Note: This README/NEWS file refers to the source tarball. Some things described here may not be available in binary packages. -- 0.98 ------ ClamAV 0.98 includes many new features, across all the different components of ClamAV. There are new scanning options, extensions to the libclamav API, support for additional filetypes and internal upgrades. - Signature improvements: New signature targets have been added for PDF files, Flash files and Java class files. NOTE: Java archive files (JAR) are not part of the Java target. Hash signatures can now be written with a * size if the size is unknown. Using wildcard size requires setting the minimum engine FLEVEL to avoid backwards compatibility issues. For more details read the ClamAV Signatures guide. - Scanning enhancements: New filetypes can be unpacked and scanned, including ISO9660, Flash and self-extracting 7z files. PDF handling is now more robust and better handles encrypted PDF files. - Authenticode: ClamAV is now aware of the certificate chain when scanning signed PE files. When the database contains signatures for trusted root certificate authorities, the engine can whitelist PE files with a valid signature. The same database file can also include known compromised certificates to be rejected! This feature can also be disabled in clamd.conf (DisableCertCheck) or the command-line (nocerts). - New options: Several new options for clamscan and clamd have been added. For example, ClamAV can be set to print infected files and error files and suppress printing OK results. This can be helpful when scanning large numbers of files. This new option is "-o" for clamscan and "LogClean" for clamd. Check clamd.conf or the clamscan help message for specific details. - New callbacks added to the API: The libclamav API has additional hooks for developers to use when wrapping ClamAV scanning. These function types are defined to start with "clcb_" and allow developers to add logic at certain steps of the scanning process without directly modifying the library. For more details refer to the clamav.h file. - More configurable limits: Several hardcoded values are now configurable parameters, providing more options for tuning the engine to match your needs. Check clamd.conf or the clamscan help message for specific details. - Performance improvements: This release furthers the use of memory maps during scanning and unpacking, continuing the conversion started in prior releases. Complex math functions have been switched from libtommath to tomsfastmath functions. The A/C matcher code has also been optimized to provide a speed boost. - Support for on-access scanning using Clamuko/Dazuko has been replaced with fanotify. Accordingly, clamd.conf settings related to on-access scanning have had Clamuko removed from the name. Clamuko-specific configuration items have been marked deprecated and should no longer be used. There are also fixes for other minor issues and code quality changes. Please see the ChangeLog file for details. -- The ClamAV team ( 0.97.8 ---- ClamAV 0.97.8 addresses several reported potential security bugs. Thanks to Felix Groebert of the Google Security Team for finding and reporting these issues. 0.97.7 ---- ClamAV 0.97.7 addresses several reported potential security bugs.

It will allow selected individuals/organizations to publish ClamAV Virus Databases (CVD) through the ClamAV mirror network. If you choose to publish your signatures through our Third Party web interface you will benefit from the following: - before publishing the signatures, we will test them for false positives against our false positive file collection. - before publishing the signatures, we'll verify that the latest two major versions of ClamAV can load them correctly. - the signatures will be digitally signed and packaged into a single .cvd compressed file. - there will be no ".UNOFFICIAL" suffix in the detection names. - a custom prefix will be added to the detection names, identifying the organization which published the signature. - updates will be distributed both as full CVD files and cdiff incremental updates. Users will benefit from lower network traffic. - the .cvd and .cdiff files will be distributed through the ClamAV mirror network. - the service should result in faster remediation of false positives. - ClamAV users will be able to download the third party databases using freshclam, by adding a single line to freshclam.conf, what should make signature maintenance significantly easier. The service is still in beta, you are welcome to contact Luca Gibelli <luca*> if you intend to join the beta program. We especially welcome those who already distribute their own unofficial signatures to join. A list of databases distributed by the new service will be available at We will be happy to answer any questions you might have. -- The ClamAV team ( 0.97.1 ------ This is a bugfix release recommended for all users. Please refer to the ChangeLog file for details. -- The ClamAV team ( 0.97 ---- ClamAV 0.97 brings many improvements, including complete Windows support (all major components compile out-of-box under Visual Studio), support for signatures based on SHA1 and SHA256, better error detection, as well as speed and memory optimizations.

