Kompu, Kommi


For more information on Word macro viruses, see WordMacro/Concept.

WordMacro/Kompu was found from Estonia in December 1996. It spreads when infected DOC files are opened to Word. After this, all other documents will get infected when they are opened or closed.


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 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

On the 6th or 8th of any month, the virus activates. When any document is opened on these dates, the virus will display a dialog box with the title "Mul on paha tuju!" and the question "Tahan kommi!". These texts are in Estonian and mean "I'm in a bad mood" and "Give me a candy". The virus will not let the user continue working until he writes the word 'komm' (candy) to the window. After this, the virus changes the Word status bar text to read:


Kompu.A has been reported to be in the wild in several European countries.

Variant:Kompu.I (Spreader)


This is another variant of Estonian virus Kompu. It was found in November 1997.

Kompu.I activates by switching to normal view and setting document magnification to 200 percent.

This happens every time an infected document is opened. At this time virus also displays a message box with the following text:

Still don't see the text ? I'll fix that problem ;)

The virus body contains this text:
