...The Scores Virus

This is an application infector virus in the Macintosh environment that was
created in 1987 and infects any application program, increasing the program's
size by 7,000 bytes, and seeks out new hosts to infect every three and a half
minutes in its search for specific files to destroy.  A disgruntled ex-employee
of Electronic Data Systems appears to have created Scores to get back at the
company.

The first symptoms of a Scores infection are a slowing down of the system,
printing problems, increases in file size, and the small Mac icons for a
notepad and scrapbook changing into dog-eared pages.  

The harmful effects vary from system to system.  Sometimes data is destroyed,
in other infections the disk crashes, peripherals such as the printer will not 
work, or the rest of the system starts to dysfunction.  Sometimes Scores is 
triggered by the simple action of opening a file.  It is particularly annoying 
because it is so unpredicatable.  it seems probable that the person who 
originally wrote the Scores program did not want to harm anyone other than
EDS, but wrote a program that is a potential menace to every Mac user--one
that will continue to replicate and spread from machine to machine, searching
for EDS files.
