Some user kept on browsing sites he wasn't supposed to. I was asked to uninstall IE, but that was not possible on that OS, so I just wrote a small script to keep the browser closed at all times.

<file autoit KillIE.au3>
; Remove tray icon
TraySetState(2)
 
; Loop diz' biatch. KILL, KILL, KILL!
While 1
	ProcessClose("iexplore.exe")
	Sleep(1000)
WEnd
</file>
