A bilogical virus is a small parasite that cannot reproduce by itself. Once it infects a susceptible cell, however, a virus can direct the cell machinery to produce more viruses. Most viruses have either( RNA or DNA )as their genetic material. The nucleic acid may be single- or double-stranded. While computer virus is a type of malicious code or program written to alter the way a computer operates and is designed to spread from one computer to another. A virus operates by inserting or attaching itself to a legitimate program or document that supports macros in order to execute its code.the compter virus has it type which are Boot Sector Virus , Direct Action Virus , Multipartite Virus , Polymorphic Virus , Resident Virus and File InfectorVirus.
The following are the diferent with the similality of computer virus and bilogical virus .both has the diferent vith image difinition also with the structer.but i will explain with the similality fact.
A)Striking similarities
Both biological viruses (living organisms made up of DNA or RNA inside a protein coating) and their cyberspace counterparts (computer programs written by mean-minded computer boffins) parasitise on their host and can only replicate when inside that host.
Biological viruses enter their host through an opening after passively being breathed in, swallowed or via direct contact. Virtual viruses also enter their 'host' passively when you insert an infected disk or open an infected e-mail attachment. Similarly to a biological virus which has to have the correct host and tissue specificity to gain a foothold - a horse virus wouldn't make a human being sick - a computer virus has to be compatible with the system to gain a foothold.the damage these viruses do, is also similar. Biological viruses replicate at the cost of the host - damage can include pain, suffering and even death. Computer viruses slow down the computer - files can become inaccessible and even lost, and sometimes the complete hard disk gets damaged.
B)Worms and viruses
The term 'computer virus' can actually mean one of three things: a virus (a program that implants a version of itself in any program it can modify and then spreads to files within a computer, or with user interaction like sharing infected disks, between computers), a worm (a harmful program that spreads copies between computers in a network, such as the Internet, without user interaction) or a Trojan horse (a program that makes a computer available to non-authorised users).A virus, worm or Trojan horse can (like HIV) be latent, only to become active after a certain period. This is called a 'logic bomb'. These three classes of computer malware can also have hundreds of variants or several slightly modified versions, which parallel microbial diversity.
C) Spreading across boundaries
Some interesting parallels when it comes to the dissemination or spread of viruses. "Because worms spread without any user interaction, they are like socially transmitted diseases such as influenza, that have the potential to infect everyone susceptible. In contrast, computer viruses are like sexually transmitted diseases. Their spread (through sharing infected diskettes) is like that of STDs, whose spread is related to specific behavioural practices. 'Logic bombs' are like HIV, because they are only activated at a later date," she explains.As with biological viruses, simple hygiene measures can protect you against computer viruses. "Just as people would wash hands frequently, avoid exposure to people with colds, or use condoms to protect against infectious diseases, computer users should mistrust (and thus not open) files received through unexpected channels or with unknown extensions or subject lines, request confirmation from the sender before opening attachments, and regularly back up hard disks to reduce the risk of losing data.
Auto-immune diseases
When your body's immune system runs out of control and starts damaging itself, this is known as an auto-immune disease. Similarly, computers can also fall prey to such diseases. "Recently, a 'warning' turned out to be a not-so-harmless hoax. The hoax warning stated that certain files were infected by a computer virus. Heeding the warning, unsuspecting computer users removed the affected utility files from their computers' operating system. Fortunately, this time it only turned out to be a mild nuisance, because the computers weren't permanently damaged. But a more malignant hoax could be as devastating to computers as some auto-immune diseases are to humans. Biological viruses also 'steal' virulence genes from other viruses and become more malignant. This also happens in the case of computer 'malware'. "Just a week after the September attack against the United States, a highly dangerous worm called Nimda was released. This combined the most powerful strategies of two other worm programs, and spread more rapidly than any other previous worm. Clicking on the subject line of an infected e-mail (to delete it, for instance) itself activated the worm. But because this worm was so fast moving, so potentially dangerous, people saw it right away and responded, so slowing its spread,This is similar to the biological world, where with outbreaks of haemorrhagic fevers such as Ebola, the immense threat of high contagion and lethality prompts effective measures to rapidly recognise outbreaks and prevent pandemics.
So the above are rhe similalities of computer virus and bilogical virus ,those similality explained by fact with Dr Wassenaar helped us to show the simlalities of both virus types .

