As far as I know, the ctrl alt del screen shows every process running, even system processes. What you can do however, is make a teeter-totter application: make two progs, both doing exactly the same, start each other, and keep starting each other when they get terminated. Almost impossible to terminate. If you're going for stealth, I fear I can't help you.
You can hide and show your forms though, with the me.hide and me.show code's, or with me.visible = false, and me.visible = true.
Hope to have helped you
