Can a virus be cured with antibiotics?

Where do viruses live in the body?
The virus inside the human body Depending on the type of virus, it seeks for cells in different parts of the body: liver, respiratory system or blood. Once it has attached itself to the healthy cell, it enters it.
Do viruses cause disease?
Every virus-host relationship is different. In most cases, viruses do not cause any disease, and many are beneficial. For example, in mice a herpes virus prevents infection from the plague bacteria.
Do viruses make you sick?
Viruses make us sick by killing cells or disrupting cell function. Our bodies often respond with fever (heat inactivates many viruses), the secretion of a chemical called interferon (which blocks viruses from reproducing), or by marshaling the immune system’s antibodies and other cells to target the invader.

Why can’t antibiotics treat viruses?
