A rootkit is a set of utilities which can run hidden on a computer system, often with the intention of providing secret access to (and control over) the computer's operating system. Usually hackers, viruses, worms and other malicious entities use rootkits to hide their presence on infected systems.

Virus scanners operate by searching your harddisk(s) for files which might be infected by a virus. This method is never 100% secure, since only known viruses (or known virus patterns) are detected. If an infection has been detected in a certain file, the virus scanner might be able to clean the file, but very often this is not the case. In that case, you can try another scanner to clean the file, you can try to replace the file or - as a last resort - delete it.
