Which of the following is a technique used to prevent malware infections?

Keeping software up to date is a critical technique used to prevent malware infections. When software developers release updates, they often include patches that address known security vulnerabilities which malicious actors could exploit. By ensuring that all applications, operating systems, and security programs are regularly updated, users minimize their exposure to vulnerabilities that could be targeted by malware. Regular updates also enhance the overall security measures in place, making systems less attractive targets for attackers.

Using weak passwords, disabling firewall settings, and ignoring security warnings all represent actions that can significantly increase the risk of malware infections, as they reduce the protective barriers that software and security settings provide against potential threats.
