If you are extremely worried about root kits you would need to start with a clean system and then whitelist any "positives". If your concerned you would have to use the tedious method of using dpkg to determine what package a file belongs to, one at a time, and then compare it's checksum to the back installed... I would also recommend using only the latest version from the website directly http://chkrootkit.org/... Source: almost 3 years ago
