Many people now use the NTFS partition format, especially on servers. However, once an NTFS partition is infected, it is quite difficult to completely clear the virus. If possible, find a normal Windows 2000/XP system and use the infected hard disk as the slave disk. After entering the normal system, start anti-virus software to scan for viruses on toxic hard disks. Note that when mounting a slave disk, it is best to set the IDE interface other than the primary hard disk in BIOS settings to NONE or NULL to avoid accidental operation of the toxic system due to the drive letter crossover. This method is effective for all Windows 2000/XP systems, including servers using disk arrays. At the same time, we recommend that you press the F8 key and select safe mode when Starting Windows 2000/XP. At this time, the system automatically loads the least service processes. At the same time, it is recommended that you do not open other programs to allow antivirus software to complete antivirus work in a "specific" manner.
