    Windows Defender finds a threat every time I run a quick scan, but never can I find...


    Windows Defender always tells me it found a threat whenever I run a scan, even consecutively.

    But the Protection History is always empty just 'no recent operations'.

    Then I restarted the Windows Security Center as some suggestted, by these commands:

    reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender" /v "DisableAntiSpyware" /d 1 /t REG_DWORD /f

    reboot

    reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender" /v "DisableAntiSpyware" /d 0 /t REG_DWORD /freboot

    But still, one threat, and no history.

    :)

    Windows Defender - Quick Scan

    Windows defender no longer offers a quick scan option.

    My options are:

    • Scan
    • Advanced Scan
    • Full Scan
    • Custom Scan
    • Windows Defender Offline scan
    Whichever option I check, the scan will need to run for hours to complete.

    Is a quick scan available?

    How do I restore this feature?

    Yes. Malware includes all threats.

    Windows Defender Quick Scan question

    I just did a quick scan on my computer, when it was done in notifications area got message: Windows Defender scanned your PC At 1:42:10 on 2/28/2017 and took action against malicious software, but the windows defender screen said: Scan completed no threats
    detected during this scan. There is nothing listed in the history either, what does this mean?
