This tool can perform a special immunity treatment on the selected disk, making its autorun feature ineffective, thus preventing viruses from immediately executing automatically when a virus-infected mobile disk is inserted into the computer. The tool also has the capability to repair system disk associations and disable the system's autorun feature, completely resolving the issue of being unable to open disks after some antivirus software removes viruses. Note: If no disk is selected, additional functions will be executed, i.e., repairing disk associations and disabling the system's autorun feature.
