Clam AntiVirus is an open source (GPLv2) anti-virus toolkit, designed especially for e-mail scanning on mail gateways. It provides a number of utilities including a flexible and scalable multi-threaded daemon, a command line scanner and advanced tool for automatic database updates. The core of the package is an anti-virus engine available in a form of shared library.
ClamAV is licensed under the GNU General Public License, Version 2.
Clam AntiVirus is highly cross-platform. The development team cannot test every OS, so we have chosen to test ClamAV using the two most recent Long Term Support (LTS) versions of each of the most popular desktop operating systems. Our regularly tested operating systems include:
The following minimum recommended system requirements are for using
clamdscan binaries with the standard ClamAV signature database provided by Cisco.
Minimum recommended RAM:
Minimum recommended CPU:
Minimum available hard disk space required:
For the ClamAV application we recommend having 5 GB of free space available. This recommendation is in addition to the recommended disk space for each OS.
Please note: The tests to determine these minimum requirements were performed on systems that were not running other applications. If other applications are being run on the system, additional resources will be required in addition to our recommended minimums.
If you have a trouble installing or using ClamAV try asking on our mailing lists. There are four lists available:
You can subscribe and search the mailing list archives here.
Alternatively you can try asking on the
#clamav IRC channel - launch your favourite irc client and type:
/server irc.freenode.net /join #clamav
If you prefer Discord over IRC, join the ClamAV Discord chat server. The ClamAV Discord #general, and #irc-verbose channels are bridged with the #clamav IRC channel using a pair of bots to relay messages.
If you’ve got a virus which is not detected by the current version of ClamAV using the latest signature databases, please submit the sample for review at our website:
Likewise, if you have a benign file that is flagging as a virus and you wish to report a False Positive, please submit the sample for review at our website:
