I know people have mentioned rkhunter, but if you have clamav installed and updated, it is supposed to check for 72 linux viruses/rootkits. I couldn't hurt to run that in a script each night. I do that on some directories. man pages are pretty easy to understand for clamscan and freshclam (to update the files).
