Which of the following is not considered a best practice for configuring a virus scanner?

Monthly removal and re-installation of the virus scanner is not considered a best practice for configuring a virus scanner. This approach does not contribute to effective security management; instead, it disrupts the consistent operation of the antivirus software and may leave the system vulnerable during periods when the scanner is uninstalled. Regular updates and maintenance of the antivirus software are essential to ensure that it can detect and respond to the latest threats, but simply removing and reinstalling it on a monthly basis is inefficient and counterproductive.

In contrast, performing complete scans of all files weekly helps maintain a thorough check for malware that may have gone unnoticed day-to-day. Automatic updates several times a day are crucial for ensuring that the virus definitions are up-to-date, which is essential for defending against the newest threats. Scanning programs as they are executed provides immediate feedback and protection by allowing the scanner to detect and neutralize threats as they arise, which is a proactive security measure.
