Summary

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.

Additional Details

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.
