According to the different levels of damage caused by a virus, corresponding emergency measures can be taken to minimize the loss. Below are some common remedial methods for different types of virus damage:
1. **Flash BIOS Damage**: Rewrite the BIOS program (usually requires professional technical personnel) or replace the motherboard.
2. **CMOS Damage**: Discharge the CMOS and then reset it using the computer's setup program.
3. **Damage to the Boot Sector or Master Boot Record**: Some antivirus software can back up and restore the system's master boot record and boot sector information. Use this feature to restore. If you can find another computer with the same type of hard drive, similar partitioning, and the same operating system installed, you can use it to create a backup and then restore the damaged boot sector or master boot record caused by the virus.
4. **File Loss**: If there is a backup file, any damage caused by the virus to the disk can be restored through the backup file. If there is no backup file, more complex operations may be required, such as when part of the file allocation table is damaged. In such cases, professional technical personnel should be consulted. For these more complex situations, assistance can be sought from relevant individuals or companies.