This upgrade is recommended for all users. 0.96.1 ------ This is a bugfix release, please refer to the ChangeLog for the complete list of changes. -- The ClamAV team ( 0.96 ---- This release of ClamAV introduces new malware detection mechanisms and other significant improvements to the scan engine. The key features include: - The Bytecode Interpreter: the interpreter built into LibClamAV allows the signature writers to create and distribute very complex detection routines and remotely enhance the scanner's functionality - Heuristic improvements: improve the PE heuristics detection engine by adding support of bogus icons and fake PE header information. In a nutshell, ClamAV can now detect malware that tries to disguise itself as a harmless application by using the most common Windows program icons. - Signature Improvements: logical signature improvements to allow more detailed matching and referencing groups of signatures. Additionally, improvements to wildcard matching on word boundaries and newlines. - Support for new archives: 7zip, InstallShield and CPIO. LibClamAV can now transparently unpack and inspect their contents. - Support for new executable file formats: 64-bit ELF files and OS X Universal Binaries with Mach-O files. Additionally, the PE module can now decompress and inspect executables packed with UPX 3.0. - Support for DazukoFS in clamd - Performance improvements: overall performance improvements and memory optimizations for a better overall resource utilization experience. - Native Windows Support: ClamAV will now build natively under Visual Studio. This will allow 3rd Party application developers on Windows to easily integrate LibClamAV into their applications. The complete list of changes is available in the ChangeLog file. For upgrade notes and tips please see: -- The ClamAV team ( 0.95.3 ------ ClamAV 0.95.3 is a bugfix release recommended for all users. Please refer to the ChangeLog included in the source distribution for the list of changes. -- The ClamAV team ( 0.95.2 ------ This version improves handling of archives, adds support for --file-list in clamscan and clamdscan, and fixes various issues found in previous releases. -- The ClamAV team ( 0.95.1 ------ This is a bugfix release only, please see the ChangeLog for details. -- The ClamAV team ( 0.95 ---- ClamAV 0.95 introduces many bugfixes, improvements and additions. To make the transition easier, we put various tips and upgrade notes on this page: For detailed list of changes and bugfixes, please see the ChangeLog. The following are the key features of this release: - Google Safe Browsing support: in addition to the heuristic and signature based phishing detection mechanisms already available in ClamAV, the scanner can now make use of the Google's blacklists of suspected phishing and malware sites. The ClamAV Project distributes a constantly updated Safe Browsing database, which can be automatically fetched by freshclam. For more information, please see freshclam.conf(5) and - New clamav-milter: The program has been redesigned and rewritten from scratch. The most notable difference is that the internal mode has been dropped which means that now a working clamd companion is required. The milter now also has its own configuration file. - Clamd extensions: The protocol has been extended to lighten the load that clamd puts on the system, solve limitations of the old protocol, and reduce latency when signature updates are received. For more information about the new extensions please see the official documentation and the upgrade notes. - Improved API: The API used to program ClamAV's engine (libclamav) has been redesigned to use modern object-oriented techniques and solves various API/ABI compatibility issues between old and new releases. You can find more information in Section 6 of clamdoc.pdf and in the upgrade notes. - ClamdTOP: This is a new program that allows system administrators to monitor clamd. It provides information about the items in the clamd's queue, clamd's memory usage, and the version of the signature database, all in real-time and in nice curses-based interface. - Memory Pool Allocator: Libclamav now includes its own memory pool allocator based on memory mapping. This new solution replaces the traditional malloc/free system for the copy of the signatures that is kept in memory. As a result, clamd requires much less memory, particularly when signature updates are received and the database is loaded into memory. - Unified Option Parser: Prior to version 0.95 each program in ClamAV's suite of programs had its own set of runtime options. The new general parser brings consistency of use and validation to these options across the suite. Some command line switches of clamscan have been renamed (the old ones will still be accepted but will have no effect and will result in warnings), please see clamscan(1) and clamscan --help for the details. -- The ClamAV team ( 0.94.2 ------ This is a bugfix release, please refer to the ChangeLog for a complete list of changes. -- The ClamAV team ( 0.94.1 ------ ClamAV 0.94.1 fixes some issues that were found in previous releases and includes one new feature, "Malware Statistics Gathering." This is an optional feature that allows ClamAV users optionally to submit statistics to us about what they detect in the field. We will then use these data to determine what types of malware are the most detected