i'd honestly rather send a turtle with TNT to blow it up, haha

+1 on that.



get the floppy your spreading the file via. Name the file "virus" for now. create a new file on the floppy called startup containing just this code:

fs.copy("disk/virus","startup")

Insert the floppy into the computers disk drive and reboot the computer. It will run the version of startup on the floppy. Startup on the floppy simply copies the floppies virus into the startup file of his terminal. Reboot is terminal and sit around for the lols. Do what you want in the virus program.

My personal favourite though is the TNT trap. Simply hide a block of tnt under his computer. Create a startup program that changes the alias shutdown to direct to a new program. The new program activates the TNT under the computer. Sit around and wait for the fireworks ;)/>/>
fs.copy("disk/virus","startup")

Create a file called startup and put it in the root directory of the target computer. It will run every time the computer starts.
To prevent the user from terminating the program with Ctrl-T, overwrite the os.pullEvent() function.

function os.pullEvent()
	return os.pullEventRaw()
end

while true do
	print("Problem?")
	os.sleep(1)
end

To get rid of a startup virus like this, create a floppy disk with an empty startup file in it, put a disk drive next to the infected computer, put the floppy disk in the disk drive and restart the computer with Ctrl-R. The computer will use the startup file on the floppy disk instead of running the one on itself.

Edit: Bah, you beat me to it. ;)/>/>

That part I did not know. Learn something new every day :P/>/>

I would do the tnt but i dont feel like putting the backup on the server all over again. and I want to charge him iron to fix his computer XD TroLLLL M0DE!

now is there any way to prevent the ctrl + r key? so that way i dont need to hide that disk drive. i just put the floppy in hit ctrl +r (to reset the computer) and then the virus prevents the ctrl+r key from being used so the script keeps going.

There is no way to prevent the ctrl + r key from being used. However you could delete the startup file of any disk that gets inserted <_</>/>

That however will not prevent the person from ctrl + s which will shutdown the computer, then they place the floppy with the startup and then proceed to start the computer.

If you want to bypass ALL of that, the only solution is to place a blank startup file in a disk-drive on TOP of the computer. Then you just have to find a way to protect that drive from being accessed :)/>/>

so put bedrock? lol (too bad we are all in creative in the server <_</>/>)
he still doesnt know about the ctrl+r or ctrl+s or ctrl+t which is good. I just wanted to know just in case. (he'll prob just break the computer and put it back lol)

Well, for a virus, you could try this one:

print "Now waiting 316,880,878,140,289,502,370,268.96 years"
while true do
  os.pullEventRaw()
end
sleep(10e100)
os.reboot()

If you put this in the startup, the only way out is to replace the computer. Yes, it really waits that long (I set the sleep time to a googol seconds)!

actually your program never even reaches that sleep

That does not brick a pc.

put this in startup:

term.clear()
term.setCursorPos(1,1)
password = "1234x"
print("CraftOS 1.3")
function trolol()
write("> ")
aba = read()
if aba == password then
  print("Access Granted.")
  print("Computer unlocked.")
else
  print("No such program")
  trolol()
end
end
trolol()

Every time they try to do something, it returns no such program. If they enter the password it will stop this (but will continue if they turn off computer)

Non password version:

term.clear()
term.setCursorPos(1,1)
print("CraftOS 1.3")
function trolol()
write("> ")
aba = read()
print("No such program")
trolol()
end
end
trolol()

that a good one ComputerCraftFan11 lol
