ESET Anti-Stealth technology (rootkit detection)
A rootkit is a type of malicious program designed to hide and protect malware running on an infected system. Rootkits may be used to hide malicious files, folders, processes or registry keys from detection and/or removal by both malware removal tools and/or manual cleaning. Rootkits can also change the behavior of the infected operating system and introduce additional malware into the system.
Because a rootkit can embed itself deep in the operating system, removal can be difficult without the aid of a tool capable of detecting and removing rootkits.
Anti-Stealth technology is integrated into ESET security products to provide effective rootkit detection before malicious programs gain access to system resources. ESET security products are also capable of detecting and removing rootkits already active on an infected system.
