A product providing clamav antivirus integration for Plone Dexterity content types

Project description

A product providing clamav antivirus integration for Plone sites with AT and Dexterity content types. It does that by defining a validator which could be used with any content type that uses File, Image or Named field(s). The open-source Clam Antivirus is supported which is available for all platforms.


  • To start, you need to have clamd running on some host accessible by your instances. collective.clamav supports either UNIX socket connections or remote connections.

  • Install collective.clamav and setup the host & port or the path to the clamd socket in the control panel (default is a network connection to clamd listening on localhost at port 3310). By default Files and Images are going to be checked for viruses when added or updated.

Adding anti-virus protection to non-ATFile based content

If you want to add anti-virus protection to your custom AT content types add the isVirusFree validator to your FileField(s). For instance:

  validators = (('isNonEmptyFile', V_REQUIRED),
                ('isVirusFree', V_REQUIRED),),
  widget = FileWidget(label=u'File'),

If you create custom Dexterity content types add only the necessary import statement to the module and all plone.namedfile fields were automatically scaned:

from Products.validation import V_REQUIRED)


Install collective.clamav by adding it to your buildout:



eggs =

and then running bin/buildout



Some code was shamelessly borrowed from pyClamd and collective.ATClamAV:
