  2. 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?

  3. Windows Defender quick scan fails to complete

    When I try to employ a "Quick Scan" procedure in Defender, the scan progress indicator, coloured green, stops half way and does not complete.

    The files scanned number continues the count as if it is doing a full scan.

    My Windows 10 updates are correct as our the virus definitions etc.

    Any suggestions on why the "quick" scan fails to complete?

    Thanks

  4. How accurate is quick scan on windows defender?

    Does Windows Defender Quick scan interrupt Advanced scan?

    Before I create a System Image, I run an Advanced scan using Windows Defender, and it typically takes about an hour and the Scan history lists about 4,000,000 files scanned. However, often I see only about 40,000 files scanned, what I get from a Quick scan.

    I can think of two explanations that might account for this:

    1. The Advanced scan completes, but a Quick scan starts afterwards and wipes out evidence that that the Advanced scan occurred (unless presumably some problem was found).

    2. The Advanced scan is interrupted and a Quick scan runs.

    Are there other possibilities?

    The 2 possibilities listed above are both unsatisfactory because I can tell if an Advanced scan was completed. If an Advanced scan was just completed, there is no reason that a Quick scan should be run automatically.
