A rootkit remover is a type of virus/malware remover that scans, identifies and removes rootkit viruses and programs from a computer. Rootkits are a type of malware that tends to override computer/operating administrative controls and procedures.
A rootkit remover is also known as a rootkit revealer, rootkit scanner or rootkit detector.
A rootkit remover works by scanning all programs and utilities that have any level of administrative access and control on a system. They generally scan all levels of rootkits including virtualizes, kernels, libraries and kernel-level rootkits. They review the file system structure and compare it with the best-known structure to identify any abnormalities caused by a rootkit.
Rootkit removers can be part of an anti-virus software or a stand-alone application. They work by scanning hidden threads, services, files registry keys, driver-based rootkits and more.
