# What to do with false positives/negatives in Microsoft Defender Antivirus
|
||||
|
||||
[!INCLUDE [Microsoft 365 Defender rebranding](../../includes/microsoft-defender.md)]
|
||||
|
||||
|
||||
**Applies to:**
|
||||
|
||||
- [Microsoft Defender for Endpoint](https://go.microsoft.com/fwlink/p/?linkid=2146631)
|
||||
|
||||
Microsoft Defender Antivirus is designed to keep your PC safe with built-in, trusted antivirus protection. With Microsoft Defender Antivirus, you get comprehensive, ongoing, and real-time protection against software threats like viruses, malware, and spyware across email, apps, the cloud, and the web.
|
||||
|
||||
What if something gets detected wrongly as malware, or something is missed? We call these false positives and false negatives. Fortunately, there are some steps you can take to deal with these issues. You can:
|
||||
- [Submit a file to Microsoft for analysis](#submit-a-file-to-microsoft-for-analysis)
|
||||
- [Create an "Allow" indicator to prevent a false positive from recurring](#create-an-allow-indicator-to-prevent-a-false-positive-from-recurring)
|
||||
- [Define an exclusion on an individual Windows device to prevent an item from being scanned](#define-an-exclusion-on-an-individual-windows-device-to-prevent-an-item-from-being-scanned)
|
||||
|
||||
## Submit a file to Microsoft for analysis
|
||||
|
||||
1. Review the [submission guidelines](../intelligence/submission-guide.md).
|
||||
2. [Submit your file or sample](https://www.microsoft.com/wdsi/filesubmission).
|
||||
|
||||
> [!TIP]
|
||||
> We recommend signing in at the submission portal so you can track the results of your submissions.
|
||||
|
||||
## Create an "Allow" indicator to prevent a false positive from recurring
|
||||
|
||||
If a file, IP address, URL, or domain is treated as malware on a device, even though it's safe, you can create an "Allow" indicator. This indicator tells Microsoft Defender Antivirus (and Microsoft Defender for Endpoint) that the item is safe.
|
||||
|
||||
To set up your "Allow" indicator, follow the guidance in [Manage indicators](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/manage-indicators).
|
||||
|
||||
## Define an exclusion on an individual Windows device to prevent an item from being scanned
|
||||
|
||||
When you define an exclusion for Microsoft Defender Antivirus, you configure your antivirus to skip that item.
|
||||
|
||||
1. On your Windows 10 device, open the Windows Security app.
|
||||
2. Select **Virus & threat protection** > **Virus & threat protection settings**.
|
||||
3. Under **Exclusions**, select **Add or remove exclusions**.
|
||||
4. Select **+ Add an exclusion**, and specify its type (**File**, **Folder**, **File type**, or **Process**).
|
||||
|
||||
The following table summarizes exclusion types, how they're defined, and what happens when they're in effect.
|
||||
|
||||
|Exclusion type |Defined by |What happens |
|
||||
|---------|---------|---------|
|
||||
|**File** |Location <br/>Example: `c:\sample\sample.test` |The specified file is skipped by Microsoft Defender Antivirus. |
|
||||
|**Folder** |Location <br/>Example: `c:\test\sample` |All items in the specified folder are skipped by Microsoft Defender Antivirus. |
|
||||
|**File type** |File extension <br/>Example: `.test` |All files with the specified extension anywhere on your device are skipped by Microsoft Defender Antivirus. |
|
||||
|**Process** |Executable file path <br>Example: `c:\test\process.exe` |The specified process and any files that are opened by that process are skipped by Microsoft Defender Antivirus. |
|
||||
|
||||

In endpoint protection, a false positive is an entity, such as a file or a process, that was detected and identified as malicious, even though the entity isn't actually a threat. A false negative is an entity that was not detected as a threat, even though it actually is malicious. If you’re using [Microsoft Defender for Endpoint](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/microsoft-defender-advanced-threat-protection), and you're seeing false positives/negatives in your [Microsoft Defender Security Center](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/use), your security operations can take steps to address false positives or false negatives.

