2) installing automatic internet updater
An automatic internet updater is available with version 2.1.1 of
AntiVir for UNIX. This is a daemon that will run in the background
and automatically check for updates (internet access is required).
You may also manually check for updates using:
antivir --update
You do not need to install the automatic internet updater in order
to manually check for updates. Please read the README file for more
information on updates and how they can best suit you.

3) installing AvGuard
Version 2.1.1 of AntiVir for UNIX is capable of on-access,
real-time scanning of files. This provides the ultimate protection
against viruses and other unwanted software. The on-access scanner
(called AvGuard) is based on Dazuko, a free software project providing
access control. In order to use AvGuard you will need to compile Dazuko
for your kernel. Please refer to src/HOWTO-Dazuko for information on how
to do this. There are several ways in which you can install AvGuard.
module - Dazuko will be loaded by the avguard script
kernel - Dazuko is always loaded
(and should not be loaded by the avguard script)
no install - do not install AvGuard at this time
Note: Dazuko currently only works with GNU/Linux and FreeBSD systems.
If you are interested in helping us port Dazuko to OpenBSD,
feel free to check out the Dazuko Project at:
http://www.dazuko.org
available options: m k n
How should AvGuard be installed? [n] m
Enter the full path to dazuko.o: /lib/modules/2.4.26/misc/dazuko.o

NumDaemons (1 of 14)
==========
Files that are accessed by multiple processes at the same time can be
scanned by AvGuard in parallel. This is accomplished by running multiple
scanning daemons, which allows your machine to run AvGuard with the least
amount of performance reduction.
A typical workstation only requires 3 daemons for optimal performance. If
you are running additional servers (such as file, http, ftp, etc) then it
is recommended that more daemons are used. You can disable AvGuard by
setting a value of 0 here.
available options: 0-20
How many daemons would you like to run? [3] 5
AccessMask(1) (2 of 14)
=============
Files may be scanned as they are opened. This is useful for preventing
users from accessing concerning files. This includes opening, reading
and copying concerning files.
available options: y n
Would you like to scan files as they are opened? [y] y
AccessMask(2) (3 of 14)
=============
Files may be scanned as they are closed. This is useful for preventing
users from creating concerning files. This includes saving, downloading
and copying concerning files.
available options: y n
Would you like to scan files as they are closed? [y] y
AccessMask(4) (4 of 14)
=============
Files may be scanned as they are executed. This is useful for preventing
users from running concerning programs.
available options: y n
Would you like to scan files as they are executed? [n] n
RepairConcerningFiles
=====================
If a concerning file is found, AvGuard can try to remove the problem. If
the problem cannot be removed, access to the file will still be blocked.
However, if the problem can be removed, the user will be allowed normal
access.
available options: y n
Would you like to try to repair concerning files? [n] n
LogOnly/Rename/MoveConcerningFilesTo (6 of 14)
====================================
When an alert is found, there are several ways in which AvGuard can
respond.
log only - the name of the concerning file will only
be logged using syslog
rename - the concerning file will be renamed to have
a .XXX extension
move - the concerning file will be moved to a
directory of your choice
Regardless of which option you choose, the event involving the concerning
file will be logged using syslog and access to the file will be blocked.
available options: l r m
How should concerning files be handled? [l] l
IncludePath (7 of 14)
===========
AvGuard gives you the option of specifying the paths from which files
will be scanned. All sub-directories of specified paths will also be
scanned as files are accessed. You must specify at least one path.
Current include paths = NONE
available options: y n
Would you like to specify new include paths? [y] y
Type in the paths one at time, pressing ENTER after each path. All paths
must be absolute (beginning with '/'). When you are finished, simply
enter a blank line.
[IncludePath 1] /home
[IncludePath 2]
ExcludePath (8 of 14)
===========
Unless under the specified included paths, files will not be scanned.
You may also want that particular sub-directories within the included
paths are also not scanned.
For example, perhaps you want the entire /home directory scanned except
for /home/bill. AvGuard allows you to specify sub-directories of the
included paths that will not be scanned. These sub-directories are called
exclude paths. In this example /home/bill would be an exclude path.
Current exclude paths = NONE
available options: y n
Would you like to specify new exclude paths? [n] y
[ExcludePath 1] /home/adm
[ExcludePath 2] /home/www
[ExcludePath 3]
ArchiveScan (9 of 14)
===========
There may be alerts hiding within compressed files (.zip, .gz, .tar, etc).
You may configure AvGuard so that these compressed files are decompressed
and searched for concerning files. This will help to ensure that your server
is free from unwanted files.
available options: y n
Would you like to scan compressed files? [n] y
ArchiveMaxSize (9-2 of 14)
==============
In order to scan the contents of compressed files, the files must be
decompressed. For very large compressed files it could take a long time
to decompress everything. For this reason, you may wish you put a size
limit for compressed files that will be scanned. The size limit is given
in bytes. For example, 1 gigabyte = 1073741824 bytes. You may set this
value to 0 to have no limit on the size of scanned compressed files.
available options: 0-??
What is the maximum size compressed file (in bytes)
to be scanned? [1073741824]
ArchiveMaxRecursion (9-3 of 14)
===================
It is possible that a compressed file has many compressed files as
contents. For example, inside of filename.zip there may be a file1.zip
file. Each compressed file within a compressed file is referred to as
a recursion level. If AvGuard should decompress filename.zip it must scan
recursion level 1. If it is supposed to also decompress file1.zip, it
must scan recursion level 2.
Since decompressing takes extra time, you may wish to set a limit on
the recursion level that will be scanned. A value of 0 means that there
will be no limit.
available options: 0-??
What is the maximum recursion level in compressed files
to be scanned? [5]
ArchiveMaxRatio (9-4 of 14)
===============
Compressed files are usually smaller than the original files. The amount
that the files are reduced in size is called the compression ratio. If
an archive has a compression ratio of 5, this means that the decompressed
contents of the archive take up 5 times the amount of space as the archive.
It is possible that a compressed file has many compressed files as
Sometimes the compression ratio for files can be very large. These types
of files can cause an enormous strain on system resources if they are
decompressed. For this reason, you may will to set a limit on the
compression ratio. A value of 0 means that there will be no limit.
available options: 0-??
What is the maximum allowed ratio for compressed files
to be scanned? [150]

AutoUpdateEvery2Hours/AutoUpdateDaily (10 of 14)
=====================================
AntiVir is equipped with an Automatic Internet Updater. At specified
intervals, AntiVir will connect to an updater server to check for newer
versions of the AntiVir engine or the data files. If a newer
version is available, AntiVir will automatically download and install
the updates without requiring any special attention. This allows AntiVir
to be kept current against attacks and problems.
AntiVir can be configured to check for updates every 2 hours (2) or
once a day (d). You can also choose to have the Automatic Internet
Updater never check (n).
available options: 2 d n
How often should AntiVir check for updates? [n] n

the information to log: facility and priority. Facility specifies the
type of program making the log entry. Priority specifies the importance
of the log entry.
If you are unfamiliar with syslog then you may simply accept the default
values. However, it is encouraged that you learn about syslog since it
is used by many services to log important events.
