Hello. I am going to give you the code to "prank" your friends or people you don't like on your server. This makes it so the computer is unusable.
Spoiler
Put this code into startup file. When the computer starts up, type
edit startup
You'll be showen a blank screen. Type in that code for endless 'lolz'!

This is simpler and shorter
shell.resolveProgram = function() end

This is full of troll! And this makes it so they think they're making a mistake.

1. Make a floppy disk
2. Create a startup file
3. Insert the floppy disk on a disk drive
4. Profit!

Misnamed as a virus. Should just be a troll program. Virus indicates that it overwrites previous coding for malicious intent.

One Time, I had a program that (how 1lann said it) Ruined the whole Computer!
No Str+R, Str+S, Str+T and so on...
But he deleted the file and so I don't know the code of the vire anymore...
"But isn't the System hardcoded?"
Yes, but I know what I saw!

I think the Ctrl+R and Ctrl+S function is hardcoded?
One time I "deleted" the os.shutdown function and Ctrl+S still worked.
And i typed coroutine.yield=function() end and I reboote the PC using Ctrl+R.

So, if a program on your actual computer rendered it unusable, that wouldn't be malicious? I would certainly consider it to be.

Did you test this on computercraft itself, not just an emulator? I'm thinking that would just throw a "too long without yielding".

It don't changes programs and don't deletes programs.

Files may not be changed, but it still prevents the computer from being used. On a server that uses a custom shell, you might not even be able to disk boot around it. Thus, it is a form of malware.
