Resolve

Restart Windows Defender

The scanning engine must be available when Windows Defender starts. Close Windows Defender and then open it again. If the scanning engine is still not available, restart the computer.

Verify

Windows Defender uses the scanning engine to run Windows Defender scans. To verify that the scanning engine updated successfully and is working correctly, you should run a Windows Defender quick scan.

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 scanning engine updated successfully and is working correctly:

  1. Click Start, point to All Programs, and then click Windows Defender.
  2. Click the down arrow next to Scan, and then click Quick Scan.
  3. If the quick scan completes successfully, the scanning engine was updated successfully and is working correctly.
