commands.c definition, relationships, removal:

This is a part of a malicious parasite that violates user privacy and damages the compromised system. The commands.c file can be used for different purposes depending on the related parasite's type, functionality and carried payload. Although commands.c may not take any malicious actions by itself, it ensures that a parasite is working properly and therefore needs to be removed. DO NOT open, execute or edit commands.c!
The commands.c file is installed and used by BO Unix 1.2.1. It is also related to other parasites such as Bogtk, BoScript and NIL 0.1b. These threats can use commands.c for different purposes, as the file's functionality depends on a particular parasite it belongs to.
In some cases a presence of commands.c does not mean that your system is infected. The file may actually belong to some fully legitimate applications and therefore must stay intact. If you are in doubt, please scan the commands.c file using you regular spyware remover or antivirus program.
