While humans may not like to get "sick", part of natural selection and the life cycle include disease. Pneumonia has been termed "The Old Man's Friend", aiding with the end of life. The same would be true with the animal kingdom.
Over the last century, a number of vaccines have been developed using mutated viruses, or similar viruses to highly dangerous viruses. For example, the cowpox virus provided immunity for smallpox, and was instrumental in the eradication of that deadly disease.
In recent times, viruses have been used as transport mechanisms to introduce genes into cells, and will likely be central in a new field of gene therapy.
A virus can help its host by destroying a bacterium, fungi, or other foreign body that harms the host leaving the host itself unscathed. This creates a symbiotic relationship between the host and the virus. This may sound improbable, but viruses normally can only target one species and then only one type of cell of that particular species, allowing for this.
In fact, the use of viruses to combat bacteria was attempted in a toothpaste a number of years ago, but was unsuccessful mainly because the manufacturers failed to convince enough people that viruses could actually be good for them.
They can be used in genetic modification as a vector to insert gene into the genome of a target cell.
This has happened naturally in a few occasions, hence why much of human DNA is derived from viruses (retroviral DNA).
there is no actual health or economical benefits we have from virus. But they are a great tool on understanding many molecular concepts on research. Attenuated or inactivated viruses serve to make vaccine against a particular disease. Viral enzymes can be useful for large scale production and sale in research sector.
Viruses be used to fight off bacterial infections in humans.
Some viruses target bacteria or fungi, which can be harmful to humans. These viruses are called "bacteriophages" or sometimes just "phages".
Viruses that are harmless to humans can be used to infect bacteria or other pests eg rabbits
Bacteria can be helpful by deleting bad viruses and harmful by killing you

mould is a helpful one and bacteria is a harmful one
No, viruses are nonliving.
There are no real "Helpful Viruses". Viruses are viruses. They make things go wrong with your computer.
Viruses might be helpful because they clean you out all bad germs and bacteria releases.
no virus is helpful, they damage your software
no virus is helpful, they damage your software
no virus is helpful, they damage your software
viruses can be helpful because, some viruses can be used for cures. for example, USA. researcher suggest that adeno-associated viruses type 2 can Promises to be a breakthrough in cancer therapy
they can kill you
yes it does
- some viruses can be used in biological weapons- some viruses are used in the fight against pests
No. Any and all viruses are parasitic. There may not be any helpful viruses, but there are certainly a large quantity of harmless viruses, which doesn't infect humans, but rather specific animals or plants.
