0.99
----
ClamAV 0.99 contains major new features and changes. YARA rules,
Perl Compatible Regular Expressions, revamped on-access scanning
for Linux, and other new features join the many great features of ClamAV:
- Processing of YARA rules(some limitations- see signatures.pdf).
- Support in ClamAV logical signatures for many of the features
added for YARA, such as Perl Compatible Regular Expressions,
alternate strings, and YARA string attributes. See signatures.pdf
for full details.
- New and improved on-access scanning for Linux. See the recent blog
post and clamdoc.pdf for details on the new on-access capabilities.
- A new ClamAV API callback function that is invoked when a virus
is found. This is intended primarily for applications running in
all-match mode. Any applications using all-match mode must use
the new callback function to record and report detected viruses.
- Configurable default password list to attempt zip file decryption.
- TIFF file support.
- Upgrade Windows pthread library to 2.9.1.
- A new signature target type for designating signatures to run
against files with unknown file types.
- Improved fidelity of the "data loss prevention" heuristic
algorithm. Code supplied by Bill Parker.
- Support for LZMA decompression within Adobe Flash files.
- Support for MSO attachments within Microsoft Office 2003 XML files.
- A new sigtool option(--ascii-normalize) allowing signature authors
to more easily generate normalized versions of ascii files.
- Windows installation directories changed from \Program Files\Sourcefire\
ClamAV to \Program Files\ClamAV or \Program Files\ClamAV-x64.
PLEASE NOTE: If you are using clamd on-access scanning or have applications
using all-match mode, you will want to review the changes and make any necessary
adjustments before using ClamAV 0.99. Users of windows binaries need to be
aware of the change of installation directories.

0.98.5
------
Welcome to ClamAV 0.98.5! ClamAV 0.98.5 includes important new features
for collecting and analyzing file properties. Software developers and
analysts may collect file property meta data using the ClamAV API for
subsequent analysis by ClamAV bytecode programs. Using these features
will require that libjson-c is installed, but otherwise libjson-c is not
needed.
Look for our upcoming series of blog posts to learn more about using the
ClamAV API and bytecode facilities for collecting and analyzing file
properties.
ClamAV 0.98.5 also includes these new features and bug fixes:
- Support for the XDP file format and extracting, decoding, and
scanning PDF files within XDP files.
- Addition of shared library support for LLVM versions 3.1 - 3.5
for the purpose of just-in-time(JIT) compilation of ClamAV
bytecode signatures. Andreas Cadhalpun submitted the patch
implementing this support.
- Enhancements to the clambc command line utility to assist
ClamAV bytecode signature authors by providing introspection
into compiled bytecode programs.
- Resolution of many of the warning messages from ClamAV compilation.
- Improved detection of malicious PE files.
- Security fix for ClamAV crash when using 'clamscan -a'. This issue
was identified by Kurt Siefried of Red Hat.
- Security fix for ClamAV crash when scanning maliciously crafted
yoda's crypter files. This issue, as well as several other bugs
fixed in this release, were identified by Damien Millescamp of
Oppida.
- ClamAV 0.98.5 now works with OpenSSL in FIPS compliant mode.
Thanks to Reinhard Max for supplying the patch.
- Bug fixes and other feature enhancements. See Changelog or
git log for details.

0.98.2
------
Here are the new features and improvements in ClamAV 0.98.2:
- Support for common raw disk image formats using 512 byte sectors,
specifically GPT, APM, and MBR partitioning.
- Experimental support of OpenIOC files. ClamAV will now extract file
hashes from OpenIOC files residing in the signature database location,
and generate ClamAV hash signatures. ClamAV uses no other OpenIOC
features at this time. No OpenIOC files will be delivered through
freshclam. See openioc.org and iocbucket.com for additional information
about OpenIOC.
- All ClamAV sockets (clamd, freshclam, clamav-milter, clamdscan, clamdtop)
now support IPV6 addresses and configuration parameters.
- Use OpenSSL file hash functions for improved performance. OpenSSL
is now prerequisite software for ClamAV 0.98.2.
- Improved detection of malware scripts within image files. Issue reported
by Maarten Broekman.
- Change to circumvent possible denial of service when processing icons within
specially crafted PE files. Icon limits are now in place with corresponding
clamd and clamscan configuration parameters. This issue was reported by
Joxean Koret.
- Improvements to the fidelity of the ClamAV pattern matcher, an issue
reported by Christian Blichmann.
- Opt-in collection of statistics. Statistics collected are: sizes and MD5
hashes of files, PE file section counts and section MD5 hashes, and names
and counts of detected viruses. Enable statistics collection with the
--enable-stats clamscan flag or StatsEnabled clamd configuration
parameter.
- Improvements to ClamAV build process, unit tests, and platform support with
assistance and suggestions by Sebastian Andrzej Siewior, Scott Kitterman,
and Dave Simonson.
- Patch by Arkadiusz Miskiewicz to improve error handling in freshclam.
- ClamAV 0.98.2 also includes miscellaneous bug fixes and documentation
improvements.

0.98.1
------
ClamAV 0.98.1 provides improved support of Mac OS X platform, support for new file types, and
quality improvements. These include:
- Extraction, decompression, and scanning of files within Apple Disk Image (DMG) format.
- Extraction, decompression, and scanning of files within Extensible Archive (XAR) format.
XAR format is commonly used for software packaging, such as PKG and RPM, as well as
general archival.
- Decompression and scanning of files in "Xz" compression format.
- Recognition of Open Office XML formats.
- Improvements and fixes to extraction and scanning of ole formats.
- Option to force all scanned data to disk. This impacts only a few file types where
some embedded content is normally scanned in memory. Enabling this option
ensures that a file descriptor exists when callback functions are used, at a small
performance cost. This should only be needed when callback functions are used
that need file access.
- Various improvements to ClamAV configuration, support of third party libraries,
and unit tests.
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 specify
a '*' (wildcard) 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 chains 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 prefixed 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.

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.

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:
https://wiki.clamav.net/Main/UpgradeNotes095. 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
http://safebrowsing.clamav.net.
- 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.

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 www.clamav.net
where our users will be able to monitor the latest threats. You can help us
by enabling SubmitDetectionStats in freshclam.conf.

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)
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.

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: http://bugs.clamav.net.
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
(http://www.clamav.net/nodalcore/) 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.
Detailed list of changes:
-) libclamav:
+ New unpacker for RAR3, RAR2 and RAR1
+ Rewritten unpackers for Zip and CAB files
+ Support for RAR-SFX, Zip-SFX and CAB-SFX archives
+ New PE parsing model:
- Accurate virtual and raw size and offset calculations
- Proper parsing of executables with weird/handcrafted/uncommon headers
- Proper handling (or skipping) of ghost sections at various places in the
code
- Rebuild improvements for various unpackers
- Adjusted alignment on rebuilt executables
- Proper handling of out of sections offsets
- Broken exe detection now mimics the XPSP2 loader
- Lots of misc improvements and fixes
+ Support for PE32+ (64-bit) executables
