Lookout Mobile Security
While VirusBarrier is the only AV tool for iOS, Lookout is available on iOS, but this version doesn’t scan for viruses. It does back up your contacts and let you locate a missing iPhone over the Internet. It will show you on a map, using your phone’s GPS, where the device is. Also, Lookout will warn you if you are connected to an unsecured Wi-Fi network. It will alert you to out-of-date software and to iOS updates that haven’t yet been installed, and it will tell you if an app is trying to track your location.
Available on Android too? Yes
