Motherboard BIOS is CIH virus destruction how to solve

The meaning of CIH virus

CIH virus is a kind of vicious virus that can destroy computer system hardware. According to the current material, the virus is produced in Taiwan, the first pirated CDs with the international pirate groups in the United States and other places widely disseminated, and then further spread through the Internet to all corners of the world.

CIH Virus transmission mode

The main route to CIH virus transmission is the Internet and e-mail, which, of course, will spread through floppy disks or CDs over time. It is reported that the authoritative virus collection network currently reported CIH virus, "original" plus "variant" a total of five species, the main difference is that "the original" will increase the infected file, but not destructive, and "variants" not only to the growth of infected documents, but also a very strong destructive, especially a "variant", Every month, 26th will attack.

The harm of Chi virus

Destroys all information on the user's system and, in some cases, overrides the system's BIOS. On the other hand, the BIOS for some computer motherboards is overwritten. After the BIOS is overwritten, the system will not start, only send the computer back to the factory repair, replace the BIOS chip. Because the CIH virus to the data and hardware damage is irreversible, so once the CIH virus outbreak, users can only watch the value of million computers and accumulated years of important data destroyed. CIH virus has now been identified as the first virus to destroy computer system hardware, but also the most lethal of the malignant virus.

The killing of Chi virus

Generally, if the computer network generally through the anti-virus software killing can kill the virus, the BIOS settings first users should determine their own computer motherboard BIOS is that type, if it is not upgradeable, users need to change back to the parameters of the CMOS can be reset. If the user's computer BIOS is upgradeable. If there are symptoms of a CIH virus outbreak, do not reboot the computer from the C disk boot system, but should be in time to enter the CMOS Setup program, the system boot disk set to a disk and then a disk boot system,

Of course, the above said there are anti-virus software killing, but the anti-virus software may cause damage to the system software after how to do it? First of all, use antivirus software to completely antivirus the hard disk, and then the system software and application software to reinstall. Can be installed directly on the basis of CIH virus damage, this method is simpler, but can cause waste of hard disk space, because it will bring some junk files, another way is to keep the user's important data, then format the hard disk, reinstall the system programs and applications, which can save hard disk space.
