Quizplus · Accepted Answer

The innumerable computer virus authors around the world are constantly writing new viruses, which can be combated effectively with frequent, routine anti-virus software updates. Anti-virus software maintains a compendium of "definitions," which are the pieces of identifying information that allow the software to find and quarantine a virus. Anti-virus software packages allow users to download updated definitions over the Internet through automated scans on a set schedule, often weekly, or manually, at the user's request.
