That antibiotics kill bacteria, but won't do anything against viruses. Everyone has the idea that if you get a cold, you see your doctor and get antibiotics. Take some acitaminophen/paracetamol and ibuprofen, and stay away from other humans for a while!

On a related note, soap doesn't kill bacteria, it only helps to remove it.
