Which action can help make your computer resistant to online attacks?

Installing antivirus software is a fundamental action that can significantly enhance your computer's resistance to online attacks. Antivirus software is designed to detect, prevent, and remove malicious software (malware) including viruses, worms, and trojan horses. It continuously scans your system for potential threats and provides real-time protection by monitoring incoming and outgoing files and data.

Antivirus solutions also include features like automatic updates to ensure they are equipped with the latest threat definitions and security measures. This is crucial as cyber threats continuously evolve, and having the latest protections is necessary for maintaining a strong defense against emerging vulnerabilities and attacks. By using such software, users can mitigate the risk of infections and safeguard personal data, making their system more resilient against a range of online threats.

In contrast, disabling the firewall can expose your computer to numerous vulnerabilities, while using public Wi-Fi can lead to unauthorized access and data theft if proper security measures are not in place. Additionally, turning off automatic updates can leave your system outdated and susceptible to exploits, as security patches and improvements often come through these updates.
