“Guardly” for Android, Apple and Blackberry phones guards you. If you think you’re being attacked, tap the app, as they say, and it blasts out a siren warning.

Hotel and library computers are easy to compromise. In short, they’re generally not safe from hackers wanting to steal your information or your identity.
