Answer: rootkit
Explanation:
Hi, A rootkit is a collection of computer software, typically malicious, designed to enable access to a computer or an area of its software that is not otherwise allowed (for example, to an unauthorized user) and often masks its existence or the existence of other software.
A rootkit provides continued privileged access to a computer while hiding its presence. Because of this hiding characteristic it is very difficult to detect.
