70 percent of teenagers hid their online behavior from parents, a new study shows

A new study by McAfee is showing what teenagers are really doing online and the results are a bit scary. An incredible 70 percent of teenagers in the study say they hid at least part of their online activity and behavior from their parents. What they are hiding could be even more shocking, especially if you are a parent.

43 percent of the surveyed teens accessed some form of simulated violence while surfing the web, and likely more worrying for parents is the fact that 32 percent view nude content or pornography on the internet. Even worse yet is that half of the parents believe that their children are telling them everything they are doing online.

"While it is not necessarily surprising that teens are engaging in the same types of rebellious behaviors online that they exhibit offline, it is surprising how disconnected their parents are," Stanley Holditch, Online Safety Expert for McAfee, said today in a statement. "There is a major increase in the number of teens finding ways to hide what they do online from their parents, as compared to the 2010 study."

The study also found that 15 percent of teens had hacked a social networking account and 9 percent have hacked into another's e-mail account. 31 percent have pirated a movie or music. How are these kids covering their tracks? 53 percent say they clear their browser history and 46 percent minimize their screens when parents walk by. About a quarter admit to lying or omitting details about online activity.
