False Positive - MB Blocking Power-User Add-on For Office

[COSMICX]

There's a legitimate add-on for Microsoft called Power-User and Malwarebyte's keep flagging it as a malware/exploit when it tries to do an update. This tool is legitimate and since it is an add-on that customizes/adds functionality to Microsoft Excel, I assume Malwarebytes flags it as an exploit.

First, make sure the following is not enabled.

If it is not, you will need to disable the following.

Doing this does solve the issue but won't disabling this mean even malicious applications will now be able to execute an exploit?

Yes. That is the risk/cost of using add-ons.

I see. Is it not possible for the MB team to whitelist it, so other users using the same app don't face an issue and users that do use it don't have to disable their protection settings and be vulnerable to actually malicious add-ons?

 

PS: Thank you so much for all your help, though. I really appreciate it.
