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.
