What’s FileIOSurrogate.exe (File I/O surrogate (not visible))? Is it safe or a virus?

FileIOSurrogate.exe is a legitimate executable developed by Sony Creative Software Inc., primarily associated with the VEGAS Pro video editing suite. Its main function is to act as a bridge between 64-bit versions of VEGAS Pro and 32-bit components, such as certain codecs or plugins. This is particularly important for handling media formats like QuickTime, which may rely on 32-bit architecture. By facilitating this interaction, FileIOSurrogate.exe enables VEGAS Pro to process a wider range of media files.

If you find FileIOSurrogate.exe on your system, it's likely because you have VEGAS Pro installed, and the application uses this executable to manage specific file input/output operations. It's a background process that typically runs when VEGAS Pro is active and is essential for certain media handling tasks.

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.
