Prerequisites Make sure ClamAV is properly installed and XWall can communicate native with the ClamAV service See also Install ClamAV Antivirus Native Win32 SaneSecurity Rules You have two options to download the rules: Either using the old ClamSup, which has more options, or using the new Sigupdate, which is simpler to install. Using ClamSup (this no longer works, because the download links are invalid) Download ClamSup.zip Latest ClamSup.ini Rsync for Windows Note: You need to open port 873 in the firewall to make cwRsync working. Create a directory named ClamSup beside the ClamAV directory e.g. assuming that ClamAV is in C:\ClamAV then create C:\ClamSup Extract the downloaded files into the ClamSup directory Open ClamSup.cfg with an editor and adjust the path so that it matches your ClamAV installation Make sure the line LOCALFOLDER=C:\ClamAV\db points to the db folder in the ClamAV directory. Open a DOS Box, change to the ClamSup directory and type start ClamSup.bat -v ClamSup will run for a few minutes and download all SaneSecurity databases. After the download ClamSup copies the databases into the ClamAV db folder and restarts ClamAV. In the case ClamSup.bat immediately closes, locate clamsup.error and check the error. Once you fixed the error, start ClamSup.bat again. Create a schedule that starts ClamSup.bat every 2 hours Using Sigupdate From download ClamWin/ClamAV Sigupdate 0.4 beta Note: You need to open port 873 in the firewall to make cwRsync working. Create a directory named Sigupdate beside the ClamAV directory e.g. assuming that ClamAV is in C:\ClamAV
Re: [Clamav-announce] ClamAV? blog: ClamAV 0.102.4
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 workclamav/clamav-for-windows at 0.98.4 - clamav - Gitea: Git with a

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. If you choose to install with the Software Center, you just have to search for "ClamAV" and you should see the antivirus and the option to install it.Now, for those who choose the option to install from the terminal They only have to open one on their system. yum install clamav-server clamav-data clamav-update clamav-filesystem clamav clamav-scanner-systemd clamav-devel clamav-lib clamav-server-systemd.

2025-04-06ClamAV Bytecode Compiler The ClamAV® Bytecode Compiler is a tool to build cross-platform advanced malware detection plugins for the ClamAV® open source antivirus engine. We call these plugins "bytecode signatures". Bytecode signatures are are executed by a ClamAV using either an LLVM JIT runtime or an interpreter runtime. These signatures extend ClamAV's file format support and provide detection capabilities above and beyond the limitations of content-based logical signatures. DocumentationAt present the pdf documentation is dated.Specifically, the instructions for building the compiler or no longer correct.The documentation will be updated as time permits.The PDF documentation still provides valuable instructions for writing andcompiling signatures, and documents features of the bytecode signature API.Quick StartGetting the bytecode compiler repositorygit clone git://github.com/Cisco-Talos/clamav-bytecode-compilerQuick start for building & installingRequirementsLLVM and Clang, version 8 or newerLLVM and Clang versions must match.Version 8 is preferred, tested. Newer versions are not guaranteed to work correctly.LLVM is required to build the bytecode compiler.Clang is required to run the bytecode compiler.Python 3.6 or newer.Python is required to run the unit tests, and to run the bytecode compiler.Build & InstallConfigure:">mkdir build && cd buildcmake .. \ -D CMAKE_BUILD_TYPE=Release \ -D CMAKE_INSTALL_PREFIX=install path>Build:Test:Install:cmake --build . --target installAdditional Build ExamplesBuild with a specific LLVM version and specific ClamAV install that installs tolocal directory:cmake .. \ -D CMAKE_INSTALL_PREFIX=install \ -D ENABLE_TESTS=ON \ -D LLVM_ROOT=/usr/lib/llvm-8 \ -D ClamAV_HOME=$HOME/clams/0.105.0make -j12ctest -Vmake installChange LogFor information about the features in this and prior releases, readthe news.Join the ClamAV CommunityThe best way to get in touch with the ClamAV community is to join ourmailing lists and tojoin us on Discord.Want to make a contribution?The ClamAV development team welcomescode contributions.Thanks for joining us!LicensingClamAV is licensed for public/open source use under the GNU General PublicLicense, Version 2 (GPLv2).See COPYING/COPYING.txt for a copy of the license.3rd Party CodeClamAV contains a number of components that include code copied in part or inwhole from 3rd party projects and whose code is not owned by Cisco and whichare licensed differently than ClamAV.
