ClamAV on Dapper

Update 2009-07-03: Install development libraries for ncurses to make clamdtop work. See below.
Update 2008-04-30: Change compiler for 0.93, see below.
The newest clamav is not always obtainable as .deb, so this is what I did:

• Install some needed stuff:
  apt-get install libgmp3-dev libbz2-dev
• Create the clamav user and group:
  adduser --system --home /dev/null --group clamav
• make directories if you need them:
  mkdir /var/log/clamav; chown clamav /var/log/clamav
  mkdir /var/run/clamav; chown clamav /var/run/clamav
  mkdir /var/lib/clamav; chown clamav /var/lib/clamav
  
• Download the source from www.clamav.net
• untar (with 'tar zxvf')
• cd into the source directory
• ./configure --prefix=/usr --sysconfdir=/etc/clamav
• make; make check; make install
• clamd -V

• Update for version 0.93.
  Trying to compile version 0.93, raises the following error:
  checking for gcc bug PR28045... configure: error: your compiler has gcc PR28045 bug, use a different compiler, see http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28045
  There is is some explanation here.
  Recommend is to use an older compiler. Just do this:
  apt-get install gcc-3.4
  To switch from gcc-4.0 to 3.4, use this script:
  #!/bin/bash
  # uses gcc-3.4
  cd /usr/bin
  rm gcc
  ln -s gcc-3.4 gcc
  rm gccbug
  ln -s gccbug-3.4 gccbug
  rm gcov
  ln -s gcov-3.4 gcov
  And vice versa:
  #!/bin/bash
  # uses gcc-4.0
  rm gcc
  ln -s gcc-4.0 gcc
  rm gccbug
  ln -s gccbug-4.0 gccbug
  rm gcov
  ln -s gcov-4.0 gcov
  end update for 0.93
• Update for version 0.95.x
  The same gcc problems. But there's a new tool: clamdtop. It needs ncursus. So do this before ./configure:
  apt-get install libncurses5-dev
  end update for 0.95.x
• You need to obtain an /etc/init.d script. I used the one that was installed with the standard dapper clamav package, and then changed some pathnames. After you installed an /etc/init.d script, do
  update-rc.d clamav-daemon defaults
  update-rc.d clamav-freshclam defaults

AFAIK your old config files in /etc/clamav will not be overwritten. However, it's a good idea to make a copy of those before you install clamav.

The old (pre-90) config files are not compatible. You need to edit them.

In clamd.conf, you add 'yes' to all options that have no argument. For example: in the old config file, it says:

In freshclam.conf, you need to change

now restart both deamons:

Check the logfiles!
