Stefano!
I've done what you told me.
1) The command:
rpm -qa | grep clam
returned nothing.
2) I've ran the antivirus_install.sh maybe 30 min ago, and the server returns
Installing ClamAntiVirus on SME Server 6.0 ....
A lot of time, no?
3) I'll be waiting more, but I have a doubt: the installer (antivirus_install.sh) insists that the file is an upgrade so it needs to have a previous version installed on the server... and we have uninstalled it by using the command rpm...
Could this causes problems?
Thanks again.
