What’s Win32FuncLoader.exe (360杀毒 扩展扫描插件)? Is it safe or a virus?

Win32FuncLoader.exe is a component of the 360 Total Security software developed by Qihoo 360 Software, a Chinese cybersecurity company. The application description "360杀毒 扩展扫描插件" translates to "360 Antivirus Extended Scanning Plugin," indicating its function as a scanning extension for the antivirus program. Its primary role is to facilitate system protection by supporting additional malware detection and handling tasks during scans.

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.
