On The Lookout
Many antimalware tools also add or enhance a phone's existing remote services for devices that are lost or stolen. One we like is Lookout for Android and for iOS,which is free and never in your face. Once registered, Lookout automatically scans apps whenever they're updated to find viruses, spyware and other pap. It also can back up contacts, block harmful URLs, and locate, scream, lock and wipe a lost phone, and even email a pic of the thief.
