Get ClamAV running on Mac OS X (using Homebrew)

Get ClamAV running on Mac OS X (using Homebrew)

The easiest way to get the ClamAV package is using Homebrew

$ brew install clamav

Before trying to start the clamd daemon, you'll need a copy of the ClamAV databases.

Inside /your/location/to/brew/etc/clamav, you'll see 2 files:

  1. freshclam.conf.sample
  2. clamd.conf.sample

Create copies of the samples:

$ cp freshclam.conf.sample freshclam.conf && cp clamd.conf.sample clamd.conf

Open up freshclam.conf, comment out "Example" from line 8, and make sure

DatabaseMirror database.clamav.net

is enabled. Save your changes.

Then run

$ freshclam -v

to download the ClamAV databases. The output will look something like this:

Current working dir is /usr/local/Cellar/clamav/0.98.1/share/clamav

Open up clamd.conf, and

  1. Comment: "Example" from line 8
  2. Uncomment: LocalSocket /tmp/clamd.socket from line 85
  3. Save your changes

Next, let's look for the location of clamd by running: $ brew ls clamav

You should see the following:

/your/location/to/brew/Cellar/clamav/0.99.2_1/bin/clamav-config
/your/location/to/brew/Cellar/clamav/0.99.2_1/bin/clambc
/your/location/to/brew/Cellar/clamav/0.99.2_1/bin/clamconf
/your/location/to/brew/Cellar/clamav/0.99.2_1/bin/clamdscan
/your/location/to/brew/Cellar/clamav/0.99.2_1/bin/clamdtop
/your/location/to/brew/Cellar/clamav/0.99.2_1/bin/clamscan
/your/location/to/brew/Cellar/clamav/0.99.2_1/bin/clamsubmit
/your/location/to/brew/Cellar/clamav/0.99.2_1/bin/freshclam
/your/location/to/brew/Cellar/clamav/0.99.2_1/bin/sigtool
/your/location/to/brew/Cellar/clamav/0.99.2_1/include/clamav.h
/your/location/to/brew/Cellar/clamav/0.99.2_1/lib/libclamav.7.dylib
/your/location/to/brew/Cellar/clamav/0.99.2_1/lib/libclamunrar.7.dylib
/your/location/to/brew/Cellar/clamav/0.99.2_1/lib/pkgconfig/libclamav.pc
/your/location/to/brew/Cellar/clamav/0.99.2_1/lib/ (4 other files)
/your/location/to/brew/Cellar/clamav/0.99.2_1/sbin/clamd  <------------- clamd location is here
/your/location/to/brew/Cellar/clamav/0.99.2_1/share/clamav/ (4 files)
/your/location/to/brew/Cellar/clamav/0.99.2_1/share/man/ (13 files)

To start the clamd daemon, run the following:

$ /your/location/to/brew/Cellar/clamav/0.99.2_1/sbin/clamd

You should now be able to scan a file by doing:

$ clamdscan /some/location/myfile.txt

Will this automatically start the daemon after rebooting?

hi, i have installed clamav
brew install clamav
i have config files of clamd.conf and freshclam.conf also

i am trying to start clamav service

brew services start clamav

Error: Formula clamav has not implemented #plist, #service or installed a locatable service file

Thanks for these instructions. Works pretty well.

I also want clamd to start automatically every time I restart my Mac, so I went ahead and added a service to do so in the Homebrew clamav formula and submitted a PR.

If that accept to merge it, as someone tried above, users will be able to run it as a service with brew services start clamav.

It got merged! brew services start clamav now works. Or you may want to ensure it runs as root so it can scan the whole file system and start correctly on system boot with sudo brew services start clamav.
