Cyber safety involves being aware of risks to personal information and property when using the internet and protecting oneself from computer crime. Cyberbullying is a form of bullying using electronic means such as sending threats through email, spreading rumors online or on social media, and stealing account information. Common online threats include computer viruses, Trojan horses, adware/spyware, worms, and phishing. Viruses can infect other computers and steal data while Trojan horses pretend to be harmless but infect computers. Spyware aims to gather private information without consent. To stay safe online, do not share personal information with strangers and block unknown people.
