how to get rid of error messages.

I have a school mac. it has admin controls. if you push command+esc, it tries to launch front row, and because it is an admin app only, it launches an error. people troll each other with it because it keeps popping back up, and the only way to get rid of it is to sign out. I want of know if there is a way, using terminal, to get rid of this error message? I already tried using the killall - KILL Front Row command on terminal. What is the app that launches the errors called. is it just Finder?

G'day and welcome to the forums.

This is a school computer so leave it be and no mucking about in Terminal. Pretty powerful black magic in the hands of the unskilled.
