 General Comments: 
       The Deranged virus was submitted in April, 1993.  Its origin or 
       point of isolation is unknown.  Deranged is a non-resident, direct 
       action infector of .EXE programs. 
       When a program infected with the Deranged virus is executed, the 
       Deranged virus will infect all of the .EXE programs located in the 
       current directory.  Beeping on the system speaker may then occur, 
       and/or possibly a system hang. 
       Programs infected with the Deranged virus will have a file length 
       increase of 419 bytes with the virus being located at the end of 
       the file.  The program's date and time in the DOS disk directory 
       listing will not be altered.  The following text strings are 
       visible within the viral code in all Deranged infected programs: 
               "*.EXE .." 
               "The Deranged Virus 1.0" 
               "Criminal Behaviour"
