Embodiment Construction

[0036] Before loading the boot sector of the boot device, the present invention detects whether the boot sector of the storage device contains a preset signature of a boot virus, and clears the boot virus when it is detected. Before the boot sector is loaded, the boot virus has not started to execute, and the MBR or DBR data has not been read into the memory and executed, so it cannot cover itself, so that the killing of the boot virus is more accurate and effective.

[0037] Such as figure 1 As shown, the method for killing the guided virus provided by the invention comprises the following steps:

[0038] Step S10, power on the power, hardware initialization settings.

[0039] Step S20, detecting whether the boot sector of the storage device contains a preset signature of a boot virus, if so, proceed to step S30, otherwise proceed to step S40.

[0040] In one embodiment, the storage device may include multiple storage devices. After the hardware initialization setting proce...

Abstract

The present invention relates to the field of computer technology, and provides a method for checking and killing boot-type viruses. The method includes the following steps: powering on and powering on, hardware initialization and setting; detecting whether the boot sector of a storage device contains a preset boot-type virus If the feature is identified, then the boot virus is removed; the boot sector of the boot device is loaded to boot into the operating system. The invention detects the boot virus before loading the boot sector of the boot device, so that the scanning and killing of the boot virus is more accurate and effective. In addition, the invention also provides a system for checking and killing boot viruses.

Description

【Technical field】 [0001] The invention relates to the field of computer technology, in particular to a method and system for checking and killing boot-type viruses. 【Background technique】 [0002] The master boot sector of the hard disk format storage device is located in the 0 track 0 cylinder 1 sector of the entire hard disk, that is, the first sector (also called the master boot record MBR), including the hard disk master boot record, partition information table and master boot record end sign Character; hard disk format devices usually include multiple partitions, each partition has a partition boot record (DOS Boot Record, DBR), and MBR does not belong to any partition. The DBR of each partition is located in the first sector of each partition. If the system startup program of the computer is installed on the hard disk format storage device, after power on, the MBR will be read into the memory through the BIOS interrupt service program, and then one of the partitions w...
