Updating Virus definitions and Avast Antivirus application version
Avast Antivirus uses a database of known Virus definitions to identify malware and other threats on your PC, which is why it is important to ensure the Virus definitions are regularly updated. The application refers to the user interface and all components in Avast Antivirus. Updates to the application provide bug fixes and general improvements.
By default, Avast Antivirus is set to update the Virus definitions and application automatically whenever a new version is available. We strongly recommend you keep automatic updates enabled.
