Cytokines that provide non-specific immunity against viruses are: Interleukin, Colony stimulating, Tumour necrosis, Interferon

Interferon is a group of proteins that increases the resistance of cells to viral infection. Interferon also acts as cytokines and are involved in the generation of the immune responses. Three types of interferons have so far been discovered, alpha, beta, and gamma, all of which have immune-modulating effects. Interferons are used in the treatment of cancer and autoimmune diseases. Thus, the correct answer is Interferon.
