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.

----
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.

list of changes.
--
The ClamAV team (http://www.clamav.net/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 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)
For more details, please refer to http://www.clamav.net/press/0.94-WhatsNew.pdf
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.

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

Scan engine improvements were made. 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

----
Stable version. Please read the release notes for the candidate versions below.
--
The ClamAV team (http://www.clamav.net/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 (http://www.clamav.net/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 db.XY.clamav.net where XY is your country code (see
http://www.iana.org/cctld/cctld-whois.htm for the full list). Please add
the following lines to freshclam.conf:
DNSDatabaseInfo current.cvd.clamav.net
DatabaseMirror db.XY.clamav.net
DatabaseMirror database.clamav.net
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

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. BE CAREFUL! DO NOT ENABLE IT ON LOADED MAIL SERVERS)
+ new directive ArchiveBlockMax (archives that exceed limits will be
marked as viruses)
+ clamav.conf was renamed clamd.conf
-) clamscan
+ mail files are scanned by default, use --no-mail to disable it
+ new option --no-html (disables HTML normalisator)
+ new option --no-pe (disables PE analyser)
+ new option --detect-broken
+ new option --block-max
+ new option --mail-follow-urls (download and scan files from URLs in mails)
-) clamdscan

+ improved template file format
+ quarantined file names now contain virus names
+ initial support for SESSION mode of clamd
-) freshclam:
+ new directive DNSDatabaseInfo that enables ultra lightweight version

Special thanks to aCaB for his work on UPX, FSG and Petite decompressors.
Thanks to good reaction times on new threats ClamAV was awarded as best
security tool for 2004 by Linux Journal: "...With this year's outbreak of
e-mail worms for non-Linux platforms, ClamAV has been getting quite a workout,
and Linux admins on mailing lists report that database update times are keeping
up with or beating the proprietary alternatives." Thanks!

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.

Special thanks to Dirk Mueller for his code review,
many bugfixes and cleanups.
Thanks to the help of many companies (clamdoc.pdf: Section 2.10,
http://www.clamav.net/mirrors.html) 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
database.clamav.net. Our DNS servers can answer with a CNAME to:
db.europe.clamav.net, db.america.clamav.net, db.asia.clamav.net or
db.other.clamav.net. 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 are happy to announce new programs with support for ClamAV (all of them
have been reviewed by our team - more info in the documentation and
on our website: http://www.clamav.net/download/third-party-tools):

News:
ClamAV was the first anti-virus protecting against Worm.SCO.A (aka MyDoom.A) !
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:
http://sourceforge.net/mailarchive/forum.php?thread_id=3764826&forum_id=34654
http://www.pcwelt.de/news/viren_bugs/37278/4.html
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, http://www.clamav.net/mirrors.html, 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.

