    This is commonly caused by Windows security features blocking a DLL or app component that it can’t verify.

    Try these checks in order:

    1. Check Potentially Unwanted App protection
      • Open Windows Security.
      • Go to App & browser control > Reputation-based protection.
      • Review whether reputation-based protection is blocking the Quicken component.
      • If the PC is organization-managed, this setting might not be changeable.
    2. Check Smart App Control status
      • Open Settings > Windows Security > App and Browser Control.
      • Look for the Smart App Control section.
      • If it shows On, Smart App Control is enforcing blocks.
      • If it shows Evaluation, it is still assessing apps.
      • If it shows Off, Smart App Control is not the cause.
    3. If the blocked item is part of a legitimate app
      • For apps blocked by security software because files inside the app package are not individually digitally signed, the documented workaround is to add the affected app to the allow list of the security software.
    4. If Quicken is being blocked from protected folders during backup
      • Open Windows Security > Virus & threat protection.
      • Select Ransomware protection.
      • If Controlled folder access is enabled, allow Quicken through the protected folder list.

    If the warning is specifically about emc.dll, that indicates Windows is objecting to that loaded component rather than the backup file itself. The most relevant areas to review are App & browser control and, if backup folders are involved, Ransomware protection.

    Welcome Gwen O,

    Thanks for reaching out to Microsoft Q&A Forum. I understand that Windows Security displays a warning while you are backing up Quicken, stating that some features were blocked because the publisher of emc.dll could not be confirmed.

    Does the warning show the full file location for emc.dll? Also, did this start after a recent Quicken update or Windows update?

    Please make sure you already tried the Q&A Assist steps. In addition, please try the following:

    1, Check the location of emc.dll

    • When the warning appears, check whether it provides a file path or additional details.
    • Please share the file path shown for emc.dll, but remove any part containing your Windows username or other personal information.

    2, Repair or update Quicken

    • Open Quicken and check for available application updates.
    • If Quicken is already current, use its repair option if available, or reinstall it using the official Quicken installer.
    • This can replace an application component that may be damaged or incorrectly registered.

    3, Check Windows Security protection history

    • Open Windows Security.
    • Go to Virus & threat protection > Protection history.
    • Look for an entry corresponding to the time when the Quicken backup was attempted.
    • If you find one, please share the threat or action name shown there, without including personal information.

    4, Check whether Windows is fully updated

    • Go to Settings > Windows Update.
    • Select Check for updates and install any available Windows security or cumulative updates.
    • Restart the computer afterward and test the Quicken backup again.

    Looking forward to your update.
