How to Use Antivirus Software on MacOS Or Linux Systems?

16 minutes read

Antivirus software is essential for maintaining the security of your computer, even if you are using macOS or Linux systems. While these operating systems are generally more secure than Windows, they are still susceptible to malware and other threats. Here is a text guide on how to use antivirus software on macOS or Linux systems:

  1. Research and choose an antivirus software: There are numerous antivirus software options available for macOS and Linux. Look for reputable brands and read reviews to find one that suits your needs. Some popular choices include Avast, Bitdefender, Sophos, and ClamAV.
  2. Download and install the antivirus software: Visit the official website of your chosen antivirus software, look for the appropriate version for your operating system, and download the installation file. Once downloaded, run the installer and follow the on-screen instructions to complete the installation.
  3. Update the antivirus software: After installation, launch the antivirus software and check for any available updates. Keeping your antivirus software up to date ensures that it can effectively detect and protect against the latest threats.
  4. Configure real-time scanning: Real-time scanning is a crucial feature that continuously monitors your system for malicious files and activities. Open the antivirus software and navigate to the settings or preferences. Enable real-time scanning and choose the appropriate settings according to your preferences.
  5. Run a full system scan: Once you have configured the settings, perform a full system scan using the antivirus software. This scan will thoroughly examine all files and directories on your computer for any signs of malware or suspicious activities.
  6. Quarantine or remove detected threats: After the scan is complete, the antivirus software will display a list of detected threats. Quarantine or remove these threats based on the recommendations of the software. Quarantining isolates the detected files, allowing you to review and decide their fate, while removal deletes them immediately.
  7. Schedule regular scans: To ensure continuous protection, set up regular scans using the scheduling options provided by the antivirus software. This way, you won't have to manually initiate scans every time.
  8. Stay vigilant and practice safe browsing habits: While antivirus software is crucial, it's important to remember that it's just one layer of defense. It's equally essential to practice safe browsing habits, avoid suspicious websites or downloads, and exercise caution while opening email attachments or clicking on links.


Remember, antivirus software is designed to supplement your computer's security, but it's not foolproof. Combining it with regular software updates, secure browsing habits, and regular backups will provide a comprehensive defense against potential threats on macOS or Linux systems.

To disable the antivirus temporarily on Linux, follow these steps:

  1. Open a terminal window.
  2. Determine the name of your antivirus software. Common Linux antivirus programs include ClamAV, Sophos, and Bitdefender. Use the relevant command to identify the running antivirus service. For example, for ClamAV, use: sudo systemctl status clamav-daemon
  3. Once you have identified the antivirus software, use the appropriate command to stop or disable the antivirus service. Here are the commands for some popular antivirus programs: ClamAV: sudo systemctl stop clamav-daemon Sophos: sudo /opt/sophos-av/bin/savdstop Bitdefender: sudo /etc/init.d/bitdefender-antivirus stop
  4. Confirm that the antivirus service has been stopped by checking its status again: sudo systemctl status clamav-daemon If the service is stopped, it should display "Active: inactive (dead)" or a similar message.


Please note that disabling your antivirus temporarily increases the risk of malware infecting your system. Hence, it is recommended to disable the antivirus only when necessary and enable it again as soon as possible.

  4. Wait for the scan to complete. It will display the progress, and any infected files will be listed in the terminal.
  5. If you want to scan your entire system, start the scan at the root directory by running: sudo clamscan -r / This will scan all files and directories recursively starting from the root directory.
  6. You can also scan all files owned by a specific user with the following command: sudo clamscan -r --exclude-dir="^/sys|^/proc|^/run|^/dev|^/var/lib/clamav" --remove /home/username/ Replace "username" with the actual username whose files you want to scan.


Note: You might need to install ClamAV first if it's not already installed on your Linux distribution. Use the package manager for your specific distribution to install it.
