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.
