According to a study, conducted by Symantec Corp, computer security company, children are increasingly using the Internet to watch YouTube videos, connect with friends on social network sites and look up "sex" and "porn”.

Symantec identified the top 100 Web searches conducted between February and July through its family safety service OnlineFamily.Norton, which monitors children's and teenager's Internet use. 

The list was compiled after Symantec considered 3.5 million searches made by the OnlineFamily.Norton which lets parents see what children are searching for and who they are talking to on instant messaging and what social networks they are using.

Thus, it was unveiled that the most popular search term was for YouTube, with Internet star, Fred Figglehorn, a fictional character whose YouTube videos are popular with children, coming 9th in the top searches.

Google appeared to become the second most popular search term, while Yahoo came seventh, while social network site Facebook ranked third and MySpace came fifth in the list. But the words "sex" and "porn" also made them into the top 10, ranked numbers four and six, respectively.

Michael Jackson, eBay, Wikipedia, Miley Cyrus who plays Hannah Montana in the hit Disney series, Taylor Swift, Webkinz, Club Penguin, and the Black Eyed Peas' song "Boom Boom Pow are among the other popular search terms.
