A human virus is made by human cells, they are from your own body and natural. Any normal flu is your own body making its own virus, they are not alive and not little beings, they are just solvents to clean your body of chemicals, they are made when your body's bacteria are not up to the task of cleaning up.
You got a source for this?
You are correct that a virus is not considered to be a living organism but that is mostly because they are unable to reproduce without invading foreign living cells to gain the materials and mechanism required to make new virus parts. They may be made by the body in that sense but the virus has no apparent value to the living organism it infects unless like with a cancer cell the destructive properties of a virus can be somehow targeted to reduce the cancer's cellular proliferation. In such cases the value is not to clean your body of chemicals but to destroy human cells that have negatively adapted and proliferated. Nor can a virus replace or improve on the work of friendly bacteria -which also don't clean the body of anything-.
Are there any viruses that are beneficial to the human race?
Viruses work by invading the host cell and forcing it to make lots of copies of the virus. This normally kills the cell in the process and is therefore a bad thing. But your immune response to a mild virus might protect you from a more serious infection: cowpox infections immunise you against smallpox, for example.
Alternatively, you could be a carrier for a virus that doesn’t hurt you much but is much more serious for a competing species: chimpanzees carry an immunodeficiency virus that can be transmitted to gorillas (for example when fighting), though I don’t know of an example in humans.
Finally, there have been some early trials in mice with viruses that appear to target tumour cells and kill them, including the Sindbis virus, which is transmitted by mosquitoes in Egypt.
Nothing you believe is based on recognized science Daniel. Why does that somehow make you feel safer?
