    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.

                     Effects of Virus

                       Files become corrupted or the content of the files gets deleted.
                       A virus can damage or destroy the operating system.
                       A virus can reduce the memory space.
