Some viruses burst cells during the release stage of viral multiplication, this is referred to as

The process you are referring to, where some viruses burst the host cells to release new viral particles, is called "lysis."

In the viral replication cycle, after the virus has replicated its genetic material and produced new virions (viral particles), it can either cause the host cell to undergo lysis, which leads to the release of these new virions into the surrounding environment. This lytic phase is a crucial part of the viral life cycle for viruses that do not primarily use other methods of releasing their progeny, such as budding.

Lysis typically results in the death of the host cell, which releases a large number of viral particles that can go on to infect other cells. This mechanism is particularly characteristic of lytic viruses, in contrast to temperate viruses, which may integrate their genetic material into the host genome and enter a lysogenic cycle that does not immediately destroy the host cell.
