-
- The following sections describe all of the known Mac viruses.
-
-
-
- xThe Scores Virus
-
-
- According to news reports, the Scores virus was written by a disgruntled
-
- programmer. It specifically attacks two applications which were under
-
- development at his former company. Fortunately, neither of the two
-
- applications was ever released to the general public. Scores was first
-
- discovered in the Spring of 1988.
-
-
- Scores is also sometimes known as the “Eric,” “Vult,” “NASA,” and
-
- “San Jose Flu” virus.
-
-
- There is an easy way to see if you have a Scores infection. Open your
-
- System folder and check the icons for the Note Pad and Scrapbook files.
-
- They should have distinctive icons under System 7, or look like little
-
- Macintoshes under System 6. If they look instead like blank sheets of
-
- paper with turned-down corners, your software may have been infected
-
- by Scores.

-
- It is possible to be partially infected by Scores and still have normal Note
-
- Pad and Scrapbook icons. Consequently, we recommend running
-
- Disinfectant to make certain your system is not infected, even if you have
-
- normal icons.
-
-
- Scores infects your System, Note Pad, and Scrapbook system files. It
-
- also creates two invisible files in your System folder named “Scores”
-
- and “Desktop ”. You cannot see invisible files without the aid of ResEdit
-
- or some other utility program. Do not confuse Scores’ invisible Desktop
-
- file with the Finder’s invisible Desktop file; they have nothing to do with
-
- each other. The Finder’s Desktop file lives at the root level on your disk,
-
- outside the System folder, while Scores’ Desktop file lives inside the
-
- System folder. Also, Scores’ Desktop file has an extra space character at
-
- the end of its name.
-
-
- Scores does not infect or modify document files, only applications and
-
- system files.
-
-
- Scores gets its name from the invisible “Scores” file that it creates.
-
-
- Two days after your system becomes infected, Scores begins to spread to
-
- each application you run. The infection occurs between two and three
-
- minutes after you begin the application. The Finder and DA Handler usually
-
- also become infected. For technical reasons, some applications are
-
- immune to infection.
-
-
- Scores does not intentionally try to do any damage other than to spread
-
- itself and attack the two specific applications. It does occupy memory and
-
- disk space, however, and this can cause problems all by itself. People
-
- have reported problems printing and using MacDraw and Excel. There are
-
- also several errors in Scores which could cause system crashes or other
-
- unexplained behavior.
-
-
- There is a serious conflict between Scores and Apple’s System Software
-
- release 6.0.4 and later releases of System 6. In System 6.0.4, Apple
-
- began using some resources with the same type and ID as those used by
-
- Scores. When Scores infects the System file, it replaces Apple’s versions
-
- of these resources with the Scores viral versions of the resources. When
-
- Disinfectant repairs the file, it deletes the Scores viral resources, but it
-
- does not replace the Apple versions. In this situation, Disinfectant issues
-
- a special error message, telling you that the resulting file is damaged and
-
- should not be used. You should immediately delete the damaged System file
-
- and replace it with a copy from original locked Apple release disks.
