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.

Technical Details


Variant:Danom.B

Danom.B virus infected .msh, .cmd and .bat files. If the infection marker "Candela" is not found, the virus infects by prepending its code. However .bat and .cmd infected files overwrite during infection.


Variant:Danom.A

This virus searches for .msh files and if such are found it looks for an infection marker "Candela". If the last is not present in the file, the virus appends its code to the victim file.


Variant:Danom.D

This is a small code written to overwrite .msh files with itself. It searches for such files and checks for the length. It tries to infect if the file size is different from the size of the initial infected file. However due to an error the virus infects one file per run. It infects the last file in alphabetical order, unless it is already infected.


Variant:Danom.E

This is similar to Danom.A but it prepends the virus code to the victim files.
