Increasing child exposure to unsuitable web material has affected nearly 60 pct of Brit kids - a finding that further fuels concerns over how safe the internet actually is.
National Society for the Prevention of Cruelty to Children (NSPCC) urges that new computers should carry high-security "blocking" software that stop them from viewing violent or sexually explicit pictures.
The recommendation came after a child posted a comment on the message board of the NSPCC's website There4me.com saying: "I've seen violent images I didn't search for. I was freaked out."
"We are alarmed by how easy it is for children to access disturbing internet material," the Sun quoted Policy adviser Zoe Hilton, as saying.
"High-security parental controls in computers would help shield them.
"We also want retailers to ensure computers have protection software before they are sold to parents," Hilton added.
