Removing Dr. Web - Installing ClamAV on Debian

[fluxx]

Hello,

I am running Plesk 8.0.1 on Debian 3.1 (I am new on Debian) and want to remove Dr. Web and go to the free ClamAV. That´s what I have figured out so far:

Removing Dr. Web:
apt-get remove drweb
apt-get remove drweb-qmail

Telling Plesk the change: /opt/psa/admin/bin/packagemng

Installing ClamAV:
apt-get install mailscanner
apt-get install clamav

I didn´t try this until now, because its a productive system and I am quite sure, that this is not the whole necessary procedure.
I have also found, that on some systems the wrapper "qsheff" must also be installed and "ripMIME" to examine attachments, but I am not sure, if I have to do this on my system. I cant get this packages with apt-get.

Does anybody already moved from Dr.Web to ClamAV on Debian and can tell the procedure?

Thanks,
Michael
