[LUA] fs.delete("startup")

I keep getting error saying Access Denied! :S

Are you trying to delete the startup in rom?

Yeah :S
There must be something wrong with my Anti-Virus, because after it runs, you can't do anything to 'startup'. Can't edit it, can't delete it etc.
Here's the code:

if fs.exists('startupb') then
fs.delete("startup")
fs.copy("startupb","startup")
term.clear()
term.setCursorPos(1,1)
print("BlackRa1n Anti-Virus 1.0")
print("-----------------------------")
print("")
print("All Infected Files Removed From System!")
print("System will now reboot!")
disk.eject("right")
sleep(7)
os.reboot()
else end 
term.clear()
term.setCursorPos(1,1)
print("BlackRa1n Anti-Virus 1.0")
print("-----------------------------")
print("")
f = io.open("startup","w")
f:write("")
f:close()
print("All Infected Files Removed From System!")
print("System will now reboot!")
disk.eject("right")
sleep(7)
os.reboot()

It's really messy and not to well put together, mind telling me what's wrong with it?

I didn't get any errors…

If you run that program off of a floppy and name it 'startup' like I did you might. If you don't try typing: edit startup
And then type something.

Still no errors… Did you reboot the computer to run the program? Or did you cd to the disk and then run startup?

I inserted the floppy and then rebooted.

Hm, did you have something else on the computer/disk?

Try this, it will copy startupb from the disk into your pc

'startupb' isn't in the cd. It's in the terminal and I need 'startup' to be deleted and then 'startupb' to be renamed or copied into 'startup'

Perfect! Now the only problem is is the f:delete on my other code (The Virus for the Anti-Virus). Mind taking a look at that for me? This is the program that creates the 'startupb' by creating a backup of 'startup', deleting 'startup' and then changing 'startup' so it shuts off computer.

term.clear() 
term.setCursorPos(1,1) 
if fs.exists('startup') then
fs.copy('startup','startupb')
fs.close()
print("Installing:") 
sleep(2) 
print("20% Complete!") 
sleep(1) 
print("30% Complete!") 
sleep(2) 
print("50% Complete!") 
sleep(3) 
print("80% Complete!") 
sleep(2) 
print("100% Complete!") 
fs.delete("startup")
fs.copy("/disk/virus","startup") 
textutils.slowPrint("Virus Install Successful!") 
sleep(2) 
textutils.slowPrint("Terminal will now reboot!") 
sleep(2) 
os.reboot()
else
term.clear()
term.setCursorPos(1,1)
print("Installing:") 
sleep(2) 
print("20% Complete!") 
sleep(1) 
print("30% Complete!") 
sleep(2) 
print("50% Complete!") 
sleep(3) 
print("80% Complete!") 
sleep(2) 
print("100% Complete!") 
fs.copy("/disk/virus","startup") 
textutils.slowPrint("Virus Install Successful!") 
sleep(2) 
textutils.slowPrint("Terminal will now reboot!") 
sleep(2) 
os.reboot()
end

not sure whats wrong with that…

There is no function called fs.close(). Remove it (line 5).
