 General Comments: 
       The Dinky virus was received in January, 1995.  Its origin or 
       point of isolation is unknown.  Dinky is a memory resident 
       infector of .COM files, including COMMAND.COM. 
       When the first Dinky infected program is executed, this virus 
       will install itself memory resident in allocated system memory, 
       usually in a DOS buffer.  Interrupt 21 will be hooked by the 
       virus in memory. 
       Once the Dinky virus is memory resident, it will infect .COM 
       files when they are executed.  Infected .COM files will have a 
       file length increase of 122 bytes with the virus being located 
       at the beginning 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 string is visible within the viral code in all Dinky infected 
       Once all of the .COM files in the current directory have become 
       infected, an unexpected system reboot may occur.
