rkhunter (Rootkit Hunter) is a Unix-based tool that scans for rootkits, backdoors and possible local exploits. [1] It does this by comparing SHA-1 hashes of important files with known good ones in online databases, searching for default directories (of rootkits), wrong permissions, hidden files, suspicious strings in kernel modules, and special tests for Linux and FreeBSD. rkhunter is notable ...
Chkrootkit (Check Rootkit) is a widely used Unix-based utility designed to aid system administrators in examining their systems for rootkits. Operating as a shell script , it leverages common Unix / Linux tools such as the strings and grep command.

SUPERAntiSpyware's virus definitions are updated several times a week [2] and generally receive a build update once a month. [3] The company claims that it is specifically designed to be compatible with other security applications, and can, therefore, be used even when other applications are incompatible with other anti-spyware products.
Hooksafe is a hypervisor-based lightweight system that protects an operating system's kernel hooks from rootkit attacks. [1]It prevents thousands of kernel hooks in the guest operating system from being hijacked.
Rootkits are notoriously used by the black hat hacking community. A rootkit allows an attacker to subvert a compromised system. This subversion can take place at the application level, as is the case for the early rootkits that replaced a set of common administrative tools, but can be more dangerous when it occurs at the kernel level.
