Virus cannot replicate it self. It should enter into a host
a virus is able to replicate itself bu taking over the metabolic activities of the cell it infects essentially saying stop what you are suppose to do and make copies of me. so the virus actually doesn't replicate itself but rather the cell in which it infects does it for it. this occurs during the lytic phase of the virus. sometimes the virus "hides" by incorporating itself within the dna of the cell it infects(causing certain cancers) until it is releases itself and says make me. this dormant phase is called lysogenic.
A worm can replicate itself and does not need a host for distribution
A computer program that is designed to replicate itself by copying itself into the other programs stored in a computer.

Viruses attach themselves to and then replicate inside of a cell in order to replicate itself. DNA viruses replicate in a cell's nucleus while RNA viruses generally replicate in the cell's cytoplasm.
Yes. Like all viruses, it goes inside a host cell and replicates itself.
Yes. HIV attaches to the cells, then uses them to replicate copies of the virus.
