What’s MessagingSDKReg.exe (McAfee NextGenMessaging Registrar)? Is it safe or a virus?

MessagingSDKReg.exe is a legitimate program associated with McAfee's security products, specifically the "NextGenMessaging Registrar." It is designed to facilitate communication between McAfee's tools and services, enabling features such as notifications, updates, or inter-process messaging within the security suite. As part of McAfee's infrastructure, the executable helps manage and register components necessary for the functionality of its messaging and communication system. While it is generally safe, if found in unexpected locations or exhibiting unusual behavior, it could be worth investigating for potential malware impersonation. This file ensures seamless operation and coordination of McAfee's security features across its applications.

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.
