Rootkit scanner is scanning tool to ensure you for about 99.9%* you’re clean of nasty tools. This tool scans for rootkits, backdoors and local exploits by running tests like:

- MD5 hash compare
- Look for default files used by rootkits
- Wrong file permissions for binaries
- Look for suspected strings in LKM and KLD modules
- Look for hidden files
- Optional scan within plaintext and binary files

Rootkit Hunter is released as GPL licensed project and free for everyone to use.

* No, not really 99.9%.. It’s just another security layer
