Learn More About Computer Virus
First of all, it is important to know what a virus does when it attacks the human body before we can fully comprehend how a computer virus works. Microorganisms such as viruses, are only able to divide within another living cell. It is typically harmful to the cell or body in which it lives, and is the cause of many illnesses and diseases.
Viruses are toxins and are therefore toxic to the human cells, they divide within the body causing illnesses such as chickenpox and German measles. What do human viruses and computer viruses have in common? The computer virus can be anywhere on your pc, usually hidden within a program, file or document.
Criminals, and other talented idiots with nothing better to do with their time, create these viruses and spread them to other people’s computers. This activity’s sole purpose is to create trouble and damage for every pc user. Other computers, files or documents can be ‘infected’ by the computer virus, similar to a common virus like the flu (which spreads from one person to another). Files and documents; such as word-processing documents, spreadsheets, emails, computer programs etc can have a computer virus spread through them. As well as through removable storage devices such as memory sticks and floppy disks, it can spread itself through the Internet and through local computer networks. As it is concealed and difficult to identify, it can be inadvertently passed on to other computer users.
Akin to a human virus that makes a person feel unwell, the computer virus works in a similar fashion within a computer. What each type of ‘digital virus’ will do to your computer depends on what it has been programmed to do, it can be very harmful, while others are created to simply annoy and will literally make your computer ’sick’. Macro Viruses, Email Viruses and Trojan Horses are examples of terms used to describe different types of computer viruses. It will be easier to protect your computer against viruses, once you have an understanding of the workings of computer viruses.
