Internet threats refer to various dangers that can harm users or their devices while online. These threats include malware, which is malicious software designed to damage or disrupt systems, and phishing attacks, where scammers trick individuals into revealing personal information. Other threats include ransomware, which locks users out of their files until a ransom is paid, and denial-of-service attacks, which overwhelm websites to make them unavailable. To protect against these threats, users should employ strong passwords, keep software updated, and use security tools like antivirus programs. Awareness of potential risks, such as suspicious emails or links, is crucial for safe internet browsing.
