Its origin or point of isolation is unknown. Elvis-1250 is a memory resident infector of .COM programs, but not COMMAND.COM. When the first Elvis-1250 infected program is executed, the Elvis- 1250 virus will install itself memory resident as a low system memory TSR of 784 bytes. Interrupt 08 will be hooked by the virus in memory. Once the Elvis-1250 virus is memory resident, it will infect .COM programs other than COMMAND.COM, when they are executed. Infected programs will have a file length increase of 1,250 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 Elvis-1250 virus' code, and are not visible within infected programs: "ELVIS" "lives!" "is watching!" "DON_Maybe he lives here..." "Is he really dead? Or Here?" "Maybe he has a neighbour next door... (You can make up stories as you go along." "(C)1991 Elvis/VFriend, INC. All rights reserved." "
