What’s jmod.exe (OpenJDK Platform binary)? Is it safe or a virus?

`jmod.exe` is a command-line tool provided by OpenJDK, typically associated with the Java Development Kit (JDK), and is bundled under the generic description "OpenJDK Platform binary." It is used primarily to create, view, and manage JMOD files, which are a packaging format introduced in Java 9 for modular development. JMOD files are similar to JAR files but support native dependencies, configuration data, and other module-specific features. The tool facilitates the modularization of Java applications, enabling developers to build and distribute self-contained modules. It is targeted at developers working with the modular system introduced by the Java Platform Module System.

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.
