The only way viruses can replicate is by parasitizing living cells and using the cell's mechanisms to replicate their genetic materials and protein components.

viruses are non cellular , they have no sexual or asexual reproduction they reproduce by replication
Viruses can be classified based on their structure (DNA or RNA, enveloped or non-enveloped) and their method of replication (lytic or lysogenic life cycles).

Viral replication is the process of creating viruses. This can only occur once a virus has infected a cell - because viruses cannot replicate by themselves (they need to use a host cell).
They need a living cell. It is essential for replication.
I believe, exogenous virus exist as: "replication competent viruses that are transmitted horizontally in mice, while endogenous viruses exist as germline sequences that are usually not replication competent by may recombine with exogenous viruses during the course of infection." This would refer to exogenous retroviruses.
Viruses replicate to produce more copies of themselves and spread to new host cells or individuals. This replication process is crucial for the survival and propagation of viruses in their environment.
Viruses evolve primarily when they replicate and undergo mutations during their replication process. This can occur in response to environmental pressures, such as host immune responses or antiviral treatments. Additionally, viruses can exchange genetic material with other viruses through reassortment or recombination, leading to significant evolutionary changes. Overall, the rapid replication rates and high mutation frequencies of viruses facilitate their evolutionary adaptability.
they must find a host cell in the infected body and take it over to force it to replicate
Viruses can not replicate without a living host cell. This is one reason that they are not considered to be alive.
Viruses are replication parasites that can do nothing until they take over a living cell. Bacteria are living cells.
