What’s opera.exe.old (Opera GX Internet Browser)? Is it safe or a virus?

Opera.exe.old aka Opera GX Internet Browser is a file that is created when the Opera web browser from Opera Norway AS is updated or replaced with a new version.

The .exe.old file typically contains the old version of the Opera executable program. This file is not actively used and is essentially a backup of the previous version of the Opera browser. It is common for software installation processes to preserve the old version in case the new version causes issues, so that users can revert back to the previous version if necessary. The .exe.old file is typically safe to delete once the new version of the Opera browser is successfully installed and running.

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.
