# What to do with false positives/negatives in Windows Defender Antivirus
**Applies to:**
- [Microsoft Defender Advanced Threat Protection (Microsoft Defender ATP)](https://go.microsoft.com/fwlink/p/?linkid=2069559)
Windows Defender Antivirus is designed to keep your PC safe with built-in, trusted antivirus protection. With Windows 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.
But 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 things. 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); or
- [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) by Windows Defender Antivirus.
## 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 Windows Defender Antivirus (and Microsoft Defender Advanced Threat Protection) 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 Windows 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 Windows Defender Antivirus. |
|**Folder** |Location <br/>Example: `c:\test\sample` |All items in the specified folder are skipped by Windows Defender Antivirus. |
|**File type** |File extension <br/>Example: `.test` |All files with the specified extension anywhere on your device are skipped by Windows 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 Windows Defender Antivirus. |

You can exclude certain files, folders, processes, and process-opened files from Windows Defender Antivirus scans.
The exclusions apply to [scheduled scans](scheduled-catch-up-scans-windows-defender-antivirus.md), [on-demand scans](run-scan-windows-defender-antivirus.md), and [always-on real-time protection and monitoring](configure-real-time-protection-windows-defender-antivirus.md). Exclusions for process-opened files only apply to real-time protection.
Exclusions can be useful to avoid incorrect detections on files or software that are unique or customized to your organization.
Windows Server 2016 also features automatic exclusions that are defined by the server roles you enable. See the [Windows Defender Antivirus exclusions on Windows Server 2016](configure-server-exclusions-windows-defender-antivirus.md) topic for more information and a list of the automatic exclusions.
