Hi,

 under debian edge there is a bug in clamav so that it produces 100% cpu load and can´t open a unix socket.

Like this: 

connect to UNIX socket /var/run/clamav/clamd.ctl: No such file or directory

You have to update the clamav to solve this problem. Add folowing package sources in sources.list

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

 then do: apt-get update

and install the packages: 

clamav-daemon
clamav-freshclam
clamav-base
clamav

then it sould work.

Good Luck
