 General Comments: 
       This virus was first reported by Yuval Tal of Israel in October, 
       1989.  The virus will infect .COM files, but only the first one in 
       the current directory, whether it was previously infected or not. 
       The Do-Nothing virus is also memory resident, always installing 
       itself to memory address 9800:100h, and can only infect systems with 
       640K of memory. The virus does not protect this area of memory in 
       any way, and other programs which use this area will overwrite it in 
       memory, removing the virus from memory. 
       The Do-Nothing virus does no apparent damage, nor does it affect 
       operation of the system in any observable way, thus its name.
