- └─────────────────────────────┘
-
- Date of Origin: September 30, 1989.
-
- Place of Origin: Sofia, Bulgaria.
-
- Host Machine: PC compatibles.
-
- Host Files: Remains resident. Infects COM, EXE files.
-
- OnScreen Symptoms: Plays "Yankee Doodle" on the system speaker some time
- after loading.
-
- Increase in Size of Infected Files: 2885 or 2899 bytes.
-
- Nature of Damage: Affects system run-time operation. Corrupts COM and
- EXE files.
-
- Detected by: Scanv42+, F-Prot.
-
- Removed by: CleanUp, Scan/D, VirClean, F-Prot, or delete infected files.
-
- This virus was written by Wladimir Bochev from Sofia, Bulgaria, as an
- intellectual exercise. It was discovered in Vienna by Alexander Holy at
- the United Nation's North Atlantic Project office on Sept 30th, 1989.
- The virus has reportedly been transmitted to the U.S. through U.N.
- employees via the game "Outrun".
-
- The virus plays the tune "Yankee Doodle Dandy" on the system's
- speaker either when the program is loaded, or 17 hours after an infected
- program is loaded, depending on the version of Yankee Doodle. Both COM
- and EXE files of any size can be infected, and the virus willingly
- infects every such file.
-
- Infected files grow in size by 2899 bytes. Infected files can be
- recognized by the string "motherfucker" at their ends. In the early
- versions, there was no damage caused by the virus. In fact, the virus was
- apparently designed as a virus fighter. It will seek out and modify Ping
- Pong viruses, changing them so that they self-destruct after 100
- infections. Subsequent strains may format the hard disk. Several
- variations on the Yankee Doodle virus have been identified. See entries
