<p>If you're planning to run <code>freshclam</code> or <code>clamd</code> as a service on a Linux or Unix system, you should create a service account. The following instructions assume that you will use the an account named "clamav" for both services, although you may create a different account name for each if you wish.</p>
<blockquote>
<p><em>Note</em>: <em>These instructions are mostly just for folks building & installing from source.</em> If you installed a package from your Linux/Unix distribution, it probably created the account(s) for you.</p>

<h3 id="linux--unix"><a class="header" href="#linux--unix">Linux / Unix</a></h3>
<p>As root or with <code>sudo</code>, run:</p>
<pre><code class="language-sh">groupadd clamav
useradd -g clamav -s /bin/false -c "Clam Antivirus" clamav
</code></pre>
<p>If your operating system does not have the <code>groupadd</code> and <code>useradd</code> utilities, consult a system manual. <strong>Don’t forget to lock access to the account!</strong></p>
<h3 id="macos"><a class="header" href="#macos">macOS</a></h3>
<p>Prep by identifying an unused group id (gid), and an unused user UniqueID.</p>
<p>This command will display all current group PrimaryGroupIDs:</p>
<pre><code class="language-bash">dscl . list /Groups PrimaryGroupID | tr -s ' ' | sort -n -t ' ' -k2,2

<p>This command will display all current user UniqueIDs:</p>
<pre><code class="language-bash">dscl . list /Users UniqueID | tr -s ' ' | sort -n -t ' ' -k2,2
</code></pre>
<p>Then, these commands can be used to create the <code>clamav</code> group and <code>clamav</code> user.</p>
<pre><code class="language-bash">sudo dscl . create /Groups/clamav
sudo dscl . create /Groups/clamav RealName "Clam Antivirus Group"
sudo dscl . create /Groups/clamav gid 799 # Ensure this is unique!

sudo dscl . create /Users/clamav UserShell /bin/false
sudo dscl . create /Users/clamav UniqueID 599 # Ensure this is unique!
sudo dscl . create /Users/clamav PrimaryGroupID 799 # Must match the above gid!

<p>At present, the behavior differs slightly between <code>clamd</code> and <code>freshclam</code>. When run as root:</p>
<ul>
<li>
<p><code>freshclam</code> will always switch to run as the "DatabaseOwner" user account. The default account name is "clamav", or may be customized by specifying the "DatabaseOwner" setting in <code>freshclam.conf</code>.</p>
</li>
<li>
<p><code>clamd</code> will only switch to run as the "User" user account if the "User" setting is specified in <code>clamd.conf</code>. If you do not specify a "User" in the config, <code>clamd</code> will continue to run as the root user! We may change this behavior in a future version to prevent <code>clamd</code> from being run as root.</p>
</li>
</ul>
<blockquote>
<p><em>Caution</em>: We do not recommend running <code>clamd</code> as root for safety reasons because ClamAV scans untrusted files that may be <em>malware</em>. Always configure the "User" setting in <code>clamd.conf</code> if you plan to run <code>clamd</code> as a service.</p>
</blockquote>
<p>On Unix/Linux systems, <code>freshclam</code> and <code>clamd</code> will switch to run as a different user if you start them as the root user, or using <code>sudo</code>. By default, that user account is named "clamav". The purpose is t</p>
<p>If you are running <code>freshclam</code> and <code>clamd</code> as root or with <code>sudo</code>, and you did not explicitly configure with <code>--disable-clamav</code>, you will want to ensure that the <code>DatabaseOwner</code> user specified in <code>freshclam.conf</code> owns the database directory so it can download signature updates.</p>
<p>The user that <code>clamd</code>, <code>clamdscan</code>, and <code>clamscan</code> run as may be the same user, but if it isn't -- it merely needs <em>read</em> access to the database directory.</p>
<p>If you choose to use the default <code>clamav</code> user to run <code>freshclam</code> and <code>clamd</code>, you'll need to create the clamav group and the clamav user account the first time you install ClamAV.</p>

<p>After you've installed ClamAV, you will want to make it so that the database directory is owned by the same service account as you're using for <code>freshclam</code>.</p>
<p>As root or with <code>sudo</code>, run:</p>
<pre><code class="language-bash">sudo chown -R clamav:clamav /usr/local/share/clamav
</code></pre>
<p>Or (if you customized the database path):</p>
