access denied when trying to run a program off of a floppy disk

This is supposed to be a virus file where the virus shuts down and doesn't allow the computer to do main functions, even with a simple antivirus program. This was planned to be used on one of my friends who is just starting tekkit but it is coming up with the access denied message. Please help!

Here's the code

print("I'm a virus :)/>/>")
fs.copy("disk/startup", "rom/programs/startup")
fs.copy(disk/delete, rom/programs/delete)
fs.copy(disk/edit, rom/programs/edit)
fs.copy(disk/lua, rom/programs/lua)
fs.copy(disk/move, rom/programs/move)
fs.copy(disk/rename, rom/programs/rename)
fs.copy(disk/shell, rom/programs/shell)
print("Bye, Bye")
sleep(1)
os.shutdown()

I know whats wrong, you cant edit rom ingame, sorry!

I know that you can name programs with the names pre-loaded on to the rom. Thats what I was trying to do

The shell will search two location for programs: the current folder and the programs folder. If the current folder (default: /) contains a file "edit", the real program "edit" isn't accessible any more. So you have to copy your programs to / and override cd too, tu be shure.

I got it to work!
This is what works.

print("I'm a virus :)/>/>")
fs.delete("disk/startup", "startup")
fs.delete("disk/delete", "delete")
fs.delete("disk/edit", "edit")
fs.delete("disk/lua", "lua")
fs.delete("disk/move", "move")
fs.delete("disk/rename", "rename")
fs.delete("disk/shell", "shell")
fs.copy("disk/startup", "startup")
fs.copy("disk/delete", "delete")
fs.copy("disk/edit", "edit")
fs.copy("disk/lua", "lua")
fs.copy("disk/move", "move")
fs.copy("disk/rename", "rename")
fs.copy("disk/shell", "shell")
sleep(1)
os.shutdown()

I believe that there is a function, shell.setAlias, but im not sure… Anyways, just /rom/programs/rm /rm and then delete anything, incase anyone needs to combat your virus :)/>/>
