+chkrootkit (Check Rootkit) is a common unix-based program intended to help 
+system administrators check their system for known rootkits. It is a shell 
+script using common UNIX/Linux tools like the strings and grep commands to 
+search core system programs for signatures and for comparing a traversal of the 
+/proc filesystem with the output of the ps (process status) command to look for 
+discrepancies.
+
+It can be used from a "rescue disc" (typically a LiveCD) or it can optionally 
+use an alternative directory from which to run all of its own commands. These 
+techniques allow chkrootkit to trust the commands upon which it depends a bit 
+more.
+
+There are inherent limitations to the reliability of any program that attempts 
+to detect compromises (such as rootkits and computer viruses). Newer rootkits 
+may specifically attempt to detect and compromise copies of the chkrootkit 
+programs or take other measures to evade detection by them.
