Answer:

interfere with viral replication

Explanation:

Interferons (IFNs) are proteinous molecules, which are part of the innate immune system of our body. Interferons are produced in response to viral infections and they often specialize in preventing the virus pathogen from replicating or multiplying in the host cell.
