    Information Windows Defender helps protect your PC against malware (malicious software) like viruses, spyware, and other potentially unwanted software. Malware can infect your PC without your knowledge: it might install itself from an email message, when you connect to the Internet, or when you install certain apps using a USB flash drive, CD, DVD, or other removable media. Some malware can also be programmed to run at unexpected times, not only when it's installed.

    You can set a group policy that allows you to manage whether or not Windows Defender scans for malicious software and unwanted software in the contents of mapped network drives when running a full scan.

    Mapped network drives can always be scanned during a quick scan and custom scan.

    This tutorial will show you how to enable or disable Windows Defender to include mapped network drives during a full scan in Windows 10.

    You must be signed in as an administrator to enable or disable scan mapped network drives during a full scan.

    Windows defender custom scan does not scan external drives

    I have Defender Windows 10. I tried using custom scan to select and scan external drives. The screen listing the drives comes up, but the "OK" button remains grayed out so unable to scan any of the drives listed. Any suggestions would be appreciated.

    Windows 10 Anniversary Update Issues

    Problems with W10 Anniv auto update:

    Mom's: (x58 Xeon 5677) Windows Defender was not turned back on automatically (it was "on" in the 1511 edition) and she had a Trojan. Full system scan to eradicate.
    Her Epson printer was knocked off, had to uninstall by Device Manager pull USB cable and reconnect cable. W10 did the rest.

    Step-mom's: (HP pre built) Windows Defender not turned back on by default. Her USB Seagate Expansion Drive 2Tb was offline so all backup routines were halted. Had to rerun backup plan. Had her do a full virus scan.

    Step-dad's: (Dell Optiplex tweaked upgrades) Windows Defender not turned back on by default. Full Scan.

    Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

    Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

    • Open a new Explorer window.
    • Click View in the ribbon.
    • Click Options.
    • Under General, next to “Open File Explorer to:” choose “This PC.”
    • Click OK