0.60
----
Hello again...
This is a new, (very?) stable release of Clam AntiVirus. 0.60 was developed
and stabilized for over seven months and many people had contributed to the
final release. This version introduces many enhancements and a new program:
clamav-milter written by ClamAV developer Nigel Horne. This is a mail scanner
for Sendmail/milter written entirely in C, which uses clamd for virus scanning.
Clamav-milter and clamd duet is a powerful solution for systems where high
performance is required. Please check clamdoc for more detail.
Many people get confused with ClamAV database status because of
the OpenAntiVirus update information at:
http://openantivirus.org/latest.php
(last update at 17 October, 2002). The ClamAV virus database contains
the OAV database (with some signatures fixed or removed) but we
develop it independently of the OAV project. Our database is updated
frequently (on average 4-5 times a week). You can help (or join) us -
will find some basic but useful instructions at
http://clamav.elektrapro.com/doc/signatures.pdf
News from ClamAV world:
-) New email address for virus submitting: virus@clamav.elektrapro.com
You don't need to encrypt a virus sample, but if your system doesn't allow
you to send infected files just put it into an encrypted zip archive
(password: virus)
Special thanks to Nicholas Chua, Diego D'Ambra, Hrvoje Habjanic, Nigel Kukard
and Chris van Meerendonk for a big number of samples submitted.
-) New mailing list: virusdb@clamav.elektrapro.com
After each update an email with subject "[clamav-virusdb] Update" and a list
of viruses added is sent to it. You can set up a procmail rule for freshclam
to react on such a mails (and update the database just after an update).
-) New official mirrors:
+ clamav.ozforces.com: database mirror updated manually (thanks to
Andrew )
+ clamav.essentkabel.com: full (automatic) mirror of clamav.elektrapro.com
(thanks to Chris van Meerendonk )
+ clamav.linux-sxs.org: database mirror - rsync from clamav.ozforces.com
(thanks to Douglas J Hunley )
Freshclam will automatically use them when the main server is not
accessible.
-) Official port in FreeBSD available ! (maintained by Masahiro Teramoto
)
-) Unofficial port for OpenBSD is available at:
http://www.activeintra.net/openbsd/article.php?id=5
(maintained by Flinn Mueller )
-) there are many new programs that use ClamAV, eg. mod_clamav (Apache
virus scanning filter), clamdmail or Sagator. You will find more
info in clamdoc.
Changes:
-) libclamav:
+ fixed buffer overflow in unrarlib (patch by Robbert Kouprie
)
+ various mbox code updates (fixed memory leak; added support for decoding
viruses sent in message bodies, detection of viruses that put their
payloads after the end of message marker (thanks to Stephen White
for the bug report and useful CGI tools);
+ zziplib updated to 0.10.81 (some problems with older version were reported
by Martin Schitter)
+ direct scanning of mbox/maildir files (new directive CL_MAIL)
+ file scanner optimization (patch by Hendrik Muhs
)
+ bzip2 support
+ faster detection of malformed Zip archives (eg. 'Zip of Death'), they are
reported as a viruses
+ fixed strcasecmp() compile problem in zziplib on Free/NetBSD and others
-) clamd:
+ fixed descriptor leak in directory scanner - it was causing random
clamd crashes and locks, especially on highly loaded servers. Reported
by Kristof Petr .
+ fixed crash with archive scanning on BSD (increased thread stack size)
(Nigel Horne)
+ fixed CONTSCAN command (used by clamdscan) - it had archive support
disabled (hardcoded)
+ fixed SelfCheck option (there was a logic bug, and the option was
disabled) it now checks a databases time stamps and reloads them
if needed.
+ fixed possible writing to undefined descriptors (bug found by
Brian May )
+ new STREAM command (scanning data on socket) and directives:
StreamSaveToDisk (save stream to disk to allow scanning within archives),
StreamMaxLength. This option allows scanning data on socket (might be
sent from another host), currently only clamav-milter uses this.
+ new ScanMail directive for scanning into mbox/Maildir files
+ new directive: ArchiveLimitMemoryUsage (limit memory usage with bzip2)
+ new directive: AllowSupplementaryGroups (feature requested by Exiscan
users)
+ syslog support (LogSyslog) (patch by Hrvoje Habjanic
)
+ fixed parser segfault with extra space between option and argument
in config file (Magnus Ekdahl )
-) clamscan:
+ fixed --remove option (didn't work when the file was scanned with an
internal unpacker) (patch by Damien Curtain )
+ --move option for moving infected files into a specified directory
(by Damien Curtain )
+ --mbox enables a direct support for mbox files
(ex. clamscan --mbox /var/spool/mail)
+ fixed --log (-l) option
+ fixed -i option (patch by Magnus Ekdahl )
+ enabled default archive limits (max-files = 500, max-size = 10M,
max-recursion = 5)
+ use arj instead of non-free unarj (patch by Magnus Ekdahl)
+ use unzoo instead of non-free zoo (patch by Magnus Ekdahl)
+ removed thread support
freshclam:
+ mirror support (implemented by Damien Curtain )
+ --proxy-user: proxy authorization support (implemented by Gernot Tenchio
)
+ new options --on-error-execute, --on-update-execute
(ex. freshclam -d -c 6 --on-error-execute "sendsms 23332243 Can't
update virus database"). Idea by Douglas J Hunley
configure:
+ --disable-cr (don't link with C reentrant library (needed on some newer
versions of OpenBSD))
-) Enhanced AIX (thanks to Mike Loewen ) and
Tru64 support (thanks to Christophe Varoqui )
-) documentation:
+ included how-to in Portugese by Alexandre de Jesus Marcolino
+ clamdoc.pdf and system manual updates
Many thanks to Luca 'NERvOus' Gibelli from ElektraPro for his support,
to Ken McKittrick from USA DataNet for a fully accessible FreeBSD box and
to mailing list subscribers for a constructive discussions.

----
Many major changes this time...
-) libclamav:
+ fixed segfault with some strange zip archives (there is a bug in zziplib,
libclamav contains a work around for it) (the problem was reported by
Oliver Paukstadt )
+ engine improvements (better support for a detection of new viruses,
limited memory usage (consumes ~ 5 Mb now))
+ mbox code updated and moved into the library: fixed core dump when an
embedded message includes a mime header with the line Content-Type:
without specifying the type of content, fixed (theoretical) memory leak,
support for multipart/report messages, fixed bug causing some formats to
fail to scan) (Nigel)
-) clamd:
+ new commands: CONTSCAN (it doesn't stop scanning even when virus is
found), VERSION
+ disable logging of a unnecessary time stamps with LogTime when
LogVerbose isn't used (patch by Ed Phillips )
-) freshclam:
