No need to, this was resolved in newer versions. You simply need to upgrade your \
version of ClamAV.

For Debian I suggest adding etch volatile source to /etc/apt/sources.list

deb http://volatile.debian.org/debian-volatile etch/volatile main

Then:

gpg --keyserver subkeys.pgp.net --recv-key BBE55AB3
gpg --armor --export BBE55AB3 | apt-key add -

apt-get update

apt-get install clamav clamav-daemon clamav-freshclam

At least, this is how I would do it. YMMV. No guarantees.

This subject is off topic.
