Malicious software (malware) can harm devices by slowing them down, causing data loss, gaining unauthorized access to sensitive information, or completely failing systems. Protective measures like antivirus software, firewalls, regular updates, and safe browsing habits are essential to mitigate malware risks. Common types of malware include viruses, Trojans, worms, adware, spyware, ransomware, botnets, keyloggers, and those spread through drive-by attacks. Users should take precautions like installing antivirus software, updating regularly, using strong unique passwords, enabling firewalls and two-factor authentication, avoiding public Wi-Fi for sensitive activities, limiting administrative privileges, and backing up data.
