Have you checked with your daughter the last time she ran Pest Patrol?
The problem is, and it is well known to other forum members, that Pest Patrol (and it's AOL clone) will always delete Limewire.exe (and/or LimewireWin.exe) whenever you run it.
These are some of the past postings and solutions to Pest Patrol and it's replicas.
