                      Do not open emails or attachments from unknown source.

                      MALWARE

                  Malware is a broad term for various types of malicious software designed to damage, disrupt,
                  or gain unauthorised access to a computer system. It can also perform other unwanted actions,
                  such as stealing data or spying on users. In Spanish, 'mal' is a prefix that means 'bad,' making the
                  term 'badware,' which is a good way to remember it.

                  There are different types of malware programs that can affect your computer similarly to viruses.
                  Some of these include worms, trojan horse, spywares, ransomware, rootkits and backdoors.
                  Let us discuss these in detail.
