    Ransomware

                      Ransom is  the money  demanded  to  release  the hostage  kidnapped  for the  purpose.  Similarly,
                      ransomware  is  malicious  software  used  to  kidnap  the  data  on  the  host  system  by  encrypting  it.
                      The victim of the host system has to pay a huge amount of money to the attacker to get back access
                      to their data.

                           Rootkit
                      Rootkit is a type of malware that gains administrator access to the host system. Once the attacker

                      has access to the system, the rootkit remains hidden but while retaining special privileges. Detection
                      of a rootkit is challenging because it can bypass tracking software due to its elevated access.

                      There are several methods of eradication:
                         Removing the code in the infected file which corresponds to a virus.

                         Removing the infected file.
                         Quarantining the infected file involves moving it to a location where it cannot be executed.

                         Informing the user about the presence of the malware and the action that has been taken.
                         Separating all infected files and applications to prevent further spread of the infection.

                      Some well-known antivirus programs are Norton, AVG, McAfee, Symantec, SmartDog, Kaspersky, etc.
