What’s sigverif.exe (File Signature Verification)? Is it safe or a virus?

Sigverif.exe is a built-in utility in Microsoft Windows that is used to verify the signatures of files on a Windows system.

When run, sigverif.exe scans all the files on the system and checks their digital signatures to ensure they are valid and have not been altered. Digital signatures are used to verify the authenticity and integrity of files, and sigverif.exe helps to identify any files that may be missing valid signatures or have been tampered with. This helps to ensure the security and reliability of the files on the system, and can be a valuable tool in troubleshooting potential issues related to file integrity.

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.
