Cyber bullying is increasing as more teenagers use social media. Being bullied online affects children's well-being and can cause them to avoid school or social activities. Potential solutions include making social media sites require minimum ages and adding reporting functions. Virus infections are a threat as computers can get viruses from emails or unsafe websites, allowing hackers to access and delete private files. Spam emails also spread viruses by tricking recipients into clicking malicious links. Phishing scams trick people into entering private details like bank account information on fake websites. Denial of service attacks aim to make networks or machines unavailable to intended users by overloading them. Strengthening security could help address these cyber threats.