in the field and in what geographic area they are. It will also allow us to publish summary data on where our users will be able to monitor the latest threats. You can help us by enabling SubmitDetectionStats in freshclam.conf. For more details, please refer to the ChangeLog and -- The ClamAV team ( 0.94 ---- Sourcefire and the ClamAV team are pleased to announce the release of ClamAV 0.94. The following are the key features and improvements of this version: - Logical Signatures: The logical signature technology uses operators such as AND, OR and NOT to allow the combination of more than one signature into one entry in the signature database resulting in more detailed and flexible pattern matching. - Anti-phishing Technology: Users can now change the priority and reporting of ClamAV's heuristic anti-phishing scanner within the detection engine process. They can choose whether, when scanning a supicious file, ClamAV should stop scanning and report the phish, or continue to scan in case the file contains other malware (clamd: HeuristicScanPrecedence, clamscan: --heuristic-scan-precedence) - Disassembly Engine: The initial version of the disassembly engine improves ClamAV's detection abilities. - PUA Detection: Users can now decide which PUA signatures should be loaded (clamd: ExcludePUA, IncludePUA; clamscan: --exclude-pua, --include-pua) - Data Loss Prevention (DLP): This version includes a new module that, when enabled, scans data for the inclusion of US formated Social Security Numbers and credit card numbers (clamd: StructuredDataDetection, clamscan: --detect-structured; additional fine-tuning options are available) - IPv6 Support: Freshclam now supports IPv6 - Improved Scanning of Scripts: The normalization of scripts now covers JavaScript - Improved QA and Unit Testing: The improved QA process now includes API testing and new library of test files in various formats that are tested on a wide variety of systems (try running 'make check' in the source directory) For more details, please refer to and to the ChangeLog. You may need to run 'ldconfig' after installing this version. ** This version drops the special support for Cygwin. Our QA process showed ** serious problems with ClamAV builds under Cygwin due to some low-level ** incompatibilities in the POSIX compatibility layer, resulting in unreliable ** ClamAV behaviour. -- The ClamAV team ( 0.93.3 ------ This release fixes a problem in handling of .cld files introduced in 0.93.2. -- The ClamAV team ( 0.93.2 ------ This release fixes and re-enables the Petite unpacker, improves database loading and solves some other minor issues. 0.93.1 ------ This version improves handling of PDF, CAB, RTF, OLE2 and HTML files and includes various bugfixes for 0.93 issues. -- The ClamAV team ( 0.93 ---- This release introduces many new features and engine enhancements, please see the notes below for the list of major changes. The most visible one is the new logic in scan limits which affects some command line and config options of clamscan and clamd. Please see clamscan(1) and clamd.conf(5) and the example config file for more information on the new options. Most important changes include: * libclamav: - New logic in scan limits: provides much more efficient protection against DoS attacks but also results in different command line and config options to clamscan and clamd (see below) - New/improved modules: unzip, SIS, cabinet, CHM, SZDD, text normalisator, entity converter - Improved filetype detection; filetype definitions can be remotely updated - Support for .cld containers (which replace .inc directories) - Improved pattern matcher and signature formats - More efficient scanning of HTML files - Many other improvements * clamd: - NEW CONFIG FILE OPTIONS: MaxScanSize, MaxFileSize, MaxRecursion, MaxFiles - ** THE FOLLOWING OPTIONS ARE NO LONGER SUPPORTED **: MailMaxRecursion, ArchiveMaxFileSize, ArchiveMaxRecursion, ArchiveMaxFiles, ArchiveMaxCompressionRatio, ArchiveBlockMax * clamscan: - NEW CMDLINE OPTIONS: --max-filesize, --max-scansize - REMOVED OPTIONS: --block-max, --max-space, --max-ratio * freshclam: - NEW CONFIG OPTION CompressLocalDatabase - NEW CMDLINE SWITCH --no-warnings - and directories are no longer used by ClamAV; please remove them manually from your database directory -- The ClamAV team ( 0.92.1 ------ This is a bugfix release, please refer to the ChangeLog for a complete list of changes. -- The ClamAV team ( 0.92 ---- This release provides various bugfixes, optimisations and improvements to the scanning engine. The new features include support for ARJ and SFX-ARJ archives, AutoIt, basic SPF parser in clamav-milter (to reduce phishing false-positives), faster scanning and others (see ChangeLog). To get a consistent behaviour of the anti-phishing module on all platforms, libclamav now includes the regex library from OpenBSD. -- The ClamAV team ( 0.91.2 ------- This release fixes various bugs in libclamav, freshclam and clamav-milter, and adds support for PUA (Potentially Unwanted Application) signatures (clamscan: --detect-pua, clamd: DetectPUA). ** Announcement ** Dear ClamAV users, On August 17, Sourcefire, the creators of Snort, acquired the ClamAV project. The full announcement is available here: We'd like to thank everyone in the ClamAV community for their dedication to the project. The acquisition by Sourcefire is a testament to the hard work of the entire