Let’s embark on this journey, where every step is a stride towards confidence. We will examine ClamAV for your Manjaro installation, configuration, and usage together. The need for system protection makes it more than just an option.

Let’s turn that necessity into an empowering reality.

Understanding ClamAV

Imagine your computer as a fortress, and all the files and data within are the treasures. Now, imagine antivirus software as the guards of this fortress. ClamAV serves this purpose, standing tall as the gatekeeper that ensures no unwanted intruders breach the walls.

ClamAV’s strength lies in its features:

  • Open-Source: Accessible to all and constantly refined by a global community of developers.
  • Cross-Platform: It’s versatile, working not only with Manjaro but other operating systems too.
  • Real-time Scanning: Always vigilant, scanning files, emails, and downloads as they happen.
  • Regular Updates: Continuously updated to recognize new threats & maintained by a major player in the networking industry – Cisco.

Manjaro users favor ClamAV for its compatibility and efficiency. It’s like having a well-trained guard dog that knows every corner of your home.

Threats Targeting Linux Systems

Some common villains in the Linux world include:

  • Rootkits: Stealthy and hidden, they gain unauthorized access.
  • Worms: Self-replicating nuisances that spread from system to system.
  • Ransomware: Locking you out of your files and demanding payment to release them.

Do you recall the infamous “WannaCry” ransomware attack? It affected over 200,000 computers across 150 countries. While it primarily targeted Windows systems, similar attacks have also reached Linux-based systems.

In today’s era of booming digital connectivity, an antivirus is not just a good-to-have; it’s a must-have. It’s your digital seatbelt. And ClamAV? It’s more than just a seatbelt; it’s an entire safety system tailored for Manjaro.

Preparing Your System

On unstable ground, you wouldn’t erect a house, would you? Similar to this, you must verify that your Manjaro Linux system is prepared before installing ClamAV. It’s comparable to building a strong foundation.

Downloading ClamAV

Now that your system is prepared, it’s time to download ClamAV.

sudo pacman -S clamav

Installing ClamAV

Step-by-Step Installation Guide for Terminal-base install:

  1. Update Definitions – the warning at the end is expected:

sudo freshclam

2. Enable (on startup) & start the services for clamav

sudo systemctl enable --now clamav-daemon
sudo systemctl enable --now clamav-freshclam

3. Verify ClamAV is Present

freshclam -V

Troubleshooting Common Issues:

  • Problem: Error messages while starting the service.
  • Solution: Check permissions, and if needed, run sudo freshclam to update virus databases.
  • Remember, like building anything great, sometimes it takes a little troubleshooting.

By now, ClamAV should be standing tall as the guardian of your system.

Configuring ClamAV

Customizing, optimizing, and automating are the three keys to turning your ClamAV installation into a well-oiled machine. For these configurations we’ll continue to be in the terminal. Presumably you’ll have nano, but if you prefer vim or some other editor adjust appropriately. (If you really hate yourself, you could also navigate to the directory below in whichever file explorer you’re using & work it from there. But it’s up to you – edit the file as root-enabled, write it back and call it a day.)

Customizing Settings

  1. Open ClamAV Configuration File:

sudo nano /etc/clamav/clamd.conf

  1. Set Scanning Preferences:
    • Find the line #ExcludePath ^/sys/.
    • Remove the comment (#) from the line and replace location with the the path you want to exclude from scans, such as /home/user/downloads – or add your own in the same format.
    • This excludes the specified folder from your scans.
  1. Adjust Sensitivity Level:
    • Scroll down to find #AlertEncrypted.
    • Removing the “#” will notify you of encrypted files, making the scans more sensitive.
    • Leave it as is if you prefer not to be notified about encrypted files.
  1. Optimizing for Performance:
    • Back in the clamd.conf file, find #MaxThreads.
    • Change the number to how many threads you want ClamAV to use. More threads will make scans faster but can slow down other processes.

There’s a lot of other options here, take your time to review the documentation in the file. Once you’re done tweaking – Ctrl+X, Y, [Enter] as normal if you’re using Nano to edit and there you go.

Don’t forget to restart the service – sudo systemctl restart clamav-daemon.

Scheduled Scans

Let’s start with opening crontab in our preferred editor (EG nano):

export VISUAL=nano; crontab -e

Add:

0 1 * * * clamscan -l -i -r /home

to run a scan on your home directory every day at 1 AM.

Save and exit – knowing that you’re covered.

Using ClamAV

Running Manual Scans

When in doubt, run a manual scan:

sudo clamscan -i -r /home/ | tee clamshell.log

The switch -i shows us only the infected files, if any, -r is recursive through the file structure & the tee command puts the output in a log in the current folder. Note: the reason for this is that access to the log via -l is locked as a result of being accessed elsewise. Attempting to access & write it simultaneously might cause issues. Better to avoid that.

Here’s the output of the…

Oh no! There’s a infected file – now that’s the reason why we created a log..

nano clamshell.log

Where is it found… (CTRL+W found, [enter])

Luckily, it’s only a dubious file at rest – and, in this case, a test signature from EICAR. Had this been a real discovery of malware, our discovery would only be the beginning. From there, we’d need to quarantine or delete the file after determining the nature of the threat – for the former, you can move the file with the –move [path] flag; or remove it with –remove flag applied to clamscan. Though be careful on the latter, as you might need that file later on to figure out what happened!

ClamAV: Your Guardian Against the Unknown

Now, the ball is in your court. Implement these practices, join the community of the vigilant, and take control of your digital domain. Think of ClamAV as more than a tool; it’s your personal bodyguard in a world full of uncertainties.

Let’s challenge the status quo. Why just follow the crowd when you can lead with informed choices? Raise the bar of your digital safety. Make ClamAV your chosen guardian. Together, we will redefine what it means to be secure.
