    Protecting Your Computer From a Computer Malware

                      Malware, or malicious software, is a software made to cause harm to your system. A malware gets
                      installed on a computer without approval from the computer's owner.
                      Types of Malwares

                      There are different types of malware, each having unique characteristics. Let’s find out.

                                                                             Worm
                                                       Virus

                                                                 MALWARE            Trojan
                                                                                    Horse

                                                                                Adware
                                                          Spyware

                          Virus: A computer virus is a program that is able to copy itself when it is run. It gets activated
                         each time the program or file to which it is attached is opened or executed. It is the most common
                         type of malware. It can spread itself by infecting other programs or files. It affects the original
                         program, causing it to not work properly.
                          Worm: A worm is similar to virus but it can copy itself and spread rapidly to any device attached.
                         A worm does not need any program to activate it.
                          Trojan Horse: A trojan horse is a malicious program. It represents itself as helpful software
                         program. Once the user clicks on it to agree to run it, it gains access to sensitive data and then
                         modifies, blocks, or deletes the data. It cannot copy itself from one computer to another.

                          Spyware:  A  spyware  steals  important  information  and  data  on  the  device,  such  as  account
                         passwords or bank details. It observes the user's activity without their knowledge.
                          Adware:  An  adware  tracks  user's  browser  and  download  history  and  keeps  popping
                         advertisements on the screen.

                               In 1986, the first virus was written for Windows based PCs by two brothers,
                               Basit and Amjad Farooq Alvi, from Pakistan, who were only 17 and 24 years old,
                               respectively, at the time. They named it “Brain”.

                      The Most Dangerous Malwares Known

                         Wabbit Virus (1974) makes multiple copies of itself until the system slows down and crashes.
                          ILOVEYOU Virus (2000) worked by sending a fake “love letter” that looked like a harmless text
                         file.
