AVG Anti-Virus for Linux/FreeBSDVersion 2013
================================
System requirements
-------------------
AVG Anti-Virus for Linux/FreeBSD requires system with following ornewer 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 isneeded.
- libiconv.so.3 (FreeBSD)
- for amd64 architecture the lib32 compat libraries are neededFor 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://www.avg.cz/linux and
follow these steps:
* Installation from RPM (Linux only)
# rpm -i avg2013flx-r{release}-a{vdb version}.{architecture}.rpm* Installation from .deb (Linux only)
# dpkg -i avg2013flx-r{release}-a{vdb version}.{architecture}.deb* Installation from sh
# chmod +x avg2013flx-r{release}-a{vdb version}.{architecture}.sh# ./avg2013flx-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.shwhere:
- edition substitutes 'flx' for the Linux version and 'ffb' 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 linetool.
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 serverFor more detailed information please refer to the respective man page.
AVG process tree (might look different in your configuration):
/opt/avg/av/bin//avgd
\--- /opt/avg/av/bin/avgavid
\--- /opt/avg/av/bin/avgtcpd
| \--- /opt/avg/av/bin/avgscand -c 3
\--- /opt/avg/av/bin/avgspamd
\--- /opt/avg/av/bin/avgoad
| \--- /opt/avg/av/bin/avgscand -c 4
\--- /opt/avg/av/bin/avgsched
If update is running:
\--- /opt/avg/av/bin/avgupd
/bin/login --
\--- -bash
\--- /opt/avg/av/bin/avgupdate
If on-demand scan is running:
/bin/login --
\--- -bash
\--- /opt/avg/av/bin/avgscan /
\--- /opt/avg/av/bin/avgscand -c 10
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=<file>"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=<id>" switches).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 reportwill 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.

AVG ANTIVIRUS FREE - FOR LINUX 的掃描速率非常之快，消耗的資源也比較少。至於查殺能力如何呢，暫時還沒有看到權威的評測的資料。暫時不能做過多評論。
在上篇文章“記一次Linux伺服器上查殺木馬經歷”裡面，我介紹了使用ClamAV清理了木馬程式，當時以為清理乾淨了，但是過了一天後，使用NetHogs又發現可疑程式。使用ClamAV查殺清理又發現感染了Linux.BackDoor.Gates，查殺完成後，重啟系統後到目前為止沒有發現任何異常情況。後來我在這臺Linux伺服器安裝了AVG Anti-Virus，掃描倒是非常快，比ClamAV的速度要快出幾個等級，但是查殺能力無法驗證。倒是掃出了很多Linux.BackDoor.Gates建立的一些連結。ClamAV倒是沒有掃出這些。
[root@LNX17 ~]# ls -lrt /etc/rc.d/rc5.d/S97DbSecurityMdt lrwxrwxrwx. 1 root root 25 Jul 17 08:28 /etc/rc.d/rc5.d/S97DbSecurityMdt -> /etc/init.d/DbSecurityMdt
[root@LNX17 ~]# ls -lrt /etc/init.d/DbSecurityMdtls: cannot access /etc/init.d/DbSecurityMdt: No such file or directory
[root@LNX17 ~]#
清理這些連結後，已經過了幾天，再也沒有發現異常情況，從網路發包、收包情況看，已經沒有任何異常情況。

rm -f /etc/rc.d/rc2.d/S97DbSecurityMdt
rm -f /etc/rc.d/rc2.d/S99selinux
關於這臺伺服器是如何掛馬的呢？ 我也在思考，奈何能力有限，無法確認一些猜測（個人猜測是利用Tomcat漏洞掛馬）。關於Linux安全管理方面，個人覺得防毒軟體只是根治病毒木馬的一種手段。我們需要從很多方面（安全補丁更新、正確配置、防火牆配置……）去預防、監控才能真正的確保系統的安全。
