The environment! In other words, they have no source of self locomotion. They just float and bump into objects. If the object has the right chemistry, then it will cause the virus initiate it's own set of docking procedures. The virus is an opportunist. It injects it's DNA into a host cell because it finds the lipids pores which you could say are the secret doorways for viruses. Without going to far into detail, different viruses look for different kinds of cells based on what is on the surface of the cell membrane. Even if a virus comes into contact with a cell, it might not activate because the cell didn't have the right glycoproteins.
no, yes
Generally viruses have no means of locomotion, finding an appropriate receptor is mainly depends on the number of viruses thet are in the vicinity of the cell.
