Avira AntiVir on Ubuntu

Avira seems to be better at detecting Windows viruses than ClamAV, as I experienced today scanning the same USB device on 2 machines. Avira (in Windows) spotting 6 worms vs. ClamAv's 1 detection.

So I decided to give Avira in Ubuntu a shot.
System snapshot info:
Ubuntu 9.04
Kernel Linux 2.6.28-15-generic
GNOME 2.26.1

Here's how I got it to work:
1. Download the Linux Avira Antivir installer here: http://www.free-av.de/en/download/download_servers.php
My downloaded copy was antivir_workstation-pers.tar.gz

2. In a terminal window, execute:
tar -xvf antivir_workstation-pers.tar.gz
This created a folder named antivir-workstation-pers-3.0.5-11 in my download folder.

3. Still in the terminal window, cd to the created folder and type:
sudo ./install

4. Follow the prompts (I just based on common sense). Link references:

• Detailed, but a bit old (2006)
• Avira forum thread 1 (2009 - telling that Dazuko is included in the installer already)
  
• Avira forum thread 2 (2009 - just shows the command how to update signatures)
• Avira forum thread 3 (2008 - older, just to see how well the Avira team simplified installation since)

There's no GUI! A minor hassle, though. It will install in the /usr/lib/AntiVir folder.

Terminal commands learned:
To update the engine & signatures:
sudo avupdate --product=Guard
To scan a USB drive:
sudo avscan /media/disk
