Dinamo

Summary

Dinamo is yet another Russian boot sector virus. It has been found in the wild in Europe and Asia. Reports of Dinamo have been received from Hong Kong, China, Denmark and Finland. The virus infects MBRs and diskette boot records in the normal manner. Dinamo is not a stealth virus.

The virus gives the only visible sign of its presence if it encounters an error while reading the boot sector. Then it will display the following text and beep the speaker three times:

Dinamo(Kiev)-champion !!!

This text is encrypted with a XOR BDh operation, but the virus is not otherwise encrypted.

Virus will preserve the original partition table in it's correct form, so it can be disinfected with FDISK /MBR on hard disks. SYS works for floppies.

Removal

Automatic action

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.

Suspect a file is incorrectly detected (a False Positive)?

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 detection database 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.
