Problems solved by technology

[0003] Although the above method can fight against viruses to a certain extent, there are still shortcomings, mainly manifested in: many viruses will set hooks in the kernel state to prevent the antivirus software from loading the driver, resulting in the antivirus software being unable to load the driver, and unable to enter the kernel state to fight against the virus , and eventually the antivirus software cannot find the virus or delete the virus due to insufficient permissions

Abstract

The invention provides a file reading and writing method and device. The method comprises the following steps that: accessing hard disk equipment, reading raw data from the hard disk equipment, wherein the raw data is data of a byte stream form; analyzing the read raw data to obtain terminal system configuration parameters, wherein the terminal system configuration parameters comprise a file storage path in a terminal system; according to the terminal system configuration parameters, determining the storage path of target raw data corresponding to an appointed file in the hard disk equipment; and according to the storage path, searching the target raw data, and executing a read-write operation for the target raw data in the hard disk equipment. By use of the technical scheme, a whole read-write process is not limited by kernel mode permission, no drivers need to be loaded so as to avoid a situation that a file can not be normally read and written since driver loading is hindered when hooks are arranged in the kernel mode by malicious programs and the like, and a purpose that the file is read and written from a user mode is achieved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and device for reading and writing files. Background technique [0002] In the prior art, there is often such an antivirus scenario: a virus with a driver exists in the system earlier than the antivirus software, and the virus runs with kernel authority. Since user-mode permissions are lower than kernel-mode permissions, viruses can easily hide from antivirus software by intercepting file system access requests, preventing antivirus software from operating virus files, and even preventing antivirus software from running its own functions normally. To solve this problem, the existing solution in the industry is that the anti-virus software enters the kernel mode by loading the driver, and fights against the virus with the kernel mode authority. Obviously, as far as this kind of scheme is concerned, whether the driver can be successfully loaded is the key to succe...
