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.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
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
