Compile ClamAV from source on Mac OS X

to shell osx mac bash unix compile antivirus clamav virus by jv on Mar 11, 2008
The following instructions for compiling & installing the ClamAV virus scanner on Mac OS X require an admin user account and Xcode. Works despite some compiler warnings. Use at your own risk!

1. disable an already installed ClamAV system

clamconf      # get your ClamAV configuration
clamconf -n
clamconf | grep DatabaseOwner

Run ClamAV from a system service agent account

to shell osx mac bash unix clamav virus account agent by jv on Feb 15, 2008
The following instructions on how to run ClamAV from a system service agent account (non-root) require an admin user account, a ClamAV setup as described here and the creation of a clamavadmin system service agent account as described here.

Use at your own risk!


First uncomment the following lines of code in the first script at http://textsnippets.com/posts/show/1405:

# create further subdirectories if necessary
...
#fi
#
#fi


Then save the file, start the script and enter the following:

You are going to create a system service agent account!

Enter first name: clamavadmin

Note: The last name is optional and defaults to "agent" if you just press <return>!
Enter last name: 

Note: The user shell is optional and defaults to "/usr/bin/false" if you just press <return>!
Enter user shell: /bin/bash

Note: The home directory is optional and defaults to "/private/var/empty" if you just press <return>!
Enter home directory: /private/var/clamavadmin

System service agent account:  clamavadmin  successfully created!
