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.

We will provide an update to this topic when available.

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.
