Version 2013
-------------------
System requirements
-------------------
AVG Anti-Virus for Linux/FreeBSD requires system with following or
newer library:
- libc.so.6 (Linux)
- libc.so.7 (FreeBSD RELEASE-7.3)
For RELEASE-8 and CURRENT the compat7x port located in /usr/ports/misc is
needed.
- libiconv.so.3 (FreeBSD)
- for amd64 architecture the lib32 compat libraries are needed
For on-access scanning feature either redirfs, dazuko or dazukofs is needed.
Please follow the avgoad(1) man page for more detail description.
Minimum hardware requirements:
- CPU: i686 or amd64 on 800 MHz
- Mem: 512 MB, 1GB is recommended
- HDD: 500 MB of free space
Installation
------------
Download latest rpm, deb, sh or tar.gz package from http://free.avg.com/us-en/download.prd-alf and
follow these steps:
* Installation from RPM (Linux only)
# rpm -i avg2013lms-r{release}-a{vdb version}.{architecture}.rpm
* Installation from .deb (Linux only)
# dpkg -i avg2013lms-r{release}-a{vdb version}.{architecture}.deb
* Installation from sh
# chmod +x avg2013lms-r{release}-a{vdb version}.{architecture}.sh
# ./avg2013lms-r{release}-a{vdb version}.{architecture}.sh
* Installation from .tar.gz
# tar xzvf avg2013{edition}-r{release}-a{vdb version}.{architecture}.tar.gz
# cd avg2013{edition}-r{release}-a{vdb version}.{architecture}
# ./install.sh
where:
- edition substitutes 'lms' for the Linux version and 'fms' for the FreeBSD version
- release substitutes the build number
- vdb version substitutes virus database version
- architecture substitutes the target cpu architecture
It is recommended to run 'avgsetup' helper tool after the installation.
Running AVG
-----------
For any action to be performed within AVG system, such as updating, scanning,
e-mail server functionality or on-access server functionality, so called AVG
daemons have to be running.
AVG daemons are launched automatically on system boot by init script. Later,
they can be controlled either by init script or by special avgctl command line
tool.
1) Usage of init script on Linux / FreeBSD.
* Linux
# /etc/init.d/avgd {start|stop|status|restart|condrestart}
* FreeBSD
# /usr/local/etc/rc.d/avgd.sh {start|stop|status|restart|condrestart}
2) Usage of avgctl command line tool
# avgctl --start[=component] Starts AVG or specified component.
# avgctl --stop[=component] Stops AVG or specified component.
# avgctl --stat[=component] Shows statistics of AVG or specified component.
# avgctl --restart[=component] Restarts AVG or specified component.
# avgctl --reset=component Resets statistics of specified component.
For more detailed information please refer to the respective man page or avgctl help.
Description
-----------
Avg functions are secured by several daemons that are managed via command-line.
DAEMONS:
avgd -- general AVG daemon; starts first, manages other AVG daemons
avgavid -- AVI daemon; loads AVI into shared memory
avgsched -- scheduler for planning periodic events (update etc.)
avgtcpd -- e-mail scanning daemon; supports SMTP, AVG, and Milter protocol
avgspamd -- anti-spam daemon
avgscand -- anti-virus daemon
avgupd -- update daemon
avgoad -- on-access daemon
COMMAND-LINES:
avgctl -- basic control of AVG product, such as launching, stopping,
restarting, and getting statistics from running daemons
avgcfgctl -- can get and set configurations values
avgscan -- launch on-demand scan of requested path
avgupdate -- run virus database update or program update via avgupd with
specified parameters
avgvvctl -- AVG virus vault control utility
avgdiag -- tool for sending problem reports to crash analysis portal
avgevtlog -- tool for reading/managing AVG event log
avgsetup -- helper tool for basic integration with mail/file server
For more detailed information please refer to the respective man page.

If on-demand scan is running:
/bin/login --

Diagnostic and system report
----------------------------
In case of troubles with any AVG Technologies product, gathering of specific
data is being performed by the avgdiag utility.
When sending data manually, it is very important to attach a detailed
description of this particular problem and to specify it with "-d, --dsc=
switches. It is also good to make sure that AVG customer support assigns a
specific ID to your report, which eventually facilitates its identification
(this is being defined by "-i, --id=
Automatic reporting of AVG processes crashes is turned off by default; if you
want to enable this function, please add AVG_DIAG option to your
/opt/avg/av/cfg/dump.ini file. For example:
"actions = GDB_DUMP CRASH INFO AVG_DIAG"
This configuration ensures that should any AVG process crash, an adequate report
will be immediately sent to AVG Technologies.
For more detailed information please refer to the man page of avgdump, avgdiag
help or /opt/avg/av/doc/README.avgdiag document.
