There are no known viruses that can be hosted by a tree. There are however parisites and Fungi that can be harmfull to any plant, shrub, or tree. The only example I know of where a tree might harbor a viruse is if a bark beetle was to by chance have the flu.
False. Example- apple trees are infected by the apple mosaic virus which causes the apple trees to produce less food.

Oncolytic viruses are viruses used in cancer treatment. They kill these viruses through chemical means in multiple stages by attacking infected cells.
PC viruses are usually 'contracted' from the internet - or by inserting an 'infected' disk into the computer's drive.

White blood cells
Prokaryotes can be infected by viruses.
Antibiotics do not work on viruses because viruses are not cells which can take in and out or be infected by specific processes.
Vaccines don't kill viruses or diseases; they prevent disease before you are infected.
More viruses. Cells infected with virus DNA are essentially converted into virus factories. Instead of producing the materials the cell needs to reproduce, it produces dormant viruses, until the cell bursts and the new viruses begin infecting other cells.
viruses occur if a person does not take care of himself/herself and then becomes infected an then spreads it on to another person and so on.
