Beware of computer hackers - e-safety

Becca's computer seems to have a life of its own. She only realises something's wrong when people at school start having a go at her about the messages she's been sending online. But the messages weren't sent by her. Besides, she was out at the shops when they were written so it can't have been her. Becca eventually confides in a school prefect who tells her hackers have lots of tricks to try and get access to your computer. She tells her the best way of beating them is to choose a password which can't be guessed and to always log off. Based on a true story, actors are used to protect the real Becca's identity.
