Its origin or point of isolation is unknown. NeverMind is a memory resident infector of .COM programs, including COMMAND.COM. When the first NeverMind infected program is executed, this virus will install itself memory resident at the top of system memory but below the 640K DOS boundary, not moving interrupt 12's return. Total system and available free memory, as indicated by the DOS CHKDSK program, will have decreased by 1,680 bytes. Interrupt 21 will be hooked by the virus in memory. Once memory resident, this virus infects .COM programs when they are executed. Infected programs have a file length increase of 838 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 NeverMind viral code: "A WORD TO PATRICIA:" "ER..........NAH, NEVER MIND" "If this doesn't refer to you, just ignore it."
