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.
Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.
A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:
Check for the latest database updates
First check if your F-Secure security program is using the latest updates, then try scanning the file again.
Submit a sample
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.
Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.
Exclude a file from further scanning
If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.
Note: You need administrative rights to change the settings.
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:
