 General Comments: 
       The Lythyum virus was submitted in January, 1993, and is from the 
       United States.  Lythyum is a non-resident, direct action infector 
       of .COM programs, including COMMAND.COM.  It was written by a 
       member of the Virulent Graffiti virus writing group. 
       When a program infected with they Lythyum virus is executed, the 
       Lythyum virus will infect one .COM program located in the current 
       directory.  Infected programs will have a file length increase of 
       502 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 encrypted within the 
       Lythyum virus' code in infected programs: 
               "lythyum, the attitude adjuster, ViRuLeNT GRaFFiTi" 
               "\Lythyum.hi! *.COM" 
       Once the virus has infected all of the .COM files in the current 
       directory, it will create a hidden file, LYTHYUM.HI!, in the current 
       drive's root directory when the next infected program is executed. 
       The hidden file will contain the first text string indicated above. 
       Known variant(s) of Lythyum are: 
       Lythyum-B: Functionally similar to the Lythyum virus described 
                  above, Lythyum-B is a very minor variant. 
                  Origin:  United States  January, 1993.
