 Rootkit is defined as malicious software that can allow an unauthorised user to gain access to a computer. This application or software can allow hackers to gain remote access to the computer and will remain undetected in the computer. When hackers make use of some tips and tricks to steal passwords of a user or when they trick users with a malicious link that downloads this malicious application into the user system, they install a backdoor in the background. This entire process may not be noticed by the user and this can give them full-time access to the computer as long as it is powered on.

         Rootkits are usually designed by hackers to provide them administrator privileges. When there are vulnerabilities in a computer or in the applications installed on the computer, hackers try to exploit them and install these rootkits without the knowledge of users. When there are rootkits installed on a computer, one can observe some kind of strange behaviour on the computer.

If such kind of unwanted behaviour is observed, the best method to remove such rootkits is to format and rebuild the entire system.

The applications installed on the computer have to be downloaded from trusted sites only and they must also be updated regularly.
