 General Comments: 
       The Infector virus was submitted in December, 1992.  It is originally 
       from the USSR.  Infector is a non-resident, direct action infector of 
       .COM programs, including COMMAND.COM. 
 
       When a program infected with the Infector virus is executed, the 
       Infector virus will infect one .COM program located in the current 
       directory.  Infected programs will have a file length increase of 
       822 - 837 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 
       have been updated to the current system date and time.  The following 
       text string can be found in all Infector infected programs: 
 
               "*.COM" 
 
       Systems infected with the Infector virus will experience frequent 
       system hangs when infected programs are executed. 
 
       Known variant(s) of Infector are: 
       AReg-822: Received in November, 1993, AReg-822 is based on the 
                 Infector virus described above.  It infects one .COM file 
                 in the current directory, plus the copy of COMMAND.COM 
                 pointed to by the COMSPEC environmental variable if not 
                 previously infected, each time an infected program is 
                 executed.  Infected programs increase in size by 822 to 
                 837 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 have been updated to the current system date 
                 and time when infection occurred.  The following text 
                 strings are visible within the AReg-822 viral code: 
                 "*.com OMSPEC" 
                 ".com" 
                 "(C) 1993 AREG Soft" 
                 Origin:  Unknown  November, 1993.
