Because antibiotics are designed to fight bacterial infections, whereas antivirals are used to combat viral infections.
Antibiotics won't treat a virus.
Since the flu is a severe upper respiratory infection caused by a virus, antibiotics cannot affect them as viruses are not living and antibiotics only affect living microbes.
antibiotics are only affective against bacteria, and a virus is different then bacteria

The best treatment for a virus is rest and symptom management. Antibiotics will not affect viruses. Vaccines against several viruses have been developed which bolster the immune system, and there are antiviral treatments for severe cases such as HIV.
Antibiotics work against bacterial infections only. They either prevent the bacteria from multiplying or they affect the cell contents of the bacteria and stop the bacteria from constructing their cell wall. However, antibiotics won't work against cold because common cold is caused by a virus. Since virus contains only RNA and is non-living outside host cell, i.e.,there is no cell wall in viruses. so, antibiotics do not work against them. Therefore, it is not advisable to have antibiotics to fight off a cold.
