We have all had the experience of downloading a new piece of software from the Internet and after plugging it in to our computers, we find that it fails to show up in Windows right away. It may take a few minutes for the installation process to start – but then it fails to show up in the Start menu. If you try to double click on the program, it just taunts you and refuses to open. Sometimes, the program may not even start in the first place.
Raspberry Pi is a fantastic bit of kit and one of the best things to happen to electronics in a long time. However, it’s also been attacked by the usual suspects: trojans, backdoors, viruses, malware, spyware, adware, keyloggers, etc. With so many things out there (virus, malware, and adware in particular) that could potentially infect your Raspberry Pi, it’s easy to feel overwhelmed. In this article, we’ll show you how to avoid getting infected with viruses, malware, and adware, and let you know what tools you can use to keep your Pi safe.
As Raspberry Pi is getting popular, and more and more people are finding out about the security risks of this small but powerful computer, the need for a security solution to make your Raspberry Pi more secure has been requested. So, what can you do? I have recommended to my readers to run your Raspberry Pi like a standalone computer, without any complementary antivirus software.. Read more about raspberry pi security vulnerabilities and let us know what you think.Malware and other types of viruses have flooded the internet. Most are written for Windows operating systems, which forces people to use other solutions whenever possible. The Raspberry Pi is an incredibly small computer that runs on Linux. Some people think that there are no viruses for Linux, but this is not true. It happens much less often, but they do exist, and they can damage your computer, steal your data, etc. Does the Raspberry Pi need an antivirus program? It’s a good idea to install antivirus software on your Raspberry Pi computer. ClamAV is the most widely used solution, efficient and easy to install. You can improve protection without antivirus if you configure your Raspberry Pi correctly. In this article you will learn what a Raspberry Pi is and how it works, the most common security risks or issues, as well as the best antivirus software for the Raspberry Pi and how to install it.
What is a Raspberry Pi ?
The Raspberry Pi is a simple but powerful badge-sized computer with a wide range of applications. You can simply plug it into your TV or monitor and use your computer with the usual mouse and keyboard settings. You can use it to learn programming in Python, Scratch and other languages, browse the web, play HD videos, play video games, etc. It can do almost anything a normal desktop computer can. Sure, it’s not as powerful, but it gets you where you want to go, especially the newer versions like the Raspberry Pi 3 or 4. alt= width=405 height=270 data-ez= data-ezsrc=http://server.digimetriq.com/wp-content/uploads/2021/04/What-Age-Is-Raspberry-Pi-Suitable-For–.jpg /> It has a great capacity to interact with the outside world and has a wide range of applications, from arcade games to internet surfing to jukeboxes, weather stations, etc. The Raspberry Pi is a great tool for learning computer science at low cost, making it ideal for children and schools. It uses Linux as the operating system, so the security risk of using this system is much lower. The risk exists, however, and preventive measures must be taken. If you want to learn more and follow my tips for getting started with the Raspberry Pi, I recommend checking out my Raspberry Pi Bootcamp course here. It will help you take the first step in getting to know your Raspberry Pi and unlocking its secrets. Together with me you will install your first operating system and complete 5 projects with step-by-step instructions.
Does the Raspberry Pi need an antivirus program?
Installing an antivirus on your Raspberry Pi is a good idea – it costs nothing and protects you. Although few viruses can attack the Raspberry Pi, it is easier to combat them with an antivirus program than to manually reconfigure the system. Since Linux has far fewer users than Windows (90% of users on Windows and only 2% on Linux), viruses are less common. Even viruses and malware designed for Linux usually try to use Windows code running on Linux systems. Therefore, there are not many viruses that can harm your Raspberry Pi. That doesn’t mean they don’t exist – you may still be in danger, and you should do what you can to protect yourself. As more and more users choose Linux systems, hackers have begun to develop malware and other security threats for this platform. For example, cryptocurrency mining malware has recently attacked Raspberry Pi users, particularly older versions and non-upgraded devices, as well as those who have not changed their default username and password but are configured to allow remote SSH connections. It has used equipment to mine cryptocurrencies using its facilities. It is a simple Trojan horse, but it works very effectively and can go unnoticed if you don’t know what to expect. He doesn’t mine bitcoin, because it’s very difficult to mine it economically, but he does mine several other currencies.