ClamAV community in developing cutting edge technology that truly showcases the promise of the open source model. With the additional resources Sourcefire will provide we look forward to working with the community to continue the advancement of ClamAV. Sourcefire now owns ClamAV project and related trademarks, as well as the source code copyrights held by the five principal members of the ClamAV team. Sourcefire will also assume control of the ClamAV project including: the domain, web site and web site content; and the ClamAV Sourceforge project page. What's most important is that from the end-user perspective very little will change beyond the additional resources Sourcefire will provide in our continued efforts to advance the ClamAV technology and improve our ability to interact with the open source community. The core team will continue to lead the advancement of ClamAV and the CVD as employees of Sourcefire. Both the ClamAV engine and the signature database will remain under GPL. For more information please visit our website and the following FAQ page: -- The ClamAV team ( 0.91.1 ------ This release fixes stability and other issues of 0.91. -- The ClamAV team ( 0.91 ---- ClamAV 0.91 is the first release to enable the anti-phishing technology in default builds. This technology combines heuristics with special signatures and provides effective protection against phishing threats. Other important changes and add-ons in this version include: - unpacker for NSIS (Nullsoft Scriptable Install System) self-extracting archives - unpacker for ASPack 2.12 - new implementation of the Aho-Corasick pattern matcher providing better detection for wildcard enabled signatures - support for nibble matching and floating offsets - improved handling of .mdb files (fixes long startup times) - extraction of PE files embedded into other executables - better handling of PE & UPX - removed dependency on libcurl (improves stability) - libclamav.dll available under Windows - IPv6 support in clamav-milter - many other improvements and bugfixes -- The ClamAV team ( 0.90.3 ------ This release fixes some security bugs in libclamav and improves stability under Solaris. Please see ChangeLog for complete list of changes. If your system is suffering from long clamscan startup times, please consider installing 0.91rc1 which is due to be released shortly after 0.90.3. -- The ClamAV team ( 0.90.2 ------ This release fixes many problems in libclamav and freshclam. -- The ClamAV team ( 0.90.1 ------ This release includes various bugfixes and code enhancements. Please see ChangeLog for complete list of changes. ** Important note **: please run 'ldconfig' after installing this version. -- The ClamAV team ( 0.90 ---- The ClamAV team is proud to announce the long awaited ClamAV 0.90. This version introduces lots of new interesting features and marks a big step forward in the development of our antivirus engine. The most important change is the introduction of scripted updates. Instead of transferring the whole cvd file at each update, only the differences between the latest cvds and the previous versions will be transferred. In case the local copy of the latest cvd is corrupted or the scripted update fails for some reason, freshclam will fallback to the old method. Similarly to cvd files, scripted updates are compressed and digitally signed and are already being distributed. They will dramatically reduce traffic on our mirrors and will allow us to release even more updates in the future. Another noticeable change is the new configuration syntax: you can now turn single options on and off, the old crude hack of "DisableDefaultScanOptions" is no longer required. Cosmetic changes apart, the 0.9x series introduces lots of new code, but some parts are not compiled in by default because they are not ready for production systems yet. You are encouraged to pass the --enable-experimental flag to ./configure when compiling ClamAV. The experimental code introduces many improvements in terms of detection rate and performances. If you find a bug, please take some time to report it on our bugzilla: Your help in testing the new code is really appreciated. The experimental code introduces many improvements in terms of detection rate and performances. RAR3, SIS and SFX archives support is finally available together with new unpackers and decryptors: pespin, sue, yc, wwpack32, nspack, mew, upack and others. Additionally, ClamAV now includes better mechanisms for scanning ELF, PDF and tar files. The email decoding has been improved to reduce both the memory requirements and the time taken to process attachments. As part of the Google Summer of Code program, we have introduced support for a new phishing signatures format that has proved very effective in detecting phishing emails. The ClamAV phishing module allows better and more generic detection of phishing emails by searching for URLs in email messages, and comparing the real site with the URL displayed to the user in the message. On the performance side, support for the MULTISCAN command has been implemented in clamd, allowing to scan multiple files simultaneously. Support for Sensory Networks' NodalCore acceleration technology ( is now available in ClamAV and will be compiled in if the ncore libraries are detected at compile time. NodalCore acceleration allows highly improved scan speeds on systems equipped with NodalCore cards.

