The company’s first product was the OpenCandy Advertising Network, which powers user-friendly software recommendations during the download and installation process. To date, the OpenCandy Network has driven over 600 million monetized software installs from hundreds of partners".

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.
