They attach to the membrane at specific receptor sites. Once attached the virus injects its DNA or RNA into the cell. Enveloped viruses are enclosed in a membrane similar to that of the host cell. The virus and the envelope fuse and the virus enters the cell through endocytosis. To make it easier viruses hijack a cell then they inject their genetic material into the cell and try to take over then it uses the cell to make more
