What is the best practice regarding antivirus software on personal computers?

Using legitimate, known antivirus software is a crucial best practice for maintaining the security of personal computers. This type of software is designed to detect, prevent, and remove malicious software (malware) that could compromise the system's integrity and security. Legitimate antivirus programs are regularly updated by their manufacturers to provide the best protection against the latest threats. They offer features such as real-time scanning, scheduled updates, and the ability to remove or quarantine infected files.

On the other hand, utilizing administration accounts for all users can lead to security vulnerabilities, as this may give unauthorized users access to sensitive system settings. Declining security updates leaves the system exposed to new vulnerabilities that can be exploited by malware. Disabling password features significantly weakens security by allowing unauthorized access to the computer. Overall, using reputable antivirus software greatly enhances the security posture of a personal computer by providing essential layers of protection against various cyber threats.
