Synonyms: Music virus, Musician virus.
|
|||
|
|
|
|||
|
|
Date of Origin: December, 1989.
|
|||
|
|
|
|||
|
|
Host Machine: PC compatibles.
|
|||
|
|
|
|||
|
|
Host Files: Remains resident; infects COM files.
|
|||
|
|
|
|||
|
|
Increase in Size of Infected Files: length increases by 2756-2806 bytes,
|
|||
|
|
so that total length is evenly divisible by 51. Most common length
|
|||
|
|
increase is 2,773 bytes.
|
|||
|
|
|
|||
|
|
Nature of Damage: Affects system run-time operation; corrupts program
|
|||
|
|
files.
|
|||
|
|
|
|||
|
|
Detected by: Scanv53+, F-Prot, IBM Scan, Pro-Scan.
|
|||
|
|
|
|||
|
|
Removed by: CleanUp, SCAN/D, F-Prot, or delete infected files.
|
|||
|
|
|
|||
|
|
A memory resident virus infecting COM files. When an infected
|
|||
|
|
application is executed, the virus installs in memory trapping the DOS
|
|||
|
|
21h interrupt. Thereafter, when a program attempts to create a
|
|||
|
|
subdirectory, remove a subdirectory, create a file, open a file, delete
|
|||
|
|
a file, get/set file attributes, rename a file, delete a file (with FCB),
|
|||
|
|
create file (with FCB) or rename a file (with FCB), one COM file is
|
|||
|
|
infected in the home directory. COMMAND.COM, COM files with length
|
|||
|
|
divisible by 51, COM files with an attribute other than normal or
|
|||
|
|
archive, or COM files with a length of 61980 bytes will not be infected.
|
|||
|
|
The virus seems to activate randomly after infecting a file. If
|
|||
|
|
activated, five minutes after infection it will play 3 or 6 melodies
|
|||
|
|
(depending on version) repeatedly with a 7 minute interval in between
|
|||
|
|
each.
