What is a rootkit? Isn that something that virus writers use?
A rootkit is a powerful piece of software that takes over control of a computer at the most fundamental level. In computer terms, it establishes “root” access, which is similar to administrative access, instead of access for just an ordinary user. It can potentially prevent a computer user from detecting its presence or from performing certain tasks on their own PC.Like most computing tools, this is not intrinsically a bad thing, but can be abused. Virus writers use these tools to help take over computers and hide the presence of their work.
