Schedule ClamAV scanning via Cron

گروه آموزشی مجموعه تدبیر

This is a simple Bash script for those who want to schedule the following tasks via cron:

  • update the ClamAV virus database (freshclam);
  • perform personal system scan (clamscan);
  • send a brief report via e-mail;

without any knowledge about ClamAV configuration files (such as clamd.conf or freshclam.conf) and without running the ClamAV daemon. You just have to configure the e-mail address(es) that will receive the report.

Dependencies:

To succesfilly run clamav-cron the following dependencies needs to be satisfied:

  • the ClamAV engine (look at ClamAV download center);
  • a mail server like Sendmail;

How to use:

  1. Download clamav-cron somewhere like /usr/local/bin/ and give it execute permission:
wget http://clamav-cron.googlecode.com/files/clamav-cron-0.6 -O /usr/local/bin/clamav-cron
chmod 755/usr/local/bin/clamav-cron
  1. Simply open the clamav-cron script with your editor and edit the “User configuration” section following the instructions;
  2. schedule the clamav-cron script via Cron in the preferred way. For example, you can install the clamav-cron in the crontab typing crontab -e from the user shell and entering a line like this:
4523**6/usr/local/bin/clamav-cron /home

Cron will run clamav-cron every Saturday at 23:45 (11:45 pm) to recursevly scan the whole /home tree. At the end of task it will send a notification e-mail to the users specified at point 2. For more crontab option type man 5 crontab.
