Microsoft Windows Defender: Main Window
The airy main window of Microsoft Windows Defender displays current security status (in detail, if necessary) and offers easy access to on-demand scanning.
Microsoft Windows Defender: Malware Detected
When Windows Defender's real-time component detects malware, it displays a simple, transient notification at the display's top right corner.
Microsoft Windows Defender: Clean PC
Sometimes the real-time component can't completely neutralize found malware. In that case, you may get a warning that you need to reboot for complete cleanup.
Microsoft Windows Defender: Detected Items
To see what the real-time malware protection component did, you'll need to dig into the History tab. The tab displays details for whatever item you've selected, with a link to get more information online.
Microsoft Windows Defender: Advanced Settings
Most users won't need to change any of this tool's settings; their defaults are just fine.
Microsoft Windows Defender: Scan Complete
When Windows Defender finishes an on-demand scan, it waits for your permission to clean up the found malware. You can click to view details first, or just go straight to cleaning up the mess.
Microsoft Windows Defender: Scan Details
If you do click for details on what the scan found, you'll get a list of detected items by name, not filename. For each item it reports the alert level, status, and recommended action.
