What are the two most effective ways to defend against malware?

• A. Regularly backup data and use a firewall
• B. Update software and install antivirus
• C. Monitor network traffic and restrict access
• D. Change passwords frequently and use encryption

Answer: (B)

Updating software and installing antivirus are pivotal strategies in defending against malware. Software updates frequently contain patches that address vulnerabilities found in applications and operating systems, which are common entry points for malware. Keeping software up to date minimizes the attack surface and protects systems from exploits that could otherwise be leveraged by malicious actors. Additionally, installing antivirus software plays a crucial role in identifying, quarantining, and removing malicious software. Modern antivirus solutions utilize advanced technologies such as heuristic analysis and behavior monitoring to detect not just known viruses but also suspicious behavior indicative of malware activity. Together, these practices effectively reduce the likelihood of a successful malware attack, ensuring the integrity and security of systems and data. The other methods, while useful for overall security, do not directly target the malware threat in the same way. Regular backups help in recovery after an attack, but do not prevent malware from infecting systems. A firewall can control access to a network, but it cannot identify or remove malware. Monitoring traffic and restricting access are vital components of a comprehensive security strategy, yet they do not specifically defend against malware infection. Changing passwords frequently and using encryption enhance security but do not directly prevent malware attacks.
