Chinese_Fish is only able to infect a hard disk when you try to boot the machine from an infected diskette. At this time Chinese_Fish infects the Main Boot Record, and after that it will go resident to high DOS memory during every boot-up from the hard disk.
Disinfection & Removal
Virus uses stealth routines, so it cannot be found when it is active in memory. F-Secure anti-virus products will detect if Chinese_Fish is resident, and will advise you to boot from a clean diskette.
Chinese_Fish tries to remove some versions of the Stoned virus from infected disks.
Sometimes the virus displays the following message:
Hello! I am FISH, please don't kill me. Congratulate 80th year of the Republic Of China Building,Fish will help to kill stone Written by Fish in NTIT. TAIWAIN 80.10.18
