Debian/Ubuntu Anti-Virus and Root Kit Scan Script
A customer requested this script, once I started working on it I realized how useful this could be. I have this setup on a weekly CRON task. The script is very simple, it updates ClamAV and RKHunter then scans the server with both and mails the results to the specified email address. If you plan on adding this script to your server, you might want to ensure that you have the correct versions of ClamAV and RKHunter.
