When executed, Jiskefet searches for NewEXE files. It reads the first 2,048 bytes from the file, then copies it to the end of the file. When this file is executed, the virus will create a temporary disinfected copy of the original file and execute it while infecting other files.


The virus was originally posted as source code to a bulletin board. It was coded by Masud Khafir in the Netherlands. Masud Khafir was responsible for other viruses such as Winvir, Pogue and Cruncher.


Masud Khafir named the virus after a popular Dutch comedy troupe, which broadcast shows from 1990 to 2005. The word "Jiskefet" means "trashcan" in Frisian, a language spoken in the north of the Netherlands, as well as parts of the Schleswig-Holstein and Lower Saxony states of Germany.
