                  Higher Order Thinking Skills (HOTS)

                  1.   What could cause a computer to exhibit strange behavior such as slow startup and unusual
                      error messages? Could it be due to a virus? If so, explain how a virus could cause these
                      symptoms and identify potential types of viruses that could be responsible.

                  2.   What steps should be taken to protect a computer that is running slower than usual and
                      occasionally displays strange pop-up ads? Could this be a potential malware issue? Explain
                      the necessary actions to safeguard the system.

                  A.  Guess my name.
                      1.  My name resembles a microorganism. My primary goal is not to
                         cause damage but to replicate myself on the host system.                     ................................

                      2.  I specialise in concealing myself. Although I belong to the cyber world,
                         my name has its origins in Greek mythology.                                  ................................

                      3.  I am used to illegally accessing data data of the host system by
                         encrypting it.                                                               ................................

                      4.  I am also known as a file-infecting virus that infects executable files.    ................................

                      5.  I can isolate all infected files and applications so that the
                         infection cannot spread further.                                             ................................
