The main.cpp file is installed and used by keylogger Hooker Trojan Keylogger. It is also related to other parasites such as BOTool 1.0, DataSpy Network X and Enculator. These threats can use main.cpp for different purposes, as the file's functionality depends on a particular parasite it belongs to.
In some cases a presence of main.cpp 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 main.cpp file using you regular spyware remover or antivirus program.
