The above answers are quite right. The protein capsid of naked viruses is less susceptible to environmental conditions (lipid solvents, pH, temperature...) than enveloped viruses because the envelop is made in part of phospholipids. Once the envelop is lysed, the virus loses its functional receptors and is not still able to infect susceptible cells. ...
Many different viruses can bind to the same receptor and a single virus can bind different cell surface receptors. While viruses use them to their advantage, cell surface receptors are actually designed to serve the cell. After a virus binds to the surface of the host cell, it can start to move across the outer covering or membrane of the host cell. There are many different modes of entry. HIV, a virus with an envelope, fuses with the membrane and is pushed through. Another enveloped virus, the influenza virus, is engulfed by the cell. Some non-enveloped viruses, such as the polio virus, create a porous channel of entry and burrow through the membrane.
