The NeverMind virus was received in April, 1994. 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
"A WORD TO PATRICIA:"
"ER..........NAH, NEVER MIND"
"If this doesn't refer to you, just ignore it."
