How can one protect their computer from malware?

Installing antivirus software, keeping systems updated, and avoiding suspicious downloads is a comprehensive strategy for protecting a computer from malware.

Antivirus software plays a critical role in detecting and neutralizing malware threats before they can compromise the system. Regular updates are essential because they ensure the software is equipped with the latest malware definitions and security patches, addressing newly discovered vulnerabilities. Additionally, avoiding suspicious downloads is crucial, as many malware attacks originate from unverified sources or deceptive links. This proactive approach creates multiple layers of security, significantly reducing the risk of infection by malicious software.

Regularly backing up files, while important for data recovery, does not prevent malware from accessing the system or infecting files. Using public Wi-Fi networks frequently increases exposure to security risks, as these often lack proper encryption, making it easier for attackers to intercept data. Deleting downloaded files immediately does not provide a preventative measure against malware; the risk lies in how files are handled before deletion. Overall, the correct answer emphasizes both preventative measures and active protection against malware.
