A computer virus can become your worst nightmare if you download it on your computer system without getting any type of antivirus program to help protect your computer. Although many viruses are smaller than a virus that is full of code and has infected your computer, some are so small that they do not make a difference with your system until someone takes steps to help remove them. A virus is a self-replicating program that basically spreads itself throughout your entire computer system without your knowledge, making it harder for you to prevent it from spreading.


How does a virus spread? Viruses are spread through the exchange of infected files among the user’s system files, which are called hosts. The files that a virus affects are named its hosts. A virus that is spread through your email system can spread to your host computer because of the exchange of emails that is taking place between the two systems. In other words, your host cell will have a virus in its email attachment if you open or view the email. Other ways in which viruses spread are through game files, music files, video files, and other types of file-sharing systems.

Unlike bacteria, virus spreads through the genetic codes within living cells. This means that if a virus attaches itself to an already existing microorganism, that microorganism is exposed to the virus and therefore becomes infected. However, there is not always a way to know if a virus has attached itself to a host organism. Sometimes, the virus may only be able to replicate itself because there is no resistance within the host organism; sometimes, the host organism can develop some type of natural immunity to the virus.

What makes viruses so dangerous is that once they have started reproducing, their reproductive abilities are in overdrive. This means that a virus will keep replicating itself unless you stop it. However, viruses are extremely tricky as well as hard to protect from. For instance, if a virus were to attach itself to a computer’s motherboard, there would be nothing to stop it from spreading into all of the computers on the network. Not only that, but viruses are highly contagious. They spread not only from one person to another but also from one computer to another in the network.

If a virus spreads from a host cell to another host cell, this is called a host-cell replicate. A virus spreads from host to host in this manner when the DNA of the host cell is copied into that of an additional host cell. Once this happens, the DNA is placed into a replicated form and spread throughout the network. Although this type of virus spreads quickly, it is usually not fatal to those it attacks. However, the virus itself can cause severe damage to its host.

There are a number of different viruses. Some viruses are destructive in nature, while others are simply harmful to the host by causing damage to the genetic makeup of the organism. Some viruses create particles known as viruses. These particles are made of proteins and belong to the virus’s protein family. Other viruses are silent and do not produce any sound or sight whatsoever. The types of viruses and their effects on the host are covered in further detail in other articles.
