Abstract: In example embodiments described herein, a device driver is employed to protect certain files. The device driver registers itself with an operating system and requests system notifications when a process attempts to delete, write data, or change attributes of a file. The device driver intercepts messages to delete, write data, or change attributes of a file and determines whether the request is for a protected file. If the request is for a protected file, the request is denied.

Abstract translation: 在本文描述的示例实施例中，采用设备驱动程序来保护某些文件。 设备驱动程序向操作系统注册自身，并在进程尝试删除，写入数据或更改文件属性时请求系统通知。 设备驱动程序拦截消息以删除，写入数据或更改文件的属性，并确定请求是否为受保护的文件。 如果请求是受保护的文件，请求被拒绝。
