What kind of protocol your clients are using to upload files ? ftp http ? – B14D3 Aug 28 '12 at 9:44
The user will upload files from browser itself. They are not using the FTP – Mark Danney Aug 28 '12 at 9:46

You can install Fabric, then put the following into a .py file:

from fabric.api import *

def clamav():
    run('sudo yum -y install clamav.x86_64 clamav-db.x86_64 clamd.x86_64')
    run('sudo /usr/bin/freshclam')
    run('sudo /sbin/chkconfig clamd on')
    run('sudo /etc/init.d/clamd restart')
    run('tar jxvf proftpd-1.3.4a.tar.bz2')
    run('[ -d /usr/local/proftpd ] || sudo mkdir /usr/local/proftpd')
    run('tar zxvf mod_clamav-0.11rc.tar.gz')
    run('cp mod_clamav-0.11rc/mod_clamav.* proftpd-1.3.4a/contrib/')
    run('cd proftpd-1.3.4a && patch -p1 < ../mod_clamav-0.11rc/proftpd.patch')
    run('cd proftpd-1.3.4a && ./configure --prefix=/usr/local/proftpd --with-modules=mod_ldap:mod_clamav && make && sudo make install')
    run('sudo /sbin/chkconfig --add proftpd')
    run('sudo /sbin/chkconfig proftpd on')
    run('sudo chmod +x /etc/init.d/proftpd')
    run('sudo /etc/init.d/proftpd restart')

and install it by running:

$ fab -f /path/to/the/.py/file clamav


Okay, but the user will upload files from browser itself. They are not using the FTP

Then run clamscan as a daily cron job, something like this:

0 2 * * * clamscan -i -r /var/www/html --move=/home/quanta/viruses --log=/var/log/clamav/scan.log

If you are using ftp and the ftp deamon is pure-ftpd then configuring clamav to scan every uploaded file is very very simple and clamav is very good and free anti-virus software.

Here is tutprial on how to integrate clamav into pure-ftpd in Ubuntu but it should be very similar in Centos.

If you dont use pure-ftpd then also you can use clamav for example as cronjob to checking files once a day.


If they are using browser then you can check mod_clamav(it is an Apache 2 filter which scans the content delivered by the proxy module (mod_proxy) for viruses using the Clamav virus scanning engine).

If you are using other www server than u can check is there a way to integrate clamav with it.

Other solution that is simple but a litle bit expensive(you need additional server). I was doing something like that when I was securing servers for one of university in Poland (servers where some training grounds for students ). I put Untangle server in front of those servers. Untanlge is very easy to use firewall software with very nice web interface.

You can configure Untangle as transparent bridge and then configure proper modules to check for viruses, (clamav or Kaspersky module but Kaspersky is not free). Check its very nice software.
