How to disable postfix, clamav and bind server?

[Regset]

Hello! How to completely remove not necessary services, such as postfix, clamav and bind server? I remove them, but they still appear. Thanks in advance for the answer!

If you know they are "unneeded", why you already don't know to remove then?
Are you sure is really unneeded?
They are *vital* to most people here, for hosting services.

yum remove -y postfix
yum remove -y clamd clamav clamav-filesystem clamav-update clamav-lib clamav-data
yum remove -y bind bind-libs bind-libs-lite bind-export-libs bind-license bind-utils

I already did it. But after a while, these services appear again. So I ask how to delete these services completely.

I solved this problem, maybe someone will find this solution useful. We just add to /etc/yum.conf:

Code Select Expand

exclude=postfix clamav clamd bind
And these services will no longer be installed.
