I have just removed DrWeb from Plesk and installed the RPM's for ClamAV db then RPM's for ClamAV.

When I run the command # 'service clamav start' I get error 'clamav: unrecognized service'

Anyone any ideas how to get clamAV running.

Running Plesk 7.5.4 on RedHat Enterprise 4

Try service clamd start

Tried That, the same...
clamd: unrecognized service

HINT! Have you tried asking on the Plesk forums?

see if it created an init script...

/etc/init.d/clamav start

also... make sure it installed properly...

rpm -qa | grep clam

Clam requires a bit of tweaking because of the Plesk/Qmail set up Jonathan.

You may want to check out this walk-thru. It's always worked like a charm for me. Or I believe Scott has some Clam rpms in his [url=http://www.atomicrocketturtle.com]ART repositories as well.

Tried what you suggested above,

[root@srv01]# /etc/init.d/clamav start
-bash: /etc/init.d/clamav: No such file or directory

[root@srv01]# rpm -qa | grep clam
clamav-db-0.88-1.rhel4.art
clamav-0.88-1.rhel4.art

When the RPMs were installed the files are in a log.d directory, is this the correct directory?

/etc/log.d/conf/logfiles/clam-update.conf
/etc/log.d/conf/services/clamav-milter.conf
/etc/log.d/conf/services/clam-update.conf
/etc/log.d/conf/services/clamav.conf
/etc/log.d/scripts/services/clamav
/etc/log.d/scripts/services/clam-update
