 General Comments: 
       The Marked-X virus was submitted in August, 1994.  Its origin or 
       point of isolation is unknown.  Marked-X is a memory resident 
       overwriting virus which infects .COM and .EXE programs, including 
       When the first Marked-X infected program is executed, this virus 
       will install itself memory resident as a low system memory TSR, 
       hooking interrupt 21.  A system hang may occur, the user may be 
       returned to the DOS prompt, or other unexpected results may then 
       Once the Marked-X virus is memory resident, it will infect .COM and 
       .EXE programs when they are executed.  Infected programs will have 
       the first 354 bytes overwritten by the viral code.  The file's date 
       and time in the DOS disk directory listing will appear to have 
       "disappeared", though it will have actually been set to a value of 
       "0-00-80 12:00:00 am".  The following text strings are visible within 
       the viral code in all infected programs: 
               "Will we ever learn to talk with eachother?" 
               "(c) Metal Militia/Immortal Riot" 
               "In any country, prison is where society sends it's" 
               "failures, but in this country society itself is faily" 
               "Bad command or filename" 
       The last text string may be displayed as a message when infected 
       programs are executed. 
       Marked-X permanently corrupts the programs it infects.  All infected 
       programs should be deleted and replaced with uninfected backup
