Windows Defender is an anti-malware system that is used to identify malware on a Windows system. With Windows Defender enabled, it will detect, remove, or quarantine malware on your computer. However, Windows Defender will not scan USB flash drives for viruses automatically when you plug in a USB drive.
Why does Windows set up like this?
Why Windows Defender Does Not Scan USB Flash Drives for Viruses Automatically
In previous Windows versions, Windows Defender automatically scans USB flash drives when they are plugged in. However, this feature is disabled in recent Windows versions. Microsoft did not make a clear statement on this to explain the reason.
The biggest reason for Windows to cancel this setting may be that Windows Defender automatically scans USBs may cause data loss. If you want to enable Windows Defender to scan USB flash drives for viruses automatically, you can try the following ways.
How to Make Windows Defender Scan USB Automatically
Way 1. Using Registry Editor
To make Windows Defender scan USB automatically, you can edit the Windows registry.
Note: Before making any changes to the registry, you had better back up the registry in case of any accidents because any wrong operations to the registry could lead to computer failure.
Step 1. Press Windows + R key combinations to open Run.
Step 2. Type regedit in the input box and press Enter. Then click Yes in the pop-up UAC window.
Step 3. In the top address bar, copy and paste the following location, then press Enter:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender
Step 4. In the left panel, right-click Windows Defender to select New > Key.
Step 5. Change the created key’s name to Scan.
Step 6. Select the new key – Scan. Then in the right panel, right-click any blank space to choose New > DWORD (32-bit) Value. After that, rename the new DWORD to DisableRemovableDriveScanning.
Step 7. Double-click the created DWORD and set its value to 0. After that, click OK to save your changes.
Now Windows Defender is enabled to scan your USB drives automatically.
Way 2. Using Group Policy Editor
In addition to Registry Editor, you can use Group Policy Editor to make Windows Defender scan USB automatically. Group Policy Editor is a Windows administration tool that allows you to configure important Windows settings.
Step 1. Press Windows + R key combinations. Then type gpedit.msc in the input box and press Enter.
Step 2. In the left panel of the new window, navigate to Computer Configuration > Administrative Templates > Windows Components > Windows Defender Antivirus.
Step 3. In the right panel, double-click the folder of Scan. Then find and double-click Scan removable drives. This feature is not configured by default.
Step 4. In the new scan removable drives window, select Enabled and click Apply.
Now the Windows Defender is configured to scan USB flash drives for viruses.
How to stop Windows Defender from scanning external drives? You just need to restore “Scan removable drives” to Not Configured or Disabled.
