Computer virus is a malicious software program loaded onto a users computer without the users knowledge and performs malicious action.A biological virus is asmall parasite that affects the human body or any living organism.The following are similarities between computer virus and biological virus.
Computer virus can block antivirus software to protect itself .Biological virus can attack or compromise the immune system to protect itself.
Computer virus can change the code in its copies to avoid detection by antivirus software. Biological virus can produce copies with mutations that may become resistant to antibodies and drugs
Computer virus can be programmed to cause harm only after certain event such as launch of the app or file containing it. Biological virus virus repricates inside an organisimfor a while without any symptoms known as the incubation period.
Computer virus replicates itself by copying into other computer programs. Biological virus replicates itself only inside the cells of a living organism usimg their resourses.

A computer virus is a said to be a piece of code which is capable of copying itself and typically has a detrimental infect such as corrupting the system or destroying data and it only deals with electrical devices.
Biological viruses are submicroscopic infections agents that only dwells inside a living cell of an organism such as animalas and plants.
To start with both viruses decreases their host performance, When biological viruses enter their hosts cells they replicate then they eventually kill the cells, wheares a computer virus also cause a computer to perform unnecessary tasks which slow down the entire machine.
Both viruses are relatively far simpler than the host they affect , for instance a computer virus contain as few as six lines of codes as compared to the code base of an operating system which have tens of millions of line codes.
Both viruses relay on their host. It is because of their host that the viruses increase in nunbers and spread to other hosts. Biological viruses replicates in a host then induce their host to caugh or sneeze and release bodily fluids which spreads the virus, whereby a computer virus uses machines to replicate itself and then send copies to other electronic devices using emails, messages or any other connections.
Both hide themselves inside the host, making detection difficult. For example biological viruses oftin hide themselves in the white blood cell while inside the host cell, making it hard to trace the virus, Similar computer viruses may look like a simple file indistinguishable from the millions of the other viruses.
In other ways, a virus is a simple construct which can infiltrate a host, harming the host in the process.
in conclusion a computer virus share many similarities with their biological counterparts and therefore, aptly named.

A biological virus is a microscopic infectious agent. First viruses are note life forms. They are not alive but they posses some.
Computer virus is a type of computer program that when executed,replicates itself by modifying other computer programs and insert its own code.
The following are the similarities between computer virus and biological virus;
Self defense; The biological virus can attack the immune sytem to protect itself. And computer virus can block antivirus software to protect itself.
Invisible phase; The biological virus replicates inside an organism for a while without symptoms. And computer virus can be programed to cause harm only after a certain ever.
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 thousands base pairs making up its genome where as a human has more than three billions.
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 replicates in a host then induce the host to cough,sneeze which spread the virus to other victums.
Both viruses decrease the performance of their hosts. Biological viruses enter the hosts cells,replicate,then eventually kill those cells. Many computers 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 millons of other files around it.
A computer virus, is a type of computer program that, when executed, replicates itself by modifying other computer programs and inserting its own code.
Biological virus, is an infectious agent of small size and simple composition that can multiply only in living cells of animals, plants, or bacteria. the following are the similarities between computer virus and biological virus.
SIMILARITIES:
COMPUTER VIRUS-
1 They severely attacks the computer system.
2 Spread from one computer to another.
3 They increase in numbers through different files.
4 Parasitism: copied by host.
5 Can be prevented by the use of anti-vius
BIOLOGICAL VIRUS-
1 They severely attacks the human body.
2 Spread from one human to another.
3 They multiplies within a very short span.
4 Copied by host cell.
5 Can be prevented by the use of antibiotics.
Therefore both viruses computers and biological, share the same characteristic of some sort of 'intelligence'. In the case of computer viruses, that intelligence is the reflection of the intelligence of the programmer. In the case of biological viruses, it is less obvious where that pre-supposed intelligence comes from.
