Hii!

Sorry, but you will have to give entrance exam for admission into the virology or microbiology course in most of the colleges in West Bengal.

Virology is considered as a sub field of microbiology, so let me list down some of the microbiology Colleges in West Bengal for you-

* University of Calcutta, Kolkata

* Maulana Abul Kalam Azad University of technology, Kolkata

* West Bengal State University, Barasat

* Vidhyasagar University, Midnapore

Etc.,

Hope this helps.

Good luck!
