Apr 07, 2021 ClamAV can be found in the apt repository. Run this command to install ClamAV: apt-get install clamav. If you need clamd, you may also want to run: apt-get install clamav-daemon. For the stable release, the packages are updated via the StableUpdates mechanism. You won’t even notice it working away in the background – but threats to your Mac will, as virus definitions are constantly updated. You and your Mac Whether you’re a home user, business user or education user, ClamXAV provides effective malware protection on a single Mac or an entire network. Clamav scans for windows viruses (only) Using clam on desktop os x is pretty odd, but if it makes you feel safe. It is also used (its primary use) on linux servers scanning email for windows.

Free & Best Antivirus for Linux servers is ClamAV. Email scanning, Web scanning and End point security are the few features which help secure your VPS, VDS or Dedicated Linux server. CentOS provides security such that threats are minimal but user actions can expose your server to tojans or virus. ClamAVs engine is capable of detecting 1 million viruses, worms, malware and other threads as claimed by ClamAV itself.

How to install ClamAV on Linux server or centOS

Step by step tutorial to install ClamAV on centOS
Step 01 : ClamAV is not available on centOS default repo, you need to install special package ‘epel’ stands for Extra Packages for Enterprise Linux
yum install -y -q epel-release
Step 02 : Download and install clamAV from epel package

yum --enablerepo=epel -y -q install clamav-server clamav-data clamav-update clamav-filesystem clamav clamav-scanner-systemd clamav-devel clamav-lib clamav-server-systemd

Step 03 : update config file to replace examples

sed -i -e 's/^Example/#Example/' /etc/clamd.d/scan.confsed -i -e 's/^Example/#Example/' /etc/freshclam.confsed -i 's/^#LocalSocket /run/clamd.scan/clamd.soc/LocalSocket /run/clamd.scan/clamd.soc/' /etc/clamd.d/scan.conf

Step 04 : Update ClamAV database
freshclam
Step 05: start and enable the services

systemctl start clamav-freshclam.servicesystemctl enable clamav-freshclam.servicesystemctl enable clamd@scansystemctl start clamd@scan

Memorandum : Building ClamAV® on Mac OS X 10.4 through macOS 11.x Big Sur

Building ClamAV® on Mac OS X 10.4 through macOS 11.x Big Sur

I'm running ClamXav Sentry as 'launch agent' with ClamAV antivirus scanning engine of my own custom build.
I've tested for building ClamAV (from version 0.90.x to version 0.103.x) on Mac OS X 10.4 through macOS 11.x Big Sur.
I'm running the latest stable release ClamAV 0.103.2 on macOS 11.2 Big Sur now.
ClamAV 0.103.2 is available on the Download page of ClamavNet, and the release note is here!
When you want to build ClamAV-devel from the Git sources, autotools are now requied.
For further information, see the following section:
'How to install ClamAV®-devel from the Git sources on macOS'.
CMake is now the preferred build system on ClamAV 0.104.x
The Autotools build system is still available but is expected to be removed in the near future.
For further information, see the following section:
'How to build ClamAV® with CMake Build System on macOS'.

This memorandum contains as below:
・ Memorandum 1: Building ClamAV 0.103.x on OS X 10.10 Yosemite through macOS 11.x Big Sur
・ Memorandum 2: Building ClamAV 0.99.x on OS X 10.10, 10.11, 10.12 and macOS 10.13 High Sierra
・ Memorandum 3: Building ClamAV 0.98.7 on OS X 10.10 Yosemite and 10.11 El Capitan
・ Memorandum 4: Building ClamAV on Mac OS X 10.4 (Intel)
・ Memorandum 5: Building ClamAV on Mac OS X 10.4 (PPC)
・ Memorandum 6: Building ClamAV on Mac OS X 10.6 through OS X 10.9 Mavericks
・ Memorandum 7: Running clamd and freshclam as daemon
・ Memorandum 8: Running ClamXav Sentry as 'launch agent' on Mac OS X 10.6 and later…
・ Memorandum 9: Update ClamXav's own Virus Database and running RunFreshclam as daemon
・ Memorandum 10: Running ClamXAV version 2.18.x with B.Y.O. ClamAV antivirus scanning engine

