Rootkits


Hackers are dangerous criminals who steal sensitive or commercially valuable information, cause damage and endanger, in a worst-case scenario, national security. Cracker is a kind of Hacker who pokes his nose where it does not belong, cracking all kinds of software, from operating systems to games. These criminals many times insert hidden malware or registry entries and thereby damage the operating system or collect their required confidential information illegally.
A rootkit is malware which consists of a program (or combination of several programs) designed to take fundamental control (in Unix terms "root" access, in Windows terms, "Administrator" or "Admin" access) of a computer system, without authorization by the system's owners and legitimate managers. Access to the hardware (e.g., the reset switch) is rarely required as a rootkit is intended to seize control of the operating system running on the hardware. Typically, rootkits act to obscure their presence on the system through subversion or evasion of standard operating system security mechanisms. Often, they are Trojans as well, thus fooling users into believing they are safe to run on their systems. Techniques used to accomplish this can include concealing running processes from monitoring programs, or hiding files or system data from the operating system.
Rootkits may have originated as regular applications, intended to take control of a failing or unresponsive system, but in recent years have been largely malware to help intruders gain access to systems while avoiding detection. Rootkits exist for a variety of operating systems, such as Microsoft Windows, Linux, Mac OS, and Solaris. Rootkits often modify parts of the operating system or install themselves as drivers or kernel modules, depending on the internal details of an operating system's mechanisms.
Rootkit detection and removal
Sophos Anti-Rootkit, finds and removes any rootkit that is hidden on your computer using advanced rootkit detection technology.
Rootkits can lie hidden on computers and remain undetected by anti-virus software. Although new rootkits can be prevented from infecting the system, if you had any rootkits before you installed your anti-virus, they may never be revealed.
Removing rootkits without compromising system integrity is particularly challenging and needs to be done with care.
Simplified management
Using Sophos Anti-Rootkit is easy. Whether you use its simple graphical user interface or run it from the command line, you can easily detect and remove any rootkits on your computer.
Easy to use
Sophos Anti-Rootkit provides an extra layer of protection, by safely and reliably detecting and removing any rootkit that might already have hidden itself on your system.
