Problems solved by technology
Because the Dos system uses character commands, it is not conducive to users to use; the Linux system has many problems in hardware compatibility, which is not conducive to users to maintain the system
At the same time, the operating system may still be infected by a virus, causing the system to crash or the anti-virus software to fail to run
[0003] In addition, in the known method of antivirus for virus-infected systems, the antivirus program cannot be synchronized with the latest existing virus database, and the user must manually upgrade the virus database through the network or the virus database upgrade package. To scan and kill system viruses
[0004] In addition, in the existing method, the dedicated antivirus platform is stored in a CD or floppy disk, and the user accesses the antivirus platform through the CD or floppy disk, and these media are easily lost, resulting in the user being unable to continue using the function

Embodiment Construction
[0028] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0029] as attached figure 2 As shown, it is a schematic diagram of the partition of the computer hard disk in the present invention.
[0030] Divide the system hard disk into HPA partition and ordinary disk partition. HPA (Hidden Protected Area) introduced the concept of "primary protection area" after the ATA-5 protocol was established. It is realized by directly protecting an area at the back of the hard disk with ATA commands. Not only the operating system cannot see this area , Even the motherboard BIOS cannot read the "main protection area" in the protected state. The HPA partition is a system hidden partition, which cannot be accessed by users under normal operating systems. In the HPA partition, it is divided into the following three parts:
[0031] (1) System HPA partition: keep a complete basic operating system bac...

The invention discloses a computer virus killing method, comprising the steps as followed: firstly, dividing the hard disk into a common disk partition and a system hiding partition HPA partition which comprises a system HPA partition kept with a backup for basic operating system, an HPA partition with the function of storing a system rescue software, and a real mode system positioned on the head address of HPA, writing the real mode bootstrap in the system boot sector of disk zero track, and directing the reading path to the head address of HPA partition; secondly, while starting the computer, enter the real mode system under the guiding of the real mode bootstrap; thirdly, the real mode system according to the differences of customer trigger signals, loading the backup operating system and starting the virus killing software stored in the function HPA partition, searching and killing virus in the computer. The invention has the advantages that since the mirror image of the backup operating system and virus killing software are stored in the HPA partition, they are difficult to be accessed, overwritten or infected by viruses under common operating system.
Description
Technical field: [0001] The invention relates to a new method for checking and killing computer viruses, and in particular to a method for checking and killing viruses on computers infected with viruses through a virus database shared by an independent anti-virus platform and a system based on the Windows platform. technical background: [0002] Among the existing computers, whether it is a notebook or a desktop computer, many of them have the ability to kill the virus-infected system through a dedicated anti-virus platform when the system is infected with a virus. The currently known anti-virus platforms are either based on Linux. The system is developed, or it is developed based on the Dos system, and there is no Windows system that users are generally familiar with. Because the Dos system uses character commands, it is not conducive to users to use; the Linux system has many problems in hardware compatibility, which is not conducive to users' maintenance of the system.