The internal mail scanner now supports multipart/partial messages, and support for decoding non-standard mail files was greatly enhanced. clamav-milter by default uses libclamav and scans emails itself without the use of clamd. libclamav can now extract RFC2397 encoded data within HTML documents, block zip archives with modified information in local header, and scan HQX files. PE file structure rebuilding from compressed executables was improved. Important note to clamdwatch users: please upgrade to the latest version (contrib/clamdwatch) as soon as possible. -) libclamav: + major improvements in the mail scanning engine: o support for multipart/partial messages o improved support for non-standard quoted-printable attachments o in some situations it will try to guess a correct mode (e.g. a good type for an incorrect content-type, a best guess for an unknown encoding type, etc.) o handling of RFC822 comments in the commands (e.g.: Co(foo)ntent-Type: text/plain) o better recovery if memory softlimit is hit o new test code that decodes emails without parsing them first (must be enabled manually before compilation) + support for extracting RFC2397 encoded data within HTML documents + blocking of zip archives with modified information in local header + improved PE structure rebuilding from compressed executables + improved support for zip archives + support for Mac's HQX file format + stability and (minor) security fixes + a lot of minor improvements, including support for new platforms -) clamd: + new directive ExitOnOOM (stop the deamon when libclamav reports an out of memory condition) + new directives StreamMinPort and StreamMaxPort (port range specification for a stream mode) + support for passing of file descriptors -) clamdscan: + added support for --move and --remove -) clamav-milter: + by default uses libclamav to scan e-mails + new option --external (enables the use of clamd) + various optimisations -) freshclam: + the DNS mode is now enabled by default (no need for DNSDatabaseInfo in freshclam.conf) + --no-dns uses a If-Modified-Since method instead of a range GET + added support for AllowSupplementaryGroups -) sigtool: + new options --vba and --vba-hex (extract VBA/Word6 macros and optionally display the corresponding hex values; Word6 binary code will be disassembled) -) The list of third party programs with support for ClamAV is growing rapidly.

Please read the release notes for the candidate versions below. -- The ClamAV team ( 0.80rc4 ------- Improvements in this release include better JPEG exploit verification, faster base64 decoding, support for GNU tar files, updated on-access scanner, and others. -- The ClamAV team ( 0.80rc3 ------- This release candidate eliminates possible false positive alerts in UPX/FSG compressed files and clarifies behaviour of default actions in clamd and freshclam. We encourage users to take advantage of our new mirror structure. In order to download the database from the closest mirror you should configure freshclam to use where XY is your country code (see for the full list). Please add the following lines to freshclam.conf: DNSDatabaseInfo DatabaseMirror DatabaseMirror DNSDatabaseInfo enables database and software version verification through DNS TXT records, and the second database mirror acts as a fallback in case a connection to the first mirror fails for some reason. 0.80rc2 ------- This update fixes a serious bug in e-mail scanner. 0.80rc ------ The development version of ClamAV is ready for general testing! New mechanisms have already proved very nasty to Internet worms successfully protecting against the new versions R, S, T, U, V and W of the infamous Mydoom worm and detecting them as Worm.Mydoom.Gen before they were analysed and specific signatures added by the ClamAV database maintainers. That means servers running the new version of ClamAV have detected and blocked 100% of Mydoom attacks! New features in this release include: -) libclamav + Portable Executable analyser (CL_SCAN_PE) featuring: o UPX decompression (all versions) o Petite decompression (2.x) o FSG decompression (1.3, 1.31, 1.33) o detection of broken executables (CL_SCAN_BLOCKBROKEN) + new, memory efficient, pattern matching algorithm (multipattern variant of Boyer-Moore) - it's now primary matcher and Aho-Corasick is only used for regular expression extended signatures + new signature format with advanced target type and offset specification + support for MD5 based signatures + extended regular expression scanner + added support for MS cabinet files + added support for CHM files + added support for POSIX tar archives + scanning inside PowerPoint documents + HTML normaliser with support for decoding of MS Script Encoder code + great improvements in e-mail scanner (now handles even more worm tricks) + new method of mail files detection + all e-mail attachments are now scanned (previously only the first ten attachments were scanned) + added support for scanning URLs in e-mails (CL_SCAN_MAILURL) + detection of Worm.Mydoom.M.log + updated API (still backward compatible but please consult clamdoc.pdf (Section 6) and adapt your software) -) clamd + new directive ScanHTML (enables HTML normalisator and ScrEnc decoder) + new directive ScanPE (win32 executable analyser and decompressor) + new directive DetectBrokenExecutables (try to detect broken executables and mark them as Broken.Executable) + new directive MailFollowURLs (try to download and scan files from URLs in mails.

