FITW infects COM and EXE files, boot sectors on both floppies and MBRs on hard drives.

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

The virus contains an encrypted text "Fart in the wind". The virus activates on certain dates. At this time, it will try to overwrite the hard disk with random data while displaying the following (otherwise encrypted) text. The text is displayed one at a time, displaying a new letter every time a key is pressed. Ctrl-Alt-Del is disabled during overwriting.


The "FartStorm" coded by Demon Emperor >Big hello to Cmoskiller & Xorboot< Are you wild? Hey don't... wait... let us talk... No? Be off lame fuckhead!

Due to a bad coding, the text does not always get displayed. Cmoskiller and Xorboot are names of two previous viruses that appeared in Slovenia during 1995.

Fitw is highly polymorphic, and it was the first virus to be really polymorphic in the boot sectors as well.


Variant:Fitw.3794

This is a smaller variant, which only infects COM and EXE files.

It activates on Mondays when the day of the month is 2, 4, 6 or 8.
