What is an 'enveloped virus'?

Viruses that infect the cell and then destroy the cell and pop out when the cell bursts, these are not enveloped generally speaking. And so the virus particles come out without a fatty lipid layer around them. But other viruses like HIV bud from the cell membrane when they form. So here's the cell and the virus may bud off the cell membrane. They take with them the fatty lipid substance that surrounds our cells. The lipid called bylayer of the cell. And that becomes part of the virus.
