus or antimalware app, Windows Defender AV will automatically disable itself. You can then choose to enable an optional, limited protection feature, called [limited periodic scanning](limited-periodic-scanning-windows-defender-antivirus.md).
