Wednesday “Good Morning America” and Internet safety expert Parry Aftab of WiredSafety.com brought parents and kids together to discuss a new, possibly dangerous phenomenon called “sexting” – teens sharing with friends sexually explicit images or messages via cell phones. We asked viewers to send in their questions about how to protect their kids, and the response was overwhelming. So we brought Aftab back to respond to some of the most common, most pressing questions we received.

What were those three things parents can do to see if their kids are at risk?

First, parents should Google their child’s first and last names in quotes, Aftab said. Second, do the same with their child’s cell phone number. See what results come back for each of these searches.

Third, parents can download Google Desktop, which can search your computer for pictures and videos the same way regular Google searches the Internet. That way you can see if your computer is already home to some potentially dangerous images or videos. To find Google Desktop, do a search for “Google Desktop” on Google.com.  READ MORE & SEE VIDEO