In general, you should not need to define exclusions for Microsoft Defender Antivirus. Make sure that you define exclusions sparingly, and that you only include the files, folders, processes, and process-opened files that are resulting in false positives. In addition, make sure to review your defined exclusions regularly. We recommend using Microsoft Endpoint Manager to define or edit your antivirus exclusions; however, you can use other methods, such as Group Policy as well.

#### Indicators for files
|
||||
|
||||
When you [create an "allow" indicator for a file, such as an executable](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/indicator-file), it helps prevent files that your organization is using from being blocked. Files can include portable executable (PE) files, such as `.exe` and `.dll` files.
|
||||
|
||||
Before you create indicators for files, make sure the following requirements are met:
|
||||
- Microsoft Defender Antivirus is configured with cloud-based protection enabled (see [Manage cloud-based protection](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-antivirus/deploy-manage-report-microsoft-defender-antivirus))
|
||||
- Antimalware client version is 4.18.1901.x or later
|
||||
- Devices are running Windows 10, version 1703 or later; Windows Server 2016; or Windows Server 2019
|
||||
- The [Block or allow feature is turned on](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/advanced-features)
|
||||
|
||||
#### Indicators for IP addresses, URLs, or domains
|
||||
|
||||
When you [create an "allow" indicator for an IP address, URL, or domain](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/indicator-ip-domain), it helps prevent the sites or IP addresses your organization uses from being blocked.
|
||||
|
||||
Before you create indicators for IP addresses, URLs, or domains, make sure the following requirements are met:
|
||||
- Network protection in Defender for Endpoint is enabled in block mode (see [Enable network protection](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/enable-network-protection))
|
||||
- Antimalware client version is 4.18.1906.x or later
|
||||
- Devices are running Windows 10, version 1709, or later
|
||||
|
||||
Custom network indicators are turned on in the Microsoft Defender Security Center (see [Advanced features](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/advanced-features))
|
||||
|
||||
#### Indicators for application certificates
|
||||
|
||||
When you [create an "allow" indicator for an application certificate](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/indicator-certificates), it helps prevent applications, such as internally developed applications, that your organization uses from being blocked. `.CER` or `.PEM` file extensions are supported.
|
||||
|
||||
Before you create indicators for application certificates, make sure the following requirements are met:
|
||||
- Microsoft Defender Antivirus is configured with cloud-based protection enabled (see [Manage cloud-based protection](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-antivirus/deploy-manage-report-microsoft-defender-antivirus))
|
||||
- Antimalware client version is 4.18.1901.x or later
|
||||
- Devices are running Windows 10, version 1703 or later; Windows Server 2016; or Windows Server 2019
|
||||
- Virus and threat protection definitions are up to date
|
||||
|
||||
> [!TIP]
|
||||
> When you create indicators, you can define them one by one or import multiple items at once. Keep in mind there's a limit of 15,000 indicators you can have in a single tenant. And, you might need to gather certain details first, such as file hash information. Make sure to review the prerequisites before you [create indicators](manage-indicators.md).

Potentially unwanted applications (PUA) are a category of software that can cause devices to run slowly, display unexpected ads, or install other software that might be unexpected or unwanted. Examples of PUA include advertising software, bundling software, and evasion software that behaves differently with security products. Although PUA is not considered malware, some kinds of software are PUA based on their behavior and reputation.
|
||||
|
||||
Depending on the apps your organization is using, you might be getting false positives as a result of your PUA protection settings. If this is happening, consider running PUA protection in audit mode for a while, or apply PUA protection to a subset of devices in your organization. PUA protection can be configured for the Microsoft Edge browser and for Microsoft Defender Antivirus.

||||
We recommend using Microsoft Endpoint Manager to edit or set PUA protection settings.

[Automated investigation and remediation](automated-investigations.md) (AIR) capabilities are designed to examine alerts and take immediate action to resolve breaches. As alerts are triggered, and an automated investigation runs, a verdict is generated for each piece of evidence investigated. Verdicts can be *Malicious*, *Suspicious*, or *No threats found*.
|
||||
|
||||
Depending on the [level of automation](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/automation-levels) set for your organization, as well as other security settings, remediation actions are taken on artifacts deemed Malicious or Suspicious. Remediation actions can occur automatically, or only upon approval by your security operations team.
