ClamAV Antivirus for Linux Tutorial

ClamAV is an open source antivirus softwareThrough a Cisco blog post recently disclosed, the new version release correction of your free antivirus package «ClamAV 1.1.1», along with which versions 1.0.2 and 0.103.9 have been released.For those unaware of ClamAV you should know that this is an open source antivirus and multiplatform (It has versions for Windows, GNU / Linux, BSD, Solaris, Mac OS X and other Unix-like operating systems).ClamAV 1.1.1 Main New FeaturesIn the new version of ClamAV 1.1.1 presented, the main novelty is the implementation of the vulnerability fix (already cataloged under CVE-2023-20197) that causes a denial of service when scanning ClamAV files with files especially disk images formatted in the HFS+ format. It is mentioned that this is the second vulnerability in the HFS+ file scanner this year, as a previous issue allowed code to be executed with the rights of the ClamAV process and was recognized by the Pwnie Awards as the best remote code execution vulnerability of the year.Other changes that stand out is that The CMake compilation system was improved to support building with OpenSSL 3.x on macOS with the Xcode toolchain. The official ClamAV installers and packages are now built with OpenSSL 3.1.1 or later.In addition to this, it is also mentioned that fixed a build issue when using Rust's nightly toolchain, which affected the oss -fuzz build environment used for regression testing, and fixed a build issue on Windows when using Rust version 1.70 or later.For the part of the changes in the version of ClamAV 1.0.2, In addition to also fixing the CVE-2023-20197 vulnerability, this version arrives by fixing a vulnerability specific to the 1.0.x branch (cataloged under CVE-2023-20212) which resulted in a denial of service when analyzing AutoIt data.Non-security fixes include:Improved support for compiling with OpenSSL 3.x on macOSFix build issues on Windows when using the Rust 1.70+ toolkitProvide support for nightly builds of the Rust toolkit.Fixed an issue for ClamAV to correctly remove temporary files generated by the VBA and XLM extraction modules so that the files are not leaked in patched versions of ClamAV.Removed a warning message showing HTTP response codes during the Freshclam database update process.Fixed two bugs that caused freshclam upgrade fails when applying a CDIFF database patchfinally if you are interested in knowing more about it, you can check the details In the following link.How to install ClamAV in Ubuntu and derivatives?For those who are interested in being able to install this antivirus on their system, they can do it in a fairly simple way and that is ClamAV is found within the repositories of most Linux distributions.In the case of Ubuntu and its derivatives, you can install it from the terminal or from the system software center.

Changing your passwords after a while, especially if you suspect your password has been compromised. This will help to prevent unauthorized access to the system and protect sensitive information that would otherwise be leaked.3. Enabling the firewallA firewall is a network security system that monitors and controls incoming and outgoing traffic based on predefined security rules. It acts as a barrier between your system and the internet, blocking traffic that doesn’t meet the specified criteria.In Linux Mint, the firewall is called “ufw” (Uncomplicated Firewall) and is pre-installed by default. To enable the firewall, open a terminal and enter the following command:sudo ufw enableEnabling firewall on Linux MintThis will activate the firewall and set it to start automatically at boot time. Once enabled, you can configure the firewall rules to allow or deny incoming and outgoing traffic based on the specific needs of your system. To allow incoming SSH traffic (port 22), enter the following command:sudo ufw allow sshAllowing incoming SSH trafficTo allow incoming HTTP traffic (port 80), enter the following command:sudo ufw allow httpAllowing incoming HTTP trafficTo deny incoming FTP traffic (port 21), enter the following command:sudo ufw deny ftpDenying incoming FTP trafficYou can also view the firewall’s status at any time. This will show you which rules are active and which ports are open or closed.sudo ufw statusViewing firewall status on Linux MintBy enabling and configuring the firewall, you can significantly improve the system’s security and protect it against possible breaches. Review and update your firewall rules regularly to protect your system against the latest security threats.4. Installing antivirus softwareAntivirus detects and removes malicious software from your system, such as viruses, trojans, and spyware. It can also prevent malware from infecting your system in the first place by scanning incoming files and email attachments.Several antivirus software options are available for Linux Mint, including ClamAV, Sophos, and Bitdefender. ClamAV is a popular open-source antivirus pre-installed on some Linux distributions, including Mint. Sophos and Bitdefender are other commercial options that offer advanced features such as real-time scanning and web protection.To install or enable ClamAV on Linux Mint, open the terminal and enter the following command:sudo apt-get install clamavInstalling ClamAV on Linux MintDownload the software from the vendor’s website to install Sophos or Bitdefender and follow their installation instructions. Once installed, make sure to regularly update the antivirus so that it can detect and remove the latest threats. You should also schedule regular scans of your system to check for any malware that may have slipped through the cracks.5. Disabling unnecessary services and applicationsDisabling unnecessary services and applications results in reducing the attack surface of your Linux Mint system. By disabling services that are not needed anymore, you can significantly diminish the number of potential vulnerabilities that an attacker can exploit.To disable unnecessary services, open the “System Monitor” and look for processes that are not being used. Services not needed for your system’s functionality can be disabled using the “systemctl” command. To disable the “cups” service, which is used for printing, enter.

