Computer Viruses vs. Biological Viruses
Although computer viruses and biological viruses are not related in any way, they are very similar in many aspects. Both viruses need a host to replicate for a means of survival. Similarly, both enter their hosts passively. Biological hosts are infected by breathing, ingestion, or direct contact while infected software, email attachments and transfers infect the cyber host. Another notable similarity is the fact that both computer and biological viruses need the proper host as well as software and tissue specificity to reproduce efficiently. Computer viruses spread by inserting copies of itself in executable code and documents. Computer viruses can reduce the rate of computer performance, make files inaccessible, or completely wipes out the computer. In comparison, biological viruses replicate at the cost of the host by inserting itself into their cells which can result in pain, fever, and in the worse case, death.
Computer viruses parallel many facets of microbial infection. Unlike biological viruses, computer viruses can be thought of as a virus, worm, or Trojan infection. Computer viruses are programs that infect a computer and modify itself which permits it to spread throughout the computer’s software and hardware. Worms are programs that spread between computers through networking while a Trojan horse infection can make a computer available to non-authorized uses without knowledge from owner. Resembling biological viruses, computer viruses can be latent such as a herpes virus or HIV. Both have evolved to produce numerous variants and modified copies to ensure survival against their host’s means of evolving to protect against the infection. But what makes them different other than the obvious fact that computers viruses are “virtual” and biological are molecular based.
Unlike a biological virus, a computer virus is a small program written by human to alter the way a computer operates, without the permission or knowledge of the user. As stated previously,

    Viruses – A viruses is a small capsule that holds DNA or RNA, viruses, unlike bacteria are not self-sufficient and need a ‘host’ in order to reproduce, for example: ‘Human Body’. When a virus enters the body, it enters some certain cells and takes over making them the new ‘host cell’ which makes the parts the virus needs to reproduce, the cells are eventually destroyed through this process. The most common virus is the ‘common cold’ which has no cure.…

    A virus is a small infectious agent that replicates only inside the living cells of other organisms. A virus is a small parasite that cannot reproduce by itself. Once it infects a susceptible cell, however, a virus can direct the cell to produce many more viruses. Viruses can infect all types of life forms, such as animals and plants to microorganisms, including bacteria and archaea.…

    Viruses are non-cellular obligate intracellular parasites, requiring a living host cell in order to reproduce. A developed viral particle (virion) lacks the metabolic machinery of cells, containing just a single type of nucleic acid (DNA or RNA) encased in a protein coat or capsid. Viruses can be distinguished by their structure and by the nature of their genetic material (single or double stranded DNA or RNA). Viruses that affect humans are more difficult to study because they require living animals, embryos, or cell cultures in order to replicate. The particular host range of a virus is determined by the virus’s requirements for attaching to the host cell and the availability, within the host, of the cellular factors needed for viral multiplication. In some viruses, the capsid is covered by an envelope, which protects the virus from the host’s nuclease enzymes. Spikes on the envelope provide a binding site for attachment to the host. Influenza virus is an enveloped virus with many glycoprotein spikes. Viruses are larger than prions and many times smaller than bacteria. They range in size from 30 to 300 nm.…

    A computer virus is programmed to raid and attack existing computer programs. The virus is sent by an e-mail or activated through a download. The virus program then infects the whole computer system. The virus attaches itself to other programs in the computer and copies itself. Some computer viruses are terrible; they erase files or lock up systems. Viruses must not go untreated.…

    Virus is a toxin or poison. It is a microscopic organism consisting of genetic material. They cannot reproduce without a host cell. When it gets this host cell, it takes over its functions. The cells then continue to reproduce, and reproduces more viral protein. Several human diseases are caused by viruses which include:- smallpox, measles, the common cold, chickenpox, hepatitis, HIV, cold sores, shingles to name but a few. Viruses can spread from person to person, and by exchange of salvia, coughing, sneezing.…

    Viruses are a small infectious agent that can only multiply inside the cells of living organisms although unlike bacteria, fungi and parasites viruses are not living organisms. Viruses can infect any living organism such as humans, plants and animals.

    A virus is a small infectious agent that can replicate only inside the living cells of organisms. Most viruses are too small to be seen directly with a light microscope. Viruses infect all types of organisms, from animals and plants to bacteria and archaea. All viruses have genes made from either DNA or RNA, long molecules that carry genetic information; all have a protein coat that protects these genes; and some have an envelope of fat that surrounds them when they are outside a cell…

    A computer virus attaches itself to a program or file enabling it to spread from one computer to another, leaving infections as it travels. Like a human virus, a computer virus can range in severity: some may cause only mildly annoying effects while others can damage your hardware, software or files. Almost all viruses are attached to an executable file, which means the virus may exist on your computer but it actually cannot infect your computer unless you run or open the malicious program. It is important to note that a virus cannot be spread without a human action, (such as running an infected program) to keep it going.…

    Viruses do not belong to the above 5 kingdoms of life. They are much smaller and much less complex than cells. They are macromolecular units composed of DNA or RNA surrounded by an outer protein shell. They have no membrane-bound organelles, no ribosomes (organelle site of protein synthesis), no cytoplasm (living contents of a cell), and no source of energy production of their own. They do not exhibit autopoiesis--i.e. they do not have the self-maintenance metabolic reactions of living systems. Viruses lack cellular respiration, ATP-production, gas exchange, etc. However, they do reproduce, but at the expense of the host cell. Like obligate parasites, they are only capable of reproduction within living cells. In a sense, viruses hijack the host cell and force it to produce more viruses through DNA replication and protein synthesis. Outside of their host cells, viruses can survive as minute macromolecular particles. Viruses may attack animals and plants. Infectious human viruses can be dispersed though the air (airborne viruses) or body fluids (HIV virus). Epidemic viruses (such as HIV) that are passed from person to person via sexual conjugation are remarkably similar to computer viruses. Unfortunately in humans there is no resident antivirus program to alert you of a potential infection, or to quickly scan your body and delete the invader once it has entered your system. Humans must rely on their amazing antibody and cell-mediated immune response, one of the most complex and remarkable achievements in the…