Viruses are simple constructs which can infiltrate a host then use its own resources to replicate, harming the host in the process.
A computer virus, much like a flu virus, is designed to spread from host to host and has the ability to replicate itself. Similarly, in the same way that flu viruses cannot reproduce without a host cell, computer viruses cannot reproduce and spread without programming such as a file or document.
There are following are the similarities between computer virus and biological viruses
Both biological viruses and computer viruses are relatively far simpler than the host it infects. The rhinovirus which is the typical culprit for the common cold, has a few thousand base pairs making up it's genome where as a human has more than 3 billion. That is like comparing the length of a dime to that of Earth's equator. Similarly, computer viruses may contain as few as 6 lines of code as compared to the code base of an operating system which may have tens of millions of lines of code.
Both types of viruses are nothing without their host. Their hosts are their means to both increase their numbers and spreading to other hosts. Biological viruses replicate in a host then induce the host to cough, sneeze, or release bodily fluids which spread the virus to other victims. Computer viruses use a machine's resources to replicate itself and then send copies to other computer using emails, messengers, or other connections.
Both viruses decrease the performance of their hosts. Biological viruses enter the hosts cells, replicate, then eventually kill those cells. Many computer viruses are designed to cause a computer to perform unnecessary tasks which slows down the entire machine.
Both hide inside of the host, making detection difficult. Biological viruses are well hidden from our white blood cells while inside of a host cell. Similarly, computer viruses may look like a simple file, indistinguishable from the millions of other files around it.
In short, computer viruses share many similarities with their biological counterparts, and are therefore, aptly named.
ignificant characteristic that differentiates them from inert matter as well.

Biological virus is an infections agent of small size and simple composition that can multiply in a living cells of animals and plants.
The following are similarities between a Computer virus and Biological virus.
Parasitism; The biological virus replicates only inside the cells of a living organisms. And in Computer virus replicates by copying itself into other computer programs.
Mutation;The biological virus can produce copies with mutations that they can become resistant to antibodies and drugs. And computer virus can change the code in its copies to avoid detection by antivirus.

A biological virus is a microscopic infectious agent. First viruses are not life forms. They are not ‘alive’ but they possess some significant characteristic that differentiates them from inert matter as well.
They are referred to also as pathogens meaning that they are defined as a disease. That disease is their “raison d’être”, their goal, and their mission.
Viruses can potentially infect any life form, including bacteria (which are also microscopic).
Their nature is mysterious and it’s unclear where and how they have been created during the evolutionary processes.
Viruses share several common characteristics with life but miss many important and fundamental points. For example viruses do not possess cell structures. They are therefore at the ‘edge of life’.
Viruses are often named as replicators, because they are able to duplicate themselves, like a ‘self-photocopy’. Their functioning is therefore different from cells and bacteria which are using Phagocytosis, e.g. absorbing a nearby cell or bacteria.
To that respect viruses try to duplicate while cells or bacteria try to merge.
The replication mechanism in viruses is fundamentally stranger to life. Viruses ‘hack’ cells to force them to duplicate the virus genetic code. They predate the cell mechanism and use it for their own purpose: self-replication.
Viruses are made of genetic material, proteins, and lipids and they cannot spread without vectors, which vectors vary greatly: animals, water, air, blood, etc.
Once again, a virus is not a living organism while a bacteria is a living organism. Therefore the behavior of viruses is to be understood at a different biological scale than life itself.
They appear to rely on informal mechanisms and especially replication which is the main way they seem to achieve their goal of survival: replicating and infecting more and more hosts with copies of themselves.
Viruses are destroyed by the immune system when they infect animals (and especially us… the Humans).
If the immune system cannot destroy them, this usually results in the death of the animal host because the replication mechanism of the virus can infect more and more cells of the animal and prevent vital functions from operating. Not all viruses destroy their hosts, some hosts can coexist with viruses, allowing them to be present in their bodies.
