    Malware infection on Windows .dll files might be causing OneNote to crash when inserting...


    Hi.


    Recently my Microsoft OneNote crashed after updating Windows when inserting pdf, leading me to search about the resolution, in which I later saw an article online saying this might be due to corrupted system file.

    I also saw 2 dialog boxes saying my StartupCheckLibrary.dll and winscomrssrv.dll is having problem everytime I restart my computer.

    Then, I proceed to use Windows Defender and saw that there are 3 Trojan which are detected few days ago, affecting these .dll files.

    After I saw these malware detections, I ran a full scan on my computer using Windows Defender and discovered another malware.

    However, even after I block the new malware, I still can see the .dll file error on startup. Maybe because Windows disabled them

    Hence, I downloaded Malwarebytes and ran a scan, only discovering that there are another 21 malwares and 1 potential-unwanted program in my pc.
    Below are the scan details of Malwarebytes:

    After quarantining the malwares detected using Malwarebytes, now I do not see the StartupUpdateLibrary.dll error anymore.



    However, I suspect my computer has been infected. And those system files that are quarantined cannot be quarantine forever and I will need to use them some day.

    And also, my OneNote still crash when inserting pdf.

    When I use OneNote web client, I can see the pdf being inserted, but the content is not shown either.


    I would like to remove these malwares, but I afraid I will damage my computer. Could anyone help me? Thank you so much.

    :)

    Malware infection on Windows .dll files might be causing OneNote to crash when inserting...

    .DLL file

    Hi Jerry,

    Specific programs use DLL files to function properly in a Windows environment. If the DLL file gets misplaced, deleted, or corrupted, the error "____.dll is missing" appears. We'd like to learn more about your concern so that we could provide
    the proper resolution. We just have a few questions for you:

    • Which build version of Windows 10 is on your computer? To check, click
      Start      , type winver, and press Enter. For example, 14393.1066.
    • Did you make any changes to your computer before this started happening, like installing or uninstalling a program?
    • What troubleshooting steps have you done so far?

    As an initial recommendation, we suggest that you disable your Startup programs to isolate the cause of the error. To do this, follow these steps:

    • Right-click the taskbar and select Task Manager.
    • Click More details.
    • Go to the Startup tab.
    • Right-click every listed program and choose Disable.
    • Restart your computer and check if the issue persists.
    • If the error disappears, enable one of the programs and restart your computer to check if the error reappears; this is to pinpoint exactly which program is causing the error. Do this for all Startup programs until you find the cause.
    • Once you've found the program that's causing the error, you can then try uninstalling and reinstalling it.

    We'll wait for your response and the results of the troubleshooting.

    ----

    If you think this was useful, you may "mark it as an answer" to help those who are facing the same problem.
