Need app to lock down other apps, must be pw protected itself

I installed Smart Applock (free) on my Droid 3, but I've discovered that it can be quit in the Task Manager. The Play Store page for the paid version doesn't mention if it's protected itself. Is there a suggestion of an app that password protects other apps' use and also is protected against being just dumped, rendering it basically useless?

Thanks.
