The sfsync04.sys process is a system file that is part of the Frontline Synchronization Driver of the software StarForce Protection Frontline version 4 developed by Protection Technology (StarForce). As a system file, it is a device driver that helps in the configuration and reading of the program file StarForce during startup. The program StarForce Frontline version 4 is a basic computer protection system for 64-bit applications. It is compatible for Windows Vista and 32 or 64-bit operating systems of Windows. The program controls licensed applications for protection in the user PC. The users can choose which license to use to start protected applications by StarForce. The license choice is defined through serial number. Firewalls and activation protocol via proxy are more improved in version 4 compared to other versions. The time set on the user PC is no longer the basis during activation of any application. It means that protection against clock backward setting is implemented to prevent usage of expired licensed applications.
