  Good question!
  
  Some molecules of microbes (bacteria, viruses, fungi) are so different to our own molecules, that if our immune system detects them, they definitely KNOW they are not from our own body and can safely attack the cells which have these as they will be foreign. They are down as pathogen associated molecular patterns (PAMPs). This is the basis of how our INNATE immune system works.
