                  Data and information stored on a computer are extremely valuable for both organisations and

                  individuals. Protecting these assets is essential, as losing data can be very damaging. To keep
                  computer systems and their data safe, people use various preventive measures. One common
                  threat to data security is a virus attack.
                     WHAT IS A COMPUTER VIRUS?

                  A computer virus is a malicious piece of code or program designed to corrupt data or program files
                  stored on a computer system. It infiltrates the system without the user's knowledge or consent,
                  often going undetected. Initially, viruses may only affect one computer, but if that computer is
                  connected to a network, the virus can spread to other systems, much like a biological virus spreads
                  between people. Once inside a computer, viruses disrupt normal operations, affecting resources
                  like processing power, memory, and installed software. This can lead to a slowdown in performance
                  or, in severe cases, cause irreversible damage to the hard drive. The acronym VIRUS stands for 'Vital
                  Information Resources Under Seize.

                  Harms Caused by Computer Viruses

                  Different viruses can impact your computer in various ways:
                      They can cause your hard disk to crash.
                     They may delete all or some of your data.
                     They can slow down your computer's processing speed.
                     They might reduce or block access to your computer's memory or hard disk.
                     They can prevent you from restarting your computer or cause it to repeatedly restart.

                     They can send emails from your account without your knowledge.
