LICENSING
---------

You must have a license file in order to use avast for linux. The license comes
in a form of a file called 'license.avastlic'. Please contact the AVAST sales
department to obtain the license.

After obtaining the license file, copy it into the /etc/avast directory:

  $ sudo cp /path/to/license.avastlic /etc/avast

In case you have been provided with an activation code, use the avastlic(1) tool
to download the license. Please note that for some codes this can only be
done limited number of times. Also, some activation codes require a customer
information to be entered and as such the tool is by default interactive
when the activation code mandates this information:

  $ avastlic -f new_license_file_path -c avast_activation_code
  $ sudo cp new_license_file_path /etc/avast/license.avastlic

In case the downloaded license is valid for multiple machines, it is recommended
to download the license once and then distribute the license file to all the
other machines.

UPDATING THE VIRUS DEFINITIONS
------------------------------

Regularly updating the virus definitions database is necessary to keep your
antivirus protection up to date. Avast antivirus provides a shell script, which
checks for the latest virus definitions database over the Internet and takes
care of its downloading and installing. The update script is automatically
installed and periodically executed every three hours.

The update script is by default executed by systemd:
* avast-vpsupdate.service
* avast-vpsupdate.timer

Start avast-vpsupdate.service to update the virus database immediately.
Enable avast-vpsupdate.timer to let it update periodically (enabled by default).

Avast uses incremental updates, so the average update data size is less than
1 MB.
