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 scan engine. To carry out regular updates, the

Updater component is integrated into your AntiVir. The Updater ensures that your

AntiVir program 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 which

are used by your AntiVir program to scan for viruses and malware and repair

infected objects.

–

Scan engine:

The scan engine contains the methods used by your AntiVir program 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 scan 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 scan engine are updated, the computer does not have to be

restarted.
Note

For security reasons, the Updater checks whether the Windows hosts file of your

computer was altered, whether the Update URL, for example, was manipulated by

malware and is diverting the Updater to unwanted download sites. If the Windows hosts
file has been manipulated, this is shown in the Updater report file.
An update is automatically performed 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

performed 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 programs on more than one computer in a network. A download server on an

intranet can be used to ensure AntiVir programs are 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 that is compatible with the update structure of your AntiVir

program.