New Requirements:- As of ClamAV 0.104, CMake is required to build ClamAV- We have added comprehensive build instructions for using CMake to the new INSTALL.md file. The online documentation will also be updated to include CMake build instructions.- The Autotools and the Visual Studio build systems have been removedMajor changes:- The built-in LLVM for the bytecode runtime has been removed- The bytecode interpreter is the default runtime for bytecode signatures just as it was in ClamAV 0.103- We hoped to add support for newer versions of LLVM, but ran out of time. If you're building ClamAV from source and you wish to use LLVM instead of the bytecode interpreter, you will need to supply the development libraries for LLVM version 3.6.2. See the "bytecode runtime" section in INSTALL.md to learn more.- There are now official ClamAV images on Docker HubDocker Hub ClamAV tags:- clamav/clamav:: A release preloaded with signature databases- Using this container will save the ClamAV project some bandwidth. Use this if you will keep the image around so that you don't download the entire database set every time you start a new container. Updating with FreshClam from the existing databases set does not use much data.- clamav/clamav:_base: A release with no signature databases- Use this container only if you mount a volume in your container under /var/lib/clamav to persist your signature database databases. This method is the best option because it will reduce data costs for ClamAV and for the Docker registry, but it does require advanced familiarity with Linux and Docker.- Caution: Using this image without mounting an existing database directory will cause FreshClam to download the entire database set each time you start a new container.- You can use the unstable version (i.e. clamav/clamav:unstable or clamav/clamav:unstable_base) to try the latest from our development branch.- Please, be kind when using 'free' bandwidth, both for the virus databases but also the Docker registry. Try not to download the entire database set or the larger ClamAV database images on a regular basis.- For more details, see the ClamAV Docker documentation- Special thanks to Olliver Schinagl for his excellent work

Antivirus Live CD is a Linux distribution based on 4MLinux that includes the ClamAV scanner. It's built for system admins who need a lightweight live CD with an antivirus scanner. A new versions has been released and is now available for download.The Antivirus Live CD project has been out for some time, but it has changed very little. Its developers have only upgraded the base from time to time and the definitions.As the name suggests, this is the primary function of this tool and it's important to have everything up to date, especially the Linux definition. They can be downloaded from the Internet before the scanning process is started, but there is also a version of the distro that already has them integrated.Some users might wonder what the role of the Antivirus Live CD would be for the Linux platform, and the answer to that question is simple. It's not designed for Linux users, although it's perfectly capable of scanning Linux partitions, if necessary.This system is built to scan other operating systems as well, like Windows for example, and it can do it from the outside.Antivirus Live CD always has the latest virus definitionsThe operating system doesn't have a Linux distribution and you might think that it's not user friendly, but that's not the case. Users only have to run the "antivir" command and they will be presented with three simple choices, to scan the computer, to upgrade the virus signature, or to update the ClamAV software. It's also possible to run Midnight Commander in order to get access to some basic functions, like copy, move, or delete."Antivirus Live CD is a 4MLinux fork including the ClamAV scanner. It's designed for users who need a lightweight live CD, which will help them to protect their computers against viruses. Both Ethernet
