6. Updates<br />
The effectiveness of anti-virus software depends on how up-to-date the program is, in<br />
particular the virus definition file and the scan engine. To carry out regular updates, the<br />
Updater component is integrated into your Avira product. The Updater ensures that your<br />
Avira product is always up-to-date and able to deal with the new viruses that appear every<br />
day. Updater updates the following components:<br />
� Virus definition file:<br />
The virus definition file contains the virus patterns of the harmful programs which are<br />
used by your Avira product to scan for viruses and malware and repair infected<br />
objects.<br />
� Scan engine:<br />
Updates<br />
The scan engine contains the methods used by your Avira product to scan for viruses<br />
and malware.<br />
� Program files (product update):<br />
Update packages for product updates make extra functions available to the individual<br />
program components.<br />
An update checks whether the virus definition file and scan engine are up-to-date and if<br />
necessary implements an update. Depending on the settings in the configuration, the<br />
Updater also carries out a product update or informs you of the product updates available.<br />
After a product update, you may have to restart your computer system. If only the virus<br />
definition file and scan engine are updated, the computer does not have to be restarted.<br />
Note<br />
For security reasons, the Updater checks whether the Windows hosts file of<br />
your computer was altered, whether the Update URL, for example, was<br />
manipulated by malware and is diverting the Updater to unwanted download<br />
sites. If the Windows hosts file has been manipulated, this is shown in the<br />
Updater report file.<br />
An update is automatically performed in the following interval: 60 minutes. You can edit or<br />
disable the automatic update through the configuration (Configuration > Update).<br />
In the Control Center under Scheduler, you can create additional update jobs that are<br />
performed by Updater at the specified intervals. You also have the option to start an<br />
update manually:<br />
� in the Control Center: in the Update menu and in the Status section<br />
� via the context menu of the tray icon<br />
