Deleting the Task Manager

Today we really got into malware and hacked a couple of computers in different ways. I started out by adding something on a computer and then using another computer went to a ip webpage that allowed me to view processes, see system stats, and more. In addition I was able to delete or execute almost all programs on the machine. Next I created my own virus can could do several different things, even change into a worm to infect the computer. Today I did a bunch of things that was highly illegal. Well that is, if I do it outside this classroom.