Wear them and virus writers will stay away from you :-) A quarter out of every dollar profited from the sale of these shirts will go to the ClamAV project. Visit and click on ClamAV logo! -- The ClamAV team ( 0.75 ---- This release fixes detection of e-mails generated by Worm.Mydoom.I. Important notice for people using ClamAV 0.60: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Our logs show that there is still a small percentage of ClamAV 0.60 installations updating their database. ClamAV 0.60 was released on July 29th, 2003 and it was the last release to use the old database format. Starting from version 0.65, released on November 12nd, ClamAV uses a new database format, which is compressed and digitally signed. We have been distributing the database in both formats till now, but we plan to drop support for ClamAV 0.60 on September 1st. We encourage _all_ users to upgrade to the latest release available. People running an old version of ClamAV are missing many viruses and may experience stability problems. On non-production systems you can try the latest development version. The new engine not only speeds up the scanning process but also limits memory usage by about 8 MB ! It's able to scan new formats, including CAB, CHM, UPX, HTML (normalisation), PowerPoint macros and can detect annoying e-mails with empty attachments generated by new Bagle variants. -- The ClamAV team ( 0.74 ---- Bugfixes in this version include crashes with multipart/mixed messages and corrupted OLE2 and Zip files. Improvements include various optimisations of mail scanning and clamav-milter and clamdscan behaviour. New members of our "3rd party software" list: + MyClamMailFilter an e-mail filter for procmail (written in C) + clamaktion scan files from the right-click Konqueror menu + QMVC Qmail Mail and Virus Control + pyclamav Python binding for ClamAV + FETCAV Front End To Clam AntiVirus based on Xdialog + Famuko an on-access scanner working in a userspace + SoftlabsAV a generic anti-virus filter for procmail Japanese users can take an advantage of the new ClamAV related site: and join the clamav-jp-users mailing list. -- The ClamAV team ( 0.73 ---- This version fixes memory management problems in the OLE2 decoder and improves mail scanning. Because of the rapid ClamAV development the team encourages users to help in testing new features: Thank you for using ClamAV ! -- The ClamAV team ( 0.72 ---- Major bugfixes in this release include crashes with corrupted BinHex messages and some Excel documents. Protection against archive bombs (not fully functional since 0.70) was improved and a number of other improvements were made. -- The ClamAV team ( 0.71 ---- This release fixes all bugs found in 0.70 and introduces a few new features - the noteworthy changes include: -) libclamav: + support nested OLE2 files + support Word6 macro code + ignore popular file types (media, graphics) + support compress.exe (SZDD) compression (test/test.msc) + improve virus detection in e-mails -) clamscan: + automatically decide (by comparing daily.cvd version numbers) which database directory (hardcoded or clamav.conf's one) to use + support compression ratio feature (--max-ratio) + allow regular expressions in --[in|ex]clude + do not overwrite old files in a quarantine directory but add a numerical extension to new files + respect --tempdir in libclamav + fix access problem when calling external unpackers in a superuser mode + fix file permission corruption with --deb in a superuser mode -) clamd + support log facility specification in syslog's style (LogFacility) + new directive LeaveTemporaryFiles (Debug no longer leaves temporary files not removed) -) clamav-milter: + include the virus name in the 550 rejection + support user defined template for virus notifications (--template-file) + sort quarantine messages by date + improve thread management + add X-Virus-Scanned and X-Infected-Received-From: headers + improve load balancing (when using remote servers with --server) + send 554 after DATA received, not 550 + save PID (--pidfile) -) documentation: + German clamdoc.pdf translation (Rupert Roesler-Schmidt and Karina Schwarz, uplink coherent solutions, + new Japanese documentation (Masaki Ogawa) -- The ClamAV team ( 0.70 ---- The two major changes in this version are new thread manager in clamd and support for decoding MS Office VBA macros. Both