A Rootkit virus is a stealth type of malware that is designed to hide the existence of certain processes or programs on your computer from regular detection methods, so as to allow it or another malicious process privileged access to your computer. Sometimes a rootkit may even fool your antivirus software and avoid being detected. It is at such times, that you may need to take help of special Rootkit Remover or Removal Tools.
