How to use ClamAV to run an antivirus scan of you Macintosh

As a Macintosh user, you might have heard the myth that Macs are immune to viruses. Unfortunately, this is not entirely true. While Macs are less susceptible to viruses than PCs, they are not completely invincible. This is where ClamAV comes in. ClamAV is a free, open-source antivirus software that can help protect your Mac from malicious software. In this article, we will guide you on how to use ClamAV to run an antivirus scan on your Macintosh.

Understanding ClamAV

Before we delve into the how-to, let’s first understand what ClamAV is. ClamAV is an open-source antivirus engine designed for detecting Trojans, viruses, malware, and other malicious threats. It is the standard for mail gateway scanning software and is used on mail servers, file servers, and other server applications where virus detection is necessary.

Why Choose ClamAV?

ClamAV is a popular choice for several reasons:

  • It’s free and open-source, meaning you can modify it to suit your needs.
  • It offers a command-line scanner, which can be a powerful tool for advanced users.
  • It provides a versatile multi-threaded daemon, a command-line scanner, and an advanced tool for automatic database updates.
  • It supports multiple file formats, file and archive unpacking, and multiple signature languages.

Installing ClamAV on Your Mac

Now that we understand what ClamAV is and why it’s a good choice, let’s move on to the installation process. Here’s a step-by-step guide:

  1. Open Terminal on your Mac. You can find it in the Utilities folder within your Applications folder.
  2. Type in the following command: ruby -e "$(curl -fsSL" This command installs Homebrew, a package manager for macOS that simplifies the installation of software on Apple’s macOS operating system.
  3. Once Homebrew is installed, type in the following command to install ClamAV: brew install clamav
  4. Wait for the installation process to complete.

Running a ClamAV Scan on Your Mac

After successfully installing ClamAV, you can now run an antivirus scan on your Mac. Here’s how:

  1. Open Terminal again.
  2. Type in the following command to update ClamAV’s database: freshclam
  3. Once the database is updated, you can now run a scan. To do this, type in the following command: clamscan -r --bell -i / This command will scan your entire system and alert you if it finds any infected files.

Interpreting the Scan Results

After running the scan, ClamAV will provide you with a summary of the scan results. If ClamAV finds any infected files, it will list them along with the type of malware detected. It’s important to take action on these infected files to ensure your Mac’s security.

Keeping Your Mac Secure with ClamAV

While running an antivirus scan is a good first step, it’s also important to keep your antivirus software updated to protect against the latest threats. You can do this by regularly running the freshclam command in Terminal to update ClamAV’s database.

Additionally, consider scheduling regular scans to ensure your Mac stays protected. You can do this by setting up a cron job, a time-based job scheduler in Unix-like operating systems. This way, you won’t have to manually run scans, and you can rest assured that your Mac is regularly checked for threats.


In conclusion, while Macs are generally more secure than PCs, they are not completely immune to viruses. Therefore, it’s important to take steps to protect your Mac from potential threats. ClamAV is a powerful tool that can help you do this. By following the steps outlined in this article, you can install ClamAV, run an antivirus scan, and keep your Mac secure. Remember, the key to maintaining a secure system is regular updates and scans. So, don’t forget to update ClamAV’s database regularly and schedule regular scans to ensure your Mac stays protected.
