Final answer:
Anti-virus software should be updated regularly to stay informed about new viruses and provide effective protection against them.
Step-by-step explanation:
Anti-virus software should be updated regularly so they know about new viruses that they need to look for.
Regular updates are necessary because new viruses are constantly being developed, and anti-virus software needs to be equipped with the latest virus definitions and detection capabilities to effectively protect your computer. Without regular updates, your software may not catch new threats and leave your device vulnerable to attacks.
By updating your anti-virus software, you ensure that it stays up to date with the latest security patches, bug fixes, and improvements to provide optimal protection against viruses and malware.
