                   Malware


                 A malware is a type of malicious program designed to damage or carryout other unwanted
 82              actions on a computer system. In Spanish, mal is a prefix that means bad, making the term                83

                 badware, which is a good way to remember it.

                 There are different types of malware programs that can affect the computer in the similar
                 way a virus do. Some of them are worm, trojan horse, spyware, ramsomware, rootkit and

                 backdoor.


                   Worms

                 A computer worm is a type of malware that has the capability to replicate itself without any

                 human interaction. It consumes lots of memory space during replication. Once a computer
                 has  been  infected  by  a  worm,  its  processing  speed slows down,  works  unexpectedly,  and

                 halts other tasks. A computer worm can spread itself from one computer to the other by
                 replication process.


                    Trojan Horse


                 The purpose of a trojan horse is to conceal itself inside the software that seems legitimate.
                 When the software is installed on the system, the trojan gets activated and infects the host

                 system.


                   Spyware


                 Spyware is a type of malware program. The primary function of the spyware is to snoop on a

                 user’s activity and sends back the information it gathers to a hacker.
