A scab xxx
A scab is produced by platelets and it stops the bacteria getting through the body which saves work for your white blood cells. The scab gets hard and makes a ''barrier'' to stop germs getting in your body.
A Scar :)
A scab is a dried-up, crusty patch of dead skin on any part of your body on the skin. A virus is completely different from a scab, because a virus is what messes up computers, or carries colds and other diseases (diseases like the flu, the common cold, etc.) that affect human health. Though, the only way in which a scab and virus are related is that if the scab is scratched off, or there is an open spot in the scab, a virus could enter the body through the scab.
A scab
When you get a cut or injury, your body forms a scab as part of the healing process. A scab is a temporary crust that forms over the wound to protect it from bacteria and debris. Underneath the scab, new skin cells are busy repairing the damaged tissue.
The answer to this riddle is "scar." As a wound heals, new tissue forms over the damaged area, creating a scar. By changing one letter in "wound," which is the word mentioned in the question, you get "scar."