Which antivirus should I choose for my Raspberry Pi ?
There are several antivirus software options you can install on your Raspberry Pi, but I’m only going to recommend one. ClamAV is an excellent antivirus program designed specifically for Unix systems. It provides all the protection you need and is incredibly easy to install. Once installed, you can scan your device for malware, viruses, trojans, ISP tracking and other security risks that can affect your Raspberry Pi. Once installed, the program provides you with a number of configuration options and automatically installs regular updates, so you don’t have to worry about manual updates.
How do I install ClamAV Antivirus on my Raspberry Pi?
ClamAV is a free antivirus program available in the Raspberry Pi OS repositories, so installation is easy:
- Open a terminal or SSH connection
- Update the package information with: sudo apt update
- Install ClamAV: sudo apt install clamav
That’s it. If you are working in the desktop version, you can also use the Add/Remove Programs tool in the Main Menu > Preferences : alt= width=1002 height=630 data-ezsrc=http://server.digimetriq.com/wp-content/uploads/2021/05/Does-Raspberry-Pi-Need-Antivirus-Definitive-Solution–.png /> After installation, you will need to know a few commands to use ClamAV on your Raspberry Pi. There is no graphical user interface to manage all this, only command lines. You can install the clamtk package to get the basic Python interface, or you can use the following commands, which are easy to remember:
- Start the analysis in the current folder: clamscan
- To scan a specific directory: clamscan -r /media/usb The -r option must be used for recursive scanning. Also, I think it is a good idea to use sudo to scan the whole system: sudo clamscan /
- Automatically remove all suspicious files: clamscan –remove
- Or just quarantine them: clamscan –move=/home/pi/suspicious_files/
alt= width=750 height=390 data-ez= data-ezsrc=http://server.digimetriq.com/wp-content/uploads/2021/05/Does-Raspberry-Pi-Need-Antivirus-Definitive-Solution–.jpg /> ClamAV updates its virus definitions automatically, so there’s nothing you can do about it. However, it may be useful to create a task that runs a check at regular intervals or even at startup. For all information, see this guide on scheduling tasks or this guide on starting programs at startup. As you saw in the above screenshot of the add/remove tool, there are many additional packages available for ClamAV. If you have a mail server on your Raspberry Pi or want to manage it with Python scripts, you can check it out. But for a single user on a Raspberry Pi, the standard clamscan command is probably sufficient.
Most common security risks on Raspberry Pi devices
Before I continue with the examples, I should point out that viruses and malware are not the only security problem with the Raspberry Pi. Most security risks for Raspberry Pi devices occur when you forget to change the default username and password. On each device, the default username is pi and the password is raspberry. Or, better yet, you can create a new user and then delete the default Pi user. The mining malware mentioned above also targets these devices, as it is very easy to break into them and change the code. Changing the default username and password is a good start to securing your Raspberry Pi computer. alt= width=800 height=316 data-ez= data-ezsrc=http://server.digimetriq.com/wp-content/uploads/2021/05/1622187025_228_Does-Raspberry-Pi-Need-Antivirus-Definitive-Solution–.jpg /> One of the most common uses of the Raspberry Pi is as a Kodi media center. You can watch videos, listen to music, read the news, etc., but the risk arises when you install add-ons that contain malware. If you are not using antivirus on your device, installing Kodi add-ons would not be the wisest decision. There are other risks with Kodi Media Center, but you can solve them all by simply installing an antivirus program. By the way, using a VPN on Kodi (as explained here) is also a good idea to protect your data and bypass land restrictions. If you are using a Raspberry Pi as a web server, you are vulnerable to various attacks, especially if you are using WordPress. Its popularity has led to frequent attacks by hackers. Regular updates and antivirus software will protect you well, even better than Windows systems. Using a firewall and additional protection such as Fail2ban to block malicious traffic is also a good practice to protect your system and network. Just like any other game server, your Raspberry Pi server can be under constant attack, even if you have an antivirus program installed. Sometimes the device can be used as an arcade game server, and if you do not take the necessary security measures, it is vulnerable to attacks. Ultimately, the biggest danger comes from the hardware – the devices you connect to your Raspberry Pi. If the device is infected or can open the door to your network, it can also infect the Pi.
