The expression "avoid somebody/something like the plague" is used to describe when you don't want to be around a person or thing because they could be very harmful or dangerous. It comes from the idea of a deadly disease, the plague, which people in the past would avoid at all costs. So, if you say "I'm going to avoid that person or thing like the plague" it means that you don't want to be near them because they could cause harm or trouble.
