The virus definition file contains the virus patterns of the harmful programs used by AntiVir Premium to scan for viruses and malware and repair infected objects.
The search engine contains the methods used by AntiVir Premium to scan for viruses and malware.
Program files (product update):
Update packages for product updates make extra functions available to the individual program components.

Depending on the settings in the configuration, AntiVir Updater also carries out a product update or informs you of the product updates available. After an update AntiVir Premium does not have to be restarted.

If the Windows host file has been manipulated, this is shown in the Avira AntiVir Premium Updater report file.
