    How to Specify Scheduled Scan Type for Windows Defender Antivirus in Windows 10


    Windows Defender Antivirus.

    Windows Defender Antivirus 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.

    Windows Defender Antivirus regularly scans your device to help keep it safe. Windows tries to do this while you are not using your device so it doesnt interfere with your work. You can also schedule Windows Defender Antivirus to scan at a time and frequency that you choose.

    By default, Windows Defender Antivirus will perform a Quick Scan during a scheduled scan.

    This tutorial will show you how to specify to use a Quick Full scan type during a scheduled scan by Windows Defender Antivirus in Windows 10.

    You must be signed in as an administrator to specify a scheduled scan type to use for Windows Defender Antivirus.

  2. Scheduling Windows Defender scans

    Hi Gary,



    Thank you for writing to Microsoft Community Forums.



    I understand your query related to Scheduling Windows Defender Scan using Task Scheduler.



    Ideally, when you schedule a task using Task Scheduler it should run during the time. However, if the PC was not switched on at that particular interval then the scan might have taken place.



    You can try enabling the History of tasks in Task Scheduler to check more information.



    1. Press Windows key + R. This will open
      Run. Alternatively, you can go to Start and search for Run.
    2. In Run dialog box, type taskschd.mscand hit
      Enter.
    3. Now right click on the Action tab
    4. Select Enable All Tasks History


    You may also want to try changing the settings of the task that you have scheduled.



    1. Press Windows key + R. This will open
      Run. Alternatively, you can go to Start and search for Run.
    2. In Run dialog box, type taskschd.mscand hit
      Enter.
    3. Double click on the task that you have scheduled
    4. Under General tab, change the settings for
      when the task should run.
    5. Now under Settings tab adjust the settings
      as per your compatibility.


    For additional information, you can refer the articles below.

    scheduling Windows Defender full scan: problems and questions

    I have a new Windows 10 Pro 64 bit laptop that I am configuring. I am coming from a Windows 7 desktop. Much has changed.


    For its malware defense, I am using Windows Defender and Malwarebytes Premium.


    Scheduling Malwarebytes to scan at a certain time of day is trivial, but I have found it difficult to schedule Windows Defender to do a full scan.


    ~~~~~~~~~~

    I first tried to schedule Windows Defender using Schedule tasks as described here.


    That worked, except that I see no option to specify a full scan, so surely it is doing the default of a quick scan.

    Story to be continued below...


    ~~~~~~~~~~


    I next stumbled across other links that said that you can control many (all?) aspects of Windows Defender scans via Group Policy.


    The 3 best links being this, and this, and this.

    So, I opened Group Policy Management Editor and made these changes from the defaults:


    Code:
    Problem: when I try to make the "Specify the day of the week to run a scheduled scan" change above, after I click the OK button, the value changes from my Enabled setting to Disabled!

    What the heck is going on?


    My guess was that maybe I had some other setting that conflicted with this one, which was causing the auto reset to Disabled. I scoured thru all the settings, but found nothing.

    Please advise!


    Another problem: to see if a scheduled scan would take place, I tried temporarily changing the "Specify the time of day to run a scheduled scan" value to 2 minutes past my current time. When the current time reached that, no scan took place.


    Is the Group Policy alone insufficient to trigger a scan?


    ~~~~~~~~~~


    Doing more web searching, I eventually found out how to make Schedule tasks have Windows Defender do a full scan. As described in this link, you must supply these args to the MpCmdRun.exe program

    Code:
    Question: what is considered the best way to configure Windows? Using tools like Schedule tasks? Or should I always try to get stuff to work via Group Policy of possible?

    I am new to Group Policy, but it seems like the more official and thorough way. Please confirm or deny, and further enlighten me.

    ~~~~~~~~~~

    If Group Policy is the way to go, there is one more setting that concerns me.

    Under Scan is a "Specify the maximum depth to scan archive files" setting.

    The default is 0, which, if I understand the help text (and all links I found when searched), means that it scans to 0 depth. In other words, it does not drill down inside any directories at all!

    That sounds awful, and stupid. It also contradicts how a setting of 0 in other contexts means there is no limit.

    I want a setting that drills down as deep as necessary into the archive, I want everything scanned!

    Any way to achieve that?

    I suppose that I could specify a really large value, but that it is an inelegant hack that should not have to do.

  4. Specify Windows Defender Antivirus Scheduled Scan Type in Windows 10

    can't enable "Specify the day of the week to run a scheduled scan"

    run gpmc.msc (on a Server 2012 or Win10 machine with RSAT installed)

    Computer Configuration => Policies => Administrative Templates... => Windows Components => Windows Defender Antivirus => Scan

    "Check for the latest virus and spyware definitions before running a scheduled scan" is enabled

    "Specify the scan type to use for a scheduled scan" is enabled and options "Specify the scan type to use for a scheduled scan" set to quick scan

    HOWEVER:

    "Specify the day of the week to run a scheduled scan" gives me some grief: I enable it and select "Saturday" in the "Specify the day..." dropdown menu and OK (or Apply), but it stays not configured like I canceled the enable window. Any other specific day
    to no avail, but "every day" works (but I don't want every day).

    (I enabled "Specify the time of day to run a scheduled scan" but that didn't help, even set the turn off defender av and realtime protection to disabled; i.e. made sure those were explicitly on)

    I don't know what the default schedule is (and it seems to not be running on a bunch of my machines: maybe because we are edu versions?); anyway, just interested in forcing stuff on and have that default scan be on the weekends.
