7 Updates
The effectiveness of anti-virus software depends on how up-to-date the program is, in
particular the virus definition file and the search engine. To carry out updates, the
Updater component is integrated into AntiVir Professional. The Updater ensures that
Avira AntiVir Professional is always up-to-date and able to deal with the new viruses that
appear every day. Updater updates the following components:
– Virus definition file:
The virus definition file contains the virus patterns of the harmful programs used by
AntiVir Professional to scan for viruses and malware and repair infected objects.
– Search engine:
The search engine contains the methods used by AntiVir Professional to scan for
viruses and malware.
– Program files (product update):
Update packages for product updates make extra functions available to the
individual program components.
An update checks whether the virus definition file and search engine are up-to-date and
if necessary implements an update. Depending on the settings in the configuration, the
Updater also carries out a product update or informs you of the product updates
available. After a product update, you may have to restart your computer system. If only
the virus definition file and search engine are updated, the computer does not have to be
restarted.
Note
For security reasons, the Updater checks whether the Windows host file of your
computer was altered to the effect that, for example, the Avira AntiVir Professional
update URL was manipulated by malware and diverts the Updater to unwanted
download sites. If the Windows host file has been manipulated, this is shown in the
Updater report file.
AntiVir Professional is automatically updated in the following interval: 60 minutes. You
can edit or disable the automatic update through the configuration
(Configuration::Update).
In the Control Center under Scheduler, you can create additional update jobs that are
carried out by Updater at the specified intervals. You also have the option to start an
update manually:
– In the Control Center: in the Update menu and in the Status section
– via the context menu of the tray icon
Updates can be obtained from the Internet via a proprietary web server or via a web or
file server on an intranet which downloads the update files from the Internet and makes
them available to other computers on the network. This is useful if you want to update
AntiVir Professional on multiple computers on a network. A download server on an
intranet can be used to ensure AntiVir Professional is up-to-date on the protected
computers using a minimum of resources. To set up a functioning download server on an
intranet, you need a server which is compatible with the update structure of AntiVir
Professional.
