  1. Hello,

    Is this consistent in every Windows session?
    Do you see the same behaviour in Safe Mode or with a clean boot (excluding Malwarebytes Service)?

    We haven't had any other reports of this and it's not reproducible, so we'll need additional information to track down the root cause.

    Could you start by gathering logs with the Malwarebytes Support Tool please?

  2. Hello,

    Thank you for the file.

    The logs indicate you were still on the old version when the most recent detection occurred. The product was only updated to the new beta version a few hours after the detection occurred.

    Now that you have the beta version installed, you shouldn't experience the issue.

    Just to add - while I know that the MLWB team is working on this, and there have been updates, the problem continues to occur - even worse for me - Winword, Outlook, Explorer, WinZip.  This is VERY frustrating.  


    Which issue are you referring to? The false-positive detections for Microsoft Office programs (Word, Excel, etc) or the performance issue with Windows 10 v2004 (or potentially something different entirely)?

    This forum topic is related to false-positive detections for Microsoft Office programs. You've mentioned programs such as Explorer and WinZip which are unrelated.

    if you are experiencing false-positive detections for Microsoft Office programs, we have a fix for this currently in beta. See here.
    If you're experiencing something else, please clarify the issue.

    Please provide logs as well using the Malwarebytes Support Tool:

  4. Thanks for the report. We'll look into why those folders weren't removed correctly.

    Regarding the registry leftovers you mentioned - note that there are many keys/values that may contain references to Malwarebytes but are not explicitly created by the product and are not appropriate to remove. This is the case with any software installation. The Support Tool does a very thorough job with removing registry keys/values. If you have any details on exactly what was leftover, we can certainly take a look.

  5. We have released a new beta update to address this issue (component package version 1.0.976).

    To obtain this beta update:

    • Enable beta updates if necessary by opening the Malwarebytes settings and turning the "Beta updates" setting on.
    • Click About followed by "Check for updates".
    • Note: If you have just started the computer, you may need to wait a few minutes before the update will be available to download.

    If you have configured any new exclusions as a result of this issue, we recommend removing them once component package version 1.0.976 or higher is installed. This can be achieved using the Allow List found in Detection History or Settings and should only be done after the new update is installed.

  6. @frozen To confirm, is the issue still not exhibited with the latest standalone Malwarebytes Anti-Ransomware?

    You mentioned the issue is not exhibited when using a different profile. Can you try a new/default profile located on a different drive so we can rule out if the contents of your profile has any impact?


    @PhoneNumberZero Is your Firefox profile also located on a different drive than the one Firefox is installed to?

    Could you also try the Malwarebytes Anti-Ransomware standalone linked above and see if the issue is still exhibited?

  7. Hi all,

    We are aware of an issue involving Ransomware Protection blocking Microsoft Office programs such as Word and Excel. We are actively investigating this issue and hope to provide a fix for this as soon as possible.

    For now, if you encounter a Microsoft Office block and are certain this is a false-positive, we recommend the following:

    • Restart Ransomware Protection by opening the Malwarebytes dashboard, toggling Ransomware Protection off and then back on again.
      • If you are still unable to launch the blocked Microsoft Office program, restart the computer.
    • Add a folder exclusion for the affected program (e.g. C:\Program Files (x86)\Microsoft Office\Office12).

    The steps above should prevent further blocks and allow you to resume normal usage of your Microsoft Office program.

    If you still encounter an issue after carrying out the steps above or would like confirmation on whether the block you encountered is a false-positive:

    In some circumstances, you may need to perform a repair of your Microsoft Office product if you are still unable to launch it after restarting the computer.
    See here for details: https://support.microsoft.com/en-us/office/repair-an-office-application-7821d4b6-7c1d-4205-aa0e-a6b40c5bb88b

    We will provide an update to this topic when available.

  8. Hello,

    Thank you for the logs. This was indeed a false-positive that we intend on releasing a fix for as soon as possible.

    In the meantime, if the issue does happen again, you may wish to add a folder exclusion for C:\Program Files (x86)\Microsoft Office\Office12 until the fix mentioned above is released.

  9. Hi @Chinook,

    Thank you for the logs.

    • Could you provide more detail on what you are specifically doing with Chrome when the block occurs?
    • Is it a consistent set of actions that result in the block occurring?
    • If you launch Chrome without extensions or plugins loaded, does the issue still occur?
      • Close all instances of Chrome.
      • Press the Windows Key + R on your keyboard at the same time and enter: Chrome.exe --disable-extensions --disable-plugins

    Please do the following:

    • Download and run Process Monitor: https://docs.microsoft.com/en-us/sysinternals/downloads/procmon
    • Reproduce the Chrome block.
    • Stop the Process Monitor capture (File -> click "Capture Events" to remove the checkmark).
    • Save the output (File -> click "Save..."), zip it up, upload to a file hosting service of your choice (WeTransfer.com, Google Drive, OneDrive, etc) and share the download link.
    • Rerun the Malwarebytes Support Tool, gather logs and attach the new mbst-grab-results.zip.

  10. Hi @OrangeSour,

    As mentioned above, rebooting the computer should be sufficient in resolving this. If you are running Windows 10, ensure the "Restart" option is used and not "Shut down".
    If you encounter the issue again, you will need to add a temporary exclusion for excel.exe until we can fix this issue. See here: https://support.malwarebytes.com/hc/en-us/articles/360038479234-Add-to-the-Allow-List-in-Malwarebytes-for-Windows-v4

    Please provide us with the mbst-grab-results.zip file created by the Malwarebytes Support Tool so we can take a closer look at the issue.
