Most modern antivirus software solutions come with automatic updates enabled by default. Automatic updates are designed to ensure that your antivirus definitions stay up to date without requiring manual intervention. The software periodically checks for new updates from the vendor's servers and downloads and installs them silently in the background.

To ensure that automatic updates are enabled, open your antivirus software's settings and look for the update or update schedule options. Enable any features related to automatic updates, and adjust the frequency if possible. It's recommended to keep automatic updates enabled to stay protected against new threats as soon as they emerge.

However, it's essential to check periodically if the automatic updates are functioning correctly. Some factors, such as internet connectivity issues or firewall settings, may prevent your antivirus software from receiving updates. Verifying that your software is up to date gives you an extra layer of assurance.
