F-Secure Virus Descriptions : Old Yankee

This virus is not directly related to the Yankee virus, although they share some code. This virus only infects .EXE files, increasing their length by 1961 bytes. When an infected program is run, the virus will search for a non-infected file. When it has been infected, the virus plays the melody, before the original program is executed. At the very end of the virus, the word "motherfucker" appears. A 1624 byte version of this virus is also known.

VARIANT:

Bandit, Enigma, Black Peter

Fairly non-interesting "laboratory" variants, not believed to exist in the wild.

VARIANT:

Black Wizard

In this 2051 byte variant the word at the end has been replaced by "Black Wizard", and the virus plays a different tune than the original.
