What is the difference between biological viruses and computer viruses?

Biological Virus can kill you

Computer Virus can just kill your computer, not you.

Neither is living.
*computer virus it is software which corrupt the system *biological virus which cause decease in human body

How can you remove Sality virus from your PC?

To remove the Sality virus from your PC, you can use reputable antivirus software to scan and remove the infected files. Make sure to keep your antivirus definitions updated to effectively detect the virus. Additionally, you can use malware removal tools such as Malwarebytes to help eliminate any traces of the virus on your system.

Why is it impossible for you to remove a virus from your DNA?

It's typically impossible to remove a virus from your DNA because viruses integrate into the host cell's DNA, becoming a permanent part of the genome. Removing a virus would require altering the DNA sequence of every affected cell, which is not currently feasible with existing technology.

What is the definition of Corona virus?

Coronaviruses are a group of related viruses that cause diseases in mammals and birds. In humans, they can cause respiratory infections ranging from the common cold to more severe diseases like SARS and COVID-19.

Does the male carry the trichomoniais virus?

Trichomoniasis is caused by the parasite Trichomonas vaginalis, not a virus. Both males and females can get infected with trichomoniasis, however, males are often asymptomatic carriers of the parasite. It is important for both partners to get tested and treated to prevent transmission.

What is the gender of virus?

Viruses do not have a gender. They are microscopic infectious agents that replicate inside living cells.

How virus gets produced?

1.You access the infected website.

2. You download software from a bad website.

3. You get an email that has a itachment that contains a virus.

4.You copy files to your computer from the other Computer that has virus.

How does worm replicate itself?

Worms replicate themselves by creating copies of their code in files or computer systems. They use various methods to spread, such as exploiting vulnerabilities in software or tricking users into running infected files. Once activated, the worm can self-replicate and spread to other computers on a network.

Are type 1 Interferon's virus specific?

Type 1 interferons are nonspecific--they nonspecifically inhibit viral infection inside the host cells. Basically what happens is that once a cell gets infected by a virus, they induce the production of these interferons by the cell, they are then secreted into the extracellular fluid to attach onto plasma membrane receptors of other cells including itself, having an autocrine/paracrine function (IT DOES NOT MATTER IF THE CELL IS ALREADY INFECTED OR NOT)--in result of these interferons binding on the cells (including itself), it initiates the production of antiviral proteins by the cell, which prevent further replication of a virus.

In a nutshell: Viruses induce Type 1 Interferon production which inhibits viral replication in the host cell

What is a viruis?

A virus is a tiny infectious agent that can replicate only inside the living cells of organisms. It typically consists of genetic material surrounded by a protein coat and is capable of causing a variety of diseases in animals, plants, and even bacteria.

How do vaccines work to limit the spread of computer and biological viruses?

they inject a milder form of the disease , so your body won't be fully affected but will remember how to kill the real disease and its weakness

Note, though, that computer viruses are not prevented using vaccines.

How martinus beijerinck discover the first virus?

Tobacco mosaic virus (TMV) is an RNA virus that infects plants, especially tobacco and other members of the family Solanaceae. The infection causes characteristic patterns (mottling and discoloration) on the leaves (hence the name). TMV was the first virus to be discovered. Although it was known from the late 19th century that an infectious disease was damaging tobacco crops, it was not until 1930 that the infectious agent was determined to be a virus.

Please improve this answer if you know exactly how he discovered this virus.

What are the basic components of a virus?

A virus typically consists of genetic material (DNA or RNA) enclosed in a protein coat called a capsid. Some viruses also have an outer lipid envelope derived from the host cell membrane. Additionally, viruses may have specialized structures like spikes or tails that help them infect host cells.

What are the possible effects of metachromatic leukodystrophy?

Metachromatic leukodystrophy is a rare genetic disorder that affects the central nervous system, leading to the breakdown of myelin. Symptoms may include muscle weakness, cognitive decline, and vision and hearing loss. Without treatment, it can result in severe disability and premature death.

Does viruses releases harmful toxins?

Viruses themselves do not release toxins. Instead, they replicate and spread by hijacking the host cell's machinery. However, some viruses can cause infected cells to release toxins as part of the immune response, leading to symptoms of illness.

What is the modern version of virus called?

The modern version of a virus is called malware, which is a general term that encompasses different types of malicious software such as viruses, worms, trojans, ransomware, and spyware. Malware is designed to disrupt, damage, or gain unauthorized access to a computer system or network.

What are viruses not made of?

Viruses are not made of cells. They are acellular entities that require a host cell to replicate and are composed of genetic material (DNA or RNA) surrounded by a protein coat called a capsid.

What is true about viruses?

Viruses are microscopic infectious agents that can only replicate inside living cells. They can infect all types of life forms, from animals and plants to bacteria. Viruses are responsible for a wide range of diseases, from the common cold to more severe illnesses like COVID-19.

What can viruses attach themselves to?

Viruses can attach themselves to host cells, bacteria, fungi, and other viruses for the purpose of infecting and replicating within these organisms. They require a specific receptor on the surface of the target cell to bind and gain entry for their replication process.

Are humans a virus on Earth?

Humans are not a virus on Earth. While humans have had a significant impact on the planet's ecosystems, including pollution and habitat destruction, we are a species capable of positive contributions and stewardship of the environment. It is important for us to find a balance that ensures the well-being of both humanity and the Earth.

What must viruses rely on for replication?

they must find a host cell in the infected body and take it over to force it to replicate

How does a virus take over a body?

A virus takes over a body by entering host cells, replicating its genetic material, and using the cell's machinery to produce more virus particles. This process can disrupt normal cellular functions, weaken the immune system, and lead to symptoms of illness.

What was the very first virus written in 1981 called?

The first computer virus, written in 1981, was called the Elk Cloner. It infected Apple II computers through infected floppy disks and displayed a short poem to the user.

Additional steps that occur when a hidden virus multiplies?

When a hidden virus multiplies, it replicates within the cells of the host organism, using its cellular machinery to make new copies of the virus. The virus then spreads to other cells in the body, leading to further infection. As the virus multiplies, it can overwhelm the host's immune system, resulting in the escalation of symptoms and potentially causing damage to tissues and organs.

How are viruses detected?

Anti Virus software scans your computer for abnormal opertations and foreign code being executed. It then traces where it is coming from. It then uses it's online "Virus Definitions" database (Details about viruses) to find out more about the virus, therefore, giving you the option to remove it.

They can also analyze the code to see if it functions similarly to any known viruses.
