Browser homepage locking method

The invention discloses a browser homepage locking method. A process creation interface injection subsystem in the method adopts an injection or intercept mode, so that an operating system is invoked to the process creation interface injection subsystem before a process creation interface core code of a bottom layer of the operating system is executed, and then process starting information is submitted to a browser homepage locking monitoring and filtering subsystem and is checked, compared and modified through the two subsystems to enable a browser homepage to be locked. The method is performed before the operating system executes the process creation interface core code on the bottom layer of the operating system, so that falsification of rogue software and malicious software can be effectively prevented, the safety of a browser is improved, and individuation setting of the browser homepage is protected. In addition, the method achieves browser homepage locking through a process creation interface of the op
