Which of the following is included in actions to help avoid viruses?

Regularly updating software is a key action in helping to avoid viruses. Software developers frequently release updates not only to introduce new features but also to address security vulnerabilities that could be exploited by malicious software. By keeping software up-to-date, users ensure that they have the latest patches and security enhancements, significantly reducing the risk of infection from viruses and other malware.

In contrast, sharing passwords poses a risk by exposing personal and sensitive information, while disabling antivirus systems removes a critical layer of protection against malicious threats. Additionally, using public Wi-Fi without precautions can lead to various security issues, as such networks are often less secure and can be targeted by attackers seeking to compromise devices connected to them. Therefore, maintaining updated software is a proactive step that helps safeguard against potential threats.
