ERR_MP_BAD_INPUT_DATA (0x8050800C)

This error code indicates that an internal error has occurred. You should restart your computer.

  2. Click the down arrow next to Scan, and then click Full Scan.
  3. Check that the full scan completed successfully.

ERR_MP_MANUAL_STEPS_REQUIRED (0x80508025)

The Windows Defender History will tell you the name of the spyware or other potentially unwanted software that was not fully removed. For more information about additional steps, see the Microsoft Malware Protection Center (https://go.microsoft.com/fwlink/?LinkId=99353), and search the encyclopedia for the name of the spyware or other potentially unwanted software.

ERR_MP_NO_MEMORY (0x80508007)

This error code indicates that your computer is low on resources. You should free up some memory on your computer.

To perform this procedure, you must be a member of the Administrators group, or you must have been delegated the appropriate authority.

To free up memory on your computer:

  1. Right-click the taskbar, and then click Task Manager.

This error code indicates that a file or location included in the scan does not exist. This can happen if you try to quarantine spyware or other potentially unwanted software that no longer exists on the computer.

To perform this procedure, you must be a member of the Users group, or you must have been delegated the appropriate authority.

Low, Medium, and High threats will be detected but not removed unless your copy of Windows is genuine.

To perform this procedure, you must be a member of the Users group, or you must have been delegated the appropriate authority.

To ensure that your computer is genuine:

  1. Click Start, and then click Internet.
  2. Type https://go.microsoft.com/fwlink/?LinkId=99354 in the address bar, and then press ENTER.
  3. Click Validate Windows.

ERR_MP_REMOVE_NOT_SUPPORTED (0x80508026)

During a scan, Windows Defender detected spyware or other potentially unwanted software contained within a file archive, such as a .zip file. You should identity whether or not the file is spyware or other potentially unwanted software and remove it from the archive manually.

Verify

When Windows Defender takes an action on spyware or other potentially unwanted software, an entry is created in the Windows Defender History. To verify that the spyware or other potentially unwanted software was successfully removed from your computer, you should verify that an entry was created in the Windows Defender History and that the appropriate action was taken.

To perform this procedure, you must be a member of the Users group, or you must have been delegated the appropriate authority.

To verify that the spyware or other potentially unwanted software was successfully removed:

  1. Click Start, point to All Programs, and then click Windows Defender.
  2. Click History.
  3. Under Programs and Actions, verify that the Action Taken column says Remove.
  4. Verify that the Status column says Succeeded.
  5. Close Windows Defender.

Note: If you clicked Ignore or Always Allow for the action in the Windows Defender alert, the Action Taken column will display either Ignore or Always Allow.
