 General Comments: 
       The Returns virus was discovered in the United States on April 15, 
       1992.  Returns is a memory resident infector of .EXE programs. 
       When the first program infected with the Returns virus is 
       executed, this virus will install itself memory resident in 
       available free memory and in memory on the video card if it is 
       available.  Interrupt 21 is directly hooked by the virus in the 
       interrupt area. 
       Once Returns is memory resident, it will infect .EXE programs 
       when they are executed.  Infected programs will have a file length 
       increase of 512 bytes with the virus being located at the end of 
       the infected file.  The program's date and time in the DOS disk 
       directory listing will not be altered.  No text strings are visible 
       within the Returns virus in infected files. 
       It is unknown what Returns does besides replicate.
