clean of nasty tools. This tool scans for rootkits, backdoors, and local
exploits by running tests like:
* Comparing MD5 hashes
* Looking for default files used by rootkits
* Checking for wrong file permissions for binaries
* Looking for suspected strings in LKM and KLD modules
* Looking for hidden files
* Optionally scanning within plain text and binary files
* Checking software versions
* Testing applications

Used to Check for Symptoms of Installed Root Kits
http://www.chkrootkit.org/
This is a set of tools that detect rootkit (a program that hides the
presence of attackers) symptoms on a system.
Rootkits can hide using kernel modules, but they always leave some small
traces that can be detected with this program.
However, it is always recommended that this program be used from a rescue
system or a system with a similar purpose.
