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 programs: "KuDSR" Once all of the .COM files in the current directory have become infected, an unexpected system reboot may occur.
