Why is it necessary to keep antivirus definition files updated?

Answer and explanation

Correct answer: To identify new threats

Antivirus definition files contain detection information, often called signatures or rules, for recognising malicious files and behaviours. Threats change constantly, so updates help the antivirus identify newer malware that an old database may miss. Option B is correct. Updating definitions does not alter screen colour, storage capacity, or mouse speed.