Memorandum 1: Building ClamAV 0.103.x on OS X 10.10 Yosemite through macOS 11.x Big Sur

Building ClamAV 0.103.x on OS X 10.10 Yosemite through macOS 11.x Big Sur

1. Requirements to build ClamAV 0.103.x is very much the same as building ClamAV 0.102.x.
2. Requirements to build ClamAV 0.102.x are almost the same as building ClamAV 0.101.x. and ClamAV 0.100.x.
The differences are as follows:
LLVM current version is 10.0.x, though ClamAV 1.02.x supports only LLVM =< 3.6.x.
The ClamAV team is not maintaining repackaged LLVM now, and they may drop the repackaged LLVM entirely
and deprecate support for system-installed LLVM in favor of the bytecode interpreter.
So LLVM Libraries are not necessarily required to build ClamAV 0.102.x, I think.
I am now configuring ClamAV 0.102.x to disable LLVM as follows:
Of course you can configure ClamAV 0.102.x to enable LLVM as before:
3. Requirements to build ClamAV 0.102.x and ClamAV 0.101.x are almost same as before.

The following are required as discussed in detail below.
・ PCRE Libraries
・ OpenSSL Libraries
・ LLVM Libraries (Only when enabling LLVM)

4. Differences

The default behavior for clam to link LLVM has been changed dynamically instead of statically.
Thus making ClamAV 0.100.x fails with an error:
To build ClamAV 0.100.x enabling the LLVM Just-In-Time compiler for executing bytecode signatures,
use this configuration:
or simply use this configuration to disable LLVM Just-In-Time compiler:

Memorandum 2: Building ClamAV 0.99.x on OS X 10.10, 10.11, 10.12 and 10.13 High Sierra

Building ClamAV 0.99.x on OS X 10.10, 10.11, 10.12 and 10.13 High Sierra

ClamAV 0.99.x contains major new features such as YARA rules, PCRE - Perl Compatible Regular Expressions and so on.
To support YARA and ClamAV logical signatures, the Perl Compatible Regular Expressions (PCRE) library is required.
If PCRE isn't installed on your system, you will get a warning message like this while running freshclam.
1. To ensure the PCRE library:
1) Install PCRE - Perl Compatible Regular Expressions.,

2) When compiling ClamAV 0.99.x, it fails with an error:

3) To avoid this failure, simply set CPPFLAGS:
4) And add this configuration option when configuring ClamAV: --with-pcre=/usr/local/pcre2.

2. To compile ClamAV 0.99.x on OS X 10.10 Yosemite or on OS X 10.11 El Capitan and macOS 10.12 Sierra,

in addition to the PCRE library;
1) LLVM Library is required on OS X 10.10 Yosemite.
2) LLVM Library and LibreSSL are required on OS X 10.11 El Capitan and macOS 10.12 Sierra.
Please readMemorandum 3 to learn more, and…
3) Install LLVM Library Binaries.
4) Install LibreSSL.

3. Configure ClamAV 0.99.x on OS X 10.10 Yosemite as follws:
4. Configure ClamAV 0.99.x on OS X 10.11 El Capitan and macOS 10.12 Sierra as follws:

Memorandum 3: Building ClamAV 0.98.7 on OS X 10.10 Yosemite and 10.11 El Capitan

Built-in LLVM of ClamAV 0.98.7 and 0.99.x are not compatible with GNU C++ on OS X 10.10 Yosemite and 10.11 El Capitan.
So ClamAV 0.98.7 and 0.99.x built on OS X 10.10 Yosemite or on OS X 10.11 El Capitan have major issues:
- Clamd crashes repeatedly throwing 'Segmentation Fault: 11'
- Clamscan also crashes and fails to scan…
- Freshclam fails to load new database logging:

These problems can be avoided by installing official LLVM.
Versions of LLVM beyond 3.6 seem not to be currently supported in ClamAV, so you should install LLVM 3.6.2.
