Free rootkits software for windows

Removing rootkits without compromising system integrity is particularly challenging and needs to be done with care.
Sophos Anti-Rootkit will find and remove any rootkit that is hidden on your computer.
The term rootkit is used to define a Trojan (or technology) used to hide the presence of a malicious object (process, file, registry key, network port) from the computer user or administrator.
Main features:
- Scans running processes, windows registry and local hard drives for rootkits.
- Identifies known rootkits and selects, by default, files for removal which will remove the rootkit component of the malware without compromising OS integrity.
- Allows users to remove unidentified hidden files, but does not allow removal of essential system files when hidden by an identified rootkit.
- Once the user has run a scan, the screen prompts the user through the necessary steps until every rootkit has been removed.
- Users can switch between the GUI and command-line functionality.
- Both context sensitive and command-line help are available.

RootKit Hook Analyzer is a security utility which will check if there are any rootkits installed which hook the kernel RootKit Hook Analyzer is a security utility which will check if there are any rootkits installed on your PC which hook the kernel system services.
Kernel RootKit Hooks are installed modules which intercept the principal system services that all programs and the operating system rely on.
If any of these system services are intercepted and modified it means that there is a possibility that the safety of your system is at risk and that spyware, viruses or malware are active.
Kernel hooks are out of fashion these days and not officially documented and considered deprecated by Microsoft. The pioneering heroes of the old days who discovered how to actually implement them have all adopted the new fashion of advising against using kernel hooks as a programming practice.
Often kernel hooks are unnecessary because there are documented ways which allow a programmer to achieve his goal. However in a lot of system tools such as monitoring and antivirus software, kernel hooks are the only available technique to get the difficult job done and thus an unavoidable necessary evil.
Important is that if your kernel system services are hooked that you can find out which is the responsible software that makes use of these techniques. Inspired by all the discussions going on about the Sony CD protection rootkit, we have developed the RootKit Hook Analyzer.

The ARIES Rootkit Remover was desgined to locate and permanently remove the Sony rootkit from the system and disable the rootkits ability to run once more after reboot.
This standalone tool is a reliable, trustworthy, and safe way of removing the rootkit--unlike Sonys own rootkit remover that has been known to cause blue screens.
This primarily protects consumers and ensures privacy. The tool is developed by Lavasoft in line with our common goals to steer computing environment towards better standards.
