What’s 64BitMAPIBroker.exe (Adobe Acrobat 64BitMAPIBroker)? Is it safe or a virus?

The 64BitMAPIBroker.exe is a background process created by Adobe Systems, Incorporated as part of Adobe Acrobat.

Its primary purpose is to facilitate email-related functions, specifically handling the integration between Acrobat and 64-bit email clients that use MAPI (Messaging Application Programming Interface). It enables users to send documents directly from Acrobat via email without switching to their email application.

This integration is particularly useful for streamlining workflows and sharing documents efficiently. As a helper process, it runs when required, ensuring smooth interoperability between Acrobat and supported email clients in a 64-bit environment.

What does it mean if someone is the publisher of a PC .exe (executable or process)?

The publisher of an executable is the entity responsible for its distribution and authenticity. Most processes/executables on your PC should be signed. The signature on the executable should have been verified through a third party whose job it is to make sure the entity is who it says it is. Find an unsigned executable? You should consider scanning any completely unsigned .exe on your PC.
