 General Comments: 
       The Quake virus was isolated in The Netherlands in May, 1992.  It 
       is a memory resident infector of .EXE programs with a very 
       noticeable screen effect. 
       The first time a program infected with the Quake virus is executed, 
       the Quake virus will install itself memory resident in the DOS 
       buffers.  There will be no change to total system and available 
       free memory. 
       Once the Quake virus is resident, it will infect .EXE programs 
       when they are executed.  Infected programs will have a file length 
       increase of 518 to 532 bytes with the virus being located at the 
       end of the infected file.  The program's date and time in the DOS 
       disk directory listing will not be altered.  There are no text 
       strings visible within the viral code. 
       Systems infected with the Quake virus will experience shaking or 
       "quaking" of all but the bottom line of the system display.  This 
       effect occurs every few minutes.
