What’s dwengine.exe (Dr.Web Scanning Engine)? Is it safe or a virus?

The dwengine.exe process, developed by Doctor Web Ltd., is part of the Dr.Web antivirus suite and serves as the scanning engine responsible for detecting and addressing malicious software, viruses, and other security threats. It works by analyzing files, system activities, and incoming data to identify potential risks, ensuring the protection of the system. This engine operates as a core component of the antivirus software, running in the background to provide real-time scanning and on-demand virus checks. Its role is critical for maintaining system security, identifying vulnerabilities, and preventing malware infections by leveraging advanced detection algorithms and threat databases.

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.
