Clamav for windows

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

Then create C:\Sigupdate Extract the downloaded files into the Sigupdate directory Download Rsync for Windows Note: You need to open port 873 in the firewall to make cwRsync working. Extract the file in the bin directory into the Sigupdate\winrsync directory Open Sigupdate.bat with an editor and adjust the path so that it matches your ClamAV installation Open a DOS Box, change to the ClamSup directory and type Sigupdate.bat Sigupdate will run for a few seconds and download all SaneSecurity databases. After the download Sigupdate copies the databases into the ClamAV db folder and restarts ClamAV. Create a schedule that starts Sigupdate.bat every 2 hours In XWall enable Options->Spam->SaneSecurity and send a test message. ClamAV Configuration Suggested settings for ClamAV in clamd.conf: LogFile c:\Clamav\log\clamd.log DatabaseDirectory c:\clamav\db LogTime true LogFileMaxSize 20480000 TCPSocket 3310 # Twice as much ClamAV threads as worker threads in XWall MaxThreads 40 # Disable Zip in ClamAV and uncheck Options->Virus->Options->Scanner supports ZIP ScanArchive no # No Phishing, because ClamAV gets confused by simple forwards PhishingScanURLs no # No need that ClamAV decodes the message, XWall already does it ScanMail no # Must be enabled when checking for Office Macros with Options->ClamAV->Macro #ScanOLE2 yes #OLE2BlockMacros yes #In case freshclam can't connect to clamd #TCPAddr 10.0.0.1 Testing SaneSecurity Save the following message into a file and send the file using SMTPSend and the -g option to XWall. SaneSecurity should detect the special subject as a test message. For more information on signature testing see _Begin of SaneSecurity test message_ From:

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.

Not surprising there would be errors on the windows side. I looked quickly and saw several windows issues with paths on github and the mailing list.I would give it some time before upgrading. Better yet, send clamav log entries to the mailing list or post an issue on github. If they don't know about an issue, they won't be able to fix it.
