This question is strangely placed and/or worded.
If you mean biological viruses:
viruses harm people in many different ways, depending on the specimen. Generally, they inject DNA into your cells, "hijacking" them for their own selfish needs. Mainly for reproduction.
If you mean Computer Viruses:
computer viruses work as most other programs do, but with an interesting twist. They exploit your files in a way similar to the explanation above. Quite fascinating.
Viruses are harmful because they invade host cells and replicate, which can damage or destroy the cells. This can lead to inflammation and tissue damage, causing symptoms of illness. Additionally, the immune response to viral infections can sometimes be overly aggressive, leading to further damage to the body.
viruses can corrupt files on your computer.
Antibiotics like penicillin work by killing the bacteria that cause the disease while they are inside the body. They damage the bacterial cells without damaging the body's cells. They don't work on viruses because viruses invade body cells in order to reproduce.
ofcourse dear viruses damage a computer a lot .... coz there are no ways to damage any computer without any viruses ........ viruses came from unauthentic sites ... so u can use antivirus for protect your computer from viruses....you can download free trial version from net ..... thanxxx
Your immune system is responsible for defending the body against viruses and bacteria. Your body is exposed to hundreds of different viruses and bacteria every day but its immune system allows it to kill these threats before they can multiply and cause damage. Most of these threats are killed before they can do any damage at all but some viruses (such as the flu) multiply and attack the body. While you are ill for a few days the body creates a way to kill the threat and you get better from the virus - without an immune system you would not have the necessary cells to overcome an infectious or bacterial illness. If your immune system is damaged (a good example would be HIV/AIDS) the body loses its ability to fight these dangers and as such viruses and bacteria cause damage to the tissues of the body as there is no system working to destroy them.
Some scientists are hoping that viruses can be modified to undo damage by other viruses, but there is no actual working "damage control" virus available as of July of 2013. Many scientists are concerned that even the good virus might have unwanted side effects.
yes. viruses are never completely removed from the body.
In the body
Viruses are harmful because they invade host cells and hijack their machinery to replicate. This can cause damage to the host cell and trigger immune responses that can lead to inflammation and tissue damage. In severe cases, viral infections can spread throughout the body and cause systemic illness.
Viruses make us feel ill by invading our cells and causing damage to our tissues. This triggers an immune response that can lead to symptoms such as fever, muscle aches, and fatigue as our body fights off the infection. Additionally, the toxins produced by viruses can contribute to the symptoms of illness.
INTERFERON is a substance produced by body cells when they are attacked by viruses.
It depends on what you are trying to get out of the body. A person can get many viruses out of the body with antibiotics. Other viruses require more work.
