 General Comments: 
       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." 
               "For more information call: ++1-408-988-3773 (USA)" 
       This virus appears to have been written by an individual wishing to 
       get the author of VSUM's attention.
