7.0.13+ This plugin can only be used with Xima® Formcycle Version 7.0.13 or higher.

Plugin-Download (requires login)

With the free ClamAV plugin for Xima® Formcycle it is possible to scan uploaded files for viruses. For this purpose, this plugin establishes a connection to a ClamAV daemon service via TCP.


Immediate virus scan
Each file is scanned immediately after upload.

The used ClamAV-daemon service can neither be configured nor started by this plugin.


The installation of the plugin has to be carried out via the interface of plugins provided for this purpose. Only the corresponding jar file has to be installed.

  The ClamAV plug-in scans files in backend and fronted. To be always available to all users it is advisable to install the plugin as a system plugin. This also avoids possible problems with double-used ports and enables a central configuration.

Plugin configuration

After saving, a ping test is automatically performed. If this fails, a message will be displayed. In this case all uploads in the backend or in the form will be marked as faulty - the plugin should be deactivated first and a working connection should be established.

If no connection can be established to the specified host, this message is displayed.

The following configuration parameters exist:

host (Required)
Default value: Specifies the IP address of the ClamAV-daemon service to be used. The default value is and thus uses a local ClamAV-daemon service.
port (Required)
Default value: 3310. Specifies the port of the ClamAV-daemon service to use. The default value should only be changed if this port is not available.
If the value stream is entered here (default value), the data of the file to be checked will be transferred directly to the ClamAV-daemon service. If the value path is entered here, scanning is done directly on the path - whereby the ClamAV-daemon service must have root rights for this.

ClamAV is intended to run on Linux-based servers. Therefore, we cannot guarantee any other support.

Configuration ClamAV

The following section discusses installation and configuration of ClamAV. Our recommended scenario is to install Xima® Formcycle and the ClamAV-daemon service on the same server.


To install ClamAV on a server, the following commands should be entered on the server.

ClamAV is the program that can scan files for viruses and is required for the use of ClamAV-daemon.

Update the package list:
 sudo apt-get update 
Install ClamAV and ClamAV-daemon:
 sudo apt-get install clamav clamav-daemon -y 

Update the virus signature database

freshclam is automatically installed with ClamAV and is used to update the virus signature database.

Terminate the automatic freshclam process:
 sudo systemctl stop clamav-freshclam 
Manually update virus signature database:
 sudo freshclam 

Configuration ClamAV-daemon

ClamAV-daemon is the process running in the background on the server, which is addressed for the virus scan. This is done via TCP and must be configured accordingly.

For this purpose, the configuration file under:  /etc/clamav/clamd.conf  should be adapted.

Open the configuration file:

 sudo nano /etc/clamav/clamd.conf 

Use the arrow keys to navigate to the end of the file.

Add TCPAddr 
Add TCPSocket 3310 

Specify root rights for ClamAV-daemon
To do this, the row User clamav has to be changed to User root in this file.

Now you can save and exit with Ctrl + X. Confirm with Y and the Enter key.

Starting the ClamAV-daemon Service

Now the service can be started.

Start the ClamAV-daemon Service:
 sudo systemctl start clamav-daemon.service 

Checking the availability of the service

In order for this plugin to be able to address the ClamAV-daemon service, the service must be listening in the right place - in this case at This can be checked in the server's terminal.

Using netstat the TCP socket of the ClamAV-daemon service can be examined.

 sudo netstat -anp | grep -E "(clam)" 

If no line starting with tcp is seen or a different host:port combination is seen as, the configuration has to be checked again.

Example configuration

An example configuration with the above default values:


As soon as a virus signature has been detected, the following message is displayed:

Test file

A common method for checking virus scanners is the file.
At any point this test file can be uploaded and after successful configuration the message shown above should be seen.



ClamAV creates logs which can be found under  /var/log/clamav/clamav.log .

For example, after uploading the test file, the following entry can be seen in clamav.log :

 Wed May 25 10:10:21 2022 -> instream( Win.Test.EICAR_HDB-1(44d88612fea8a8f36de82e1278abb02f:68) FOUND 

Xima® Formcycle logs can be found for this at  /formcycle-data/formcycle7/logs .

After uploading the test file, for example, the following entry can be seen in formcycle-errors-log :

[WARN] [25-05-22 10:10:21,192] [ajp-nio-] ( - Scanner <fc.plugin.malware.scanner.clamAV.
