What is a rootkit?
Breaking the term rootkit into the two component words, root and kit, is a useful way to define it. Root is a Unix/Linux term that's the equivalent of Administrator in Windows. The word kit denotes programs that allow someone to obtain root/admin-level access to the computer by executing the programs in the kit — all of which is done without end-user consent or knowledge.
