                                MALWARE

                      Malware is a type of malicious program designed to damage or carryout other unwanted

                      actions on a computer system. In Spanish, 'mal' is a prefix meaning 'bad,' making the term
                      'badware,' which is a good way to remember it.

                      There are different types of malware programs that can affect the computer.

                      VIRUS

                      Virus stands for Vital Information Resources Under Seize. It is the kind of malware that

                      is created deliberately to damage critical information and data. It interferes with the
                      normal operation of a computer and attaches itself to any type of file. Due to this, when
                      we copy a file which has a virus, our computer gets infected. Before we know about it,
                      our computer starts malfunctioning, and our files and operating systems tend to get

                      damaged.

                                                                                                              PURE
                          In 1986, the first virus 'Brain' was made by two brothers, Basit and Amjad Farooq
                          Alvi.                                                                                FACT

                      Symptoms of Virus

                      If a computer works differently from usual, it might have been infected by a virus. Some of
                      the symptoms of your computer having a virus are:

                         The computer runs slower than usual and takes more time to load programs.

                         The computer freezes frequently and stops responding.
                          Memory of the computer becomes lesser than expected and new files keep appearing
                        with strange names.

                          Warning messages like Your PC is stoned appears or unusual images are automatically
                        displayed on the screen.

                          The  operating  system  faces  trouble  in  starting  up,  or the  computer  may  shut  down
                        unexpectedly.
                         Sometimes music and unusual sounds play automatically.
