Keeping Your Anti-Virus Program Up to Date

Dozens of new computer viruses are discovered every week. For your anti-virus program to be effective, it must be periodically updated with information on all of the latest viruses. This information is called a virus definition, and the database of virus definitions is constantly being updated by the manufacturer of your anti-virus program.

For this reason, it's important to go online at least once a week to download the latest virus definitions, as provided by the manufacturer of your anti-virus program. Most anti-virus programs can be configured to perform this update automatically. If you do not update your anti-virus program regularly, your PC will be vulnerable to infection by new computer viruses.
