Protecting yourself on Wi-Fi with AVG's Tony Anscombe

Just about everyone uses W-Fi these days, whether at home or on the go. But, says Larry's guest AVG Technologies' Senior Security Analyst Tony Anscombe, public Wi-Fi networks can be very insecure, especially if there is any doubt as to whose network you're on. In this lively conversation, Tony and Larry talk about how to use Wi-Fi safety, how to employ a virtual private network (VPN) for further protection, why your cellular connection is more secure than Wi-Fi and even the dangers of people, literally, looking over your shoulder as you work.
