 General Comments: 
       The RSP-1876 virus was received in November, 1991.  Its origin is 
       unknown.  RSP-1876 is a memory resident infector of .COM and .EXE 
       programs, including COMMAND.COM. 
       When the first RSP-1876 infected program is executed, this virus 
       will install itself in low system memory similar to a TSR.  The area 
       will not appear as a TSR, however, with most memory mapping 
       utilities.  Interrupts 21 and 22 will be hooked by the virus in 
       Once RSP-1876 is memory resident, it will infect .COM and .EXE 
       programs when they are executed.  If COMMAND.COM is executed, it will 
       also become infected.  Infected programs increase in size by 
       1,876 bytes with the virus being located at the end of the file. 
       The file's date and time in a DOS disk directory listing will not 
       have been altered.  The following text string can be found within 
       the viral code in infected files: 
       Execution of RSP-1876 infected programs may result in beeping being 
       emitted from the system speaker, as well as randome characters from 
       system memory being written to the system display.  System hangs 
       may also occur.
