When this virus activates it will just repeatedly play three melodies.
Infected files grow by a variable number of bytes, so their length becomes
a multiple of 51 bytes in length. This virus stays resident in memory, but
it will not infect other programs when they are executed. Instead it will
search for a file to infect when files are created or deleted, a
subdirectory is created or the access mode of a file is changed. A few
other functions may also trigger an infection.
The virus uses a random number generator to decide when to become active,
and if it does, it will start playing 5 minutes after an infected program
