 General Comments: 
       The V801 virus was received in March, 1991 from the United States. 
       This virus is a non-resident, direct action infector of .COM and 
       .EXE programs.  It will infect COMMAND.COM. 
       When a program infected with V801 is executed, the virus will 
       search the current directory for an uninfected .EXE program.  If 
       one is found, it will infect the program.  If an uninfected .EXE 
       program is not found, the virus will then search for an uninfected 
       .COM program in the current directory, and infect it. 
       Programs infected with V801 will increase in size by 791 to 808 
       bytes.  .COM programs will have the virus located at their 
       beginning.  .EXE programs will have the virus located at the end of 
       the infected file. The program's date and time in the disk 
       directory will not be altered. 
       Some infected programs may cause a system hang when they are 
       attempted to be executed. 
       V801 doesn't appear to do anything besides replicate.
