Threat Description

Old Yankee


Category: Malware
Type: Virus
Platform: W32
Aliases: 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.
