They can kill you.
Emerging viruses
Likely the human activity that is most closely associated with the emergence of viruses in humans is urbanization. The closeness caused the viruses to promulgate more efficiently than in communities where there not as many people.
Viruses that are harmless to humans can be used to infect bacteria or other pests eg rabbits
Bacteria,fungi,or parasitic worms invade the human body.
Humans are not affected by plant viruses primarily because these viruses have evolved to infect plant cells, which have different cellular structures and biochemical pathways than human cells. Plant viruses typically rely on specific receptors and mechanisms found only in plant species, making it unlikely for them to successfully invade human cells. Additionally, the immune systems of humans are designed to recognize and combat a wide range of pathogens, including viruses, further protecting us from plant viruses.
The same reason it is important for humans. It protects them from some diseases and viruses. Obviously not all though.

the viruses help the immune system adapt and get stronger
Computer viruses are currently unable to spread to humans.
Just about anyone who gets the flu. Most of the influenza viruses that cause disease in humans are Type A influenza viruses (but not all). Type A flu viruses are also what cause pandemics in humans.

There are quite a few different dog viruses that are infectious to human beings. Other dog viruses die before they can infect humans.

Yes, animals get viruses just like humans does it is a pathogenic disease that is transmitted by a molecule
There are no known phone viruses