of them have been implemented by Trog. Besides, there are many improvements and bugfixes (all listed in ChangeLog), a short summary: -) clamd + new thread manager (with better SMP support) + on-access scanning now also available on FreeBSD (with Dazuko 2.0) + new directive ArchiveBlockEncrypted + new directive ReadTimeout (replaces ThreadTimeout) + handle SIGHUP (re-open logfile) and SIGUSR2 (reload database) + respect TCPAddr in stream scanner -) clamav-milter: + TCPWrappers support -) libclamav: + support MS Office documents (OLE2) and VBA macro decoding + support encrypted archive detection + new flags: CL_OLE2, CL_ENCRYPTED (see clamdoc.pdf, Section 6.1) + improve virus detection in big files + improve support for multipart, bounce and embedded RFC822 messages + improve RAR support + include backup snprintf implementation -) clamscan: + new option: --block-encrypted -) freshclam + new option: --pid, -p (write pid file if run as daemon) + handle SIGHUP (re-open logfile), SIGTERM (terminate with log message), SIGALRM and SIGUSR1 (wake up and check mirror) + fix bug with -u and -c handling -) contrib + windows clamd client now available with source code -) documentation: + new Polish documentation on ClamAV and Samba integration + official documentation updated Special thanks to Dirk Mueller <mueller*> for his code review, many bugfixes and cleanups. Thanks to the help of many companies (clamdoc.pdf: Section 2.10, we have 49 very fast and reliable virus database mirrors in 22 regions and the number is still growing. As of March 2004 we attempt to redirect our users to the closest pool of mirrors by looking at their ip source address when they try to resolve Our DNS servers can answer with a CNAME to:,, or Our advanced push-mirroring mechanism (maintained by Luca Gibelli) allows database maintainers to update all the mirrors in less than one minute ! There will be no major feature enhancements in the 0.7x series. Our work will be concentrated on a new scanning engine and preliminary heuristics - please help us and test CVS snapshots from time to time.

We strongly encourage users to install the 0.70-rc version (released today). 0.67 ---- This release fixes a memory management problem (platform dependent; can lead to a DoS attack) with messages that only have attachments (reported by Oliver Brandmueller). It also contains patches for a few problems found in 0.66 and has better Cygwin support. 0.66 ---- This version is a response to the "clamav 0.65 remote DOS exploit" information published on popular security-related mailing lists. Unfortunately we had not been contacted by the author before he published that and had to release this (unplanned) package very quickly (it should be mentioned that CVS version was not vulnerable to the exploit). Untested code has been disabled also the Dazuko support is temporarily not available (if you really need it please use a CVS version or wait for a next stable release). Other noteworthy changes: -) clamd: + fixed database timestamp handling (and a double reload problem reported by Alex Pleiner and Ole Stanstrup) + new directive: ArchiveMaxCompressionRatio + new command: SESSION (starts a clamd session and allows to do multiple commands per TCP session) + new directives: TemporaryDirectory, LogClean (Andrey V.

The signature was published by Diego d'Ambra in the daily update 105, 26-Jan-2004 20:23 GMT and we were at least two hours faster than "big" AV vendors: clamav-devel is finally able to decode OLE2 (Microsoft Office) files and decompress VBA streams ! The code is developed by Trog, official ClamAV developer. Also we're testing new clamd implementation that will solve several important problems (especially that "Time out" related). Please help us and test the latest CVS version. The virus database now contains more than 20.000 signatures ! On January 8, Denis De Messemacker (who joined our team 3 months ago) added signatures for about 7700 new viruses. Also special thanks go to Tomasz Papszun for his hard work on daily submissions and forcing us to keep ClamAV quality on the highest possible level. New mirroring mechanisms. Luca Gibelli (ClamAV) and mirror administrators (22 sites,, please see clamdoc.pdf for a complete mirror information) are converting mirrors to new "push mirroring" method. It uses advanced techniques to ensure all the mirrors are up to date.
