Problems solved by technology
The disadvantage of disk restoration is that it can only restore the entire disk volume, which will affect the entire volume, and the protection granularity is too large. At the same time, disk restoration needs to intercept and analyze all disk operations of the system, so it will have a greater impact on system performance. big impact
In this way, if the user has other useful data that needs to be retained, it needs to be achieved through special means, which causes inconvenience in use

Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0017] Such as figure 1 Shown is the flow chart of initializing the environment protection. First, the initialization program will change the file name of the protection driver to a name input by the user, and install the protection driver in the boot loading mode in the system to be protected. This step is to prevent attacks against this protection scheme; then, create a configuration file with the same file name as the protection driver in the system32 directory of the system, the content is the startup file backup folder path (the program prompts the user to enter) and the uninstallation password (the program prompts the user for input). Next, create a startup file backup folder; there are three situations for initializing system startup files: 1. If the system startup files to be protected have been determined (for example, in a centralized compute...

The invention discloses a method for preventing an operating system starting file from being infected, which comprises the following steps: 1, initializing a protection environment, using boot to load and install a protection driver in a system, inputting the name of the protection driver by a user, setting up a backup system starting file folder, and setting up a driver configuration file in a system 32 list of the system; 2, intercepting file operation by the protection driver when the system is started, judging the type of a file, if the file is the system starting file of the backup file folder, stopping operation, if the file is the system starting file, carrying out next operation, and if the file is other files, allowing the operation; and 3, judging the type and the process of the file operation, if the operation is the operation process, opening the file in an Executive Image mode, taking over following reading operation by the protection driver, and reading corresponding files in the backup file folder, and if in other conditions, allowing the operation. By the method, viruses can not automatically run along the system starting to obtain the system control right through the mode of infecting the system starting file.
Description
technical field [0001] The invention relates to a method for preventing an operating system start-up file from being infected, in particular to a method for preventing a computer from being started after being infected by a virus. Background technique [0002] Computer virus is a major problem faced by computer applications nowadays. It can affect system performance, damage system stability, delete files, steal confidential information, and bring inconvenience to computer users and even economic losses. [0003] Two means have traditionally been used to tackle virus problems in computer usage. The first is anti-virus software technology. Its principle is that when the operating system is about to read a file or transmit data through the network, the anti-virus software module will first analyze the content of the file or data to determine whether it matches the predefined virus characteristics. . If it matches, it is considered to be poisonous, and the antivirus software w...
