Viruses aren't as "living" as the other three that you mentioned. The only thing viruses have in common with them is that they move. Viruses do not eat, breath, grow, or reproduce. They do reproduce, but not independently.
Instead of taking over the host right away, many viruses go into a dormant stage, which means that they wait for the right time and climate (which could even take over a year, like most symptoms of HIV, for example) to do their job. Also, viruses do not attack until inside the cell wall. From there, the virus sends genetic material into the cell membrane, and the cell immediately goes to work reproducing the virus.
The only reason viruses care to survive is to reproduce, and we don't know why.
The first paragraph should have mainly answered your question, I just wanted to make sure you know the important facts--they help. Please give feedback! Thanks.
Viruses differ from bacteria, fungi, and parasites in that they cannot reproduce independently; they require a host cell to replicate. While bacteria and fungi can divide and reproduce on their own through processes like binary fission or budding, viruses hijack the host's cellular machinery to produce new viral particles. Additionally, parasites are typically multicellular organisms that can reproduce sexually or asexually within or outside a host, whereas viruses are acellular and rely entirely on their host's biological processes for replication.
The four broad types of pathogens are bacteria, viruses, fungi, and parasites. Each type of pathogen can cause various diseases and illnesses in humans and other organisms.
Pathogens. These are typically bacteria, viruses, fungi, or parasites that can cause disease by invading the body's tissues. Common examples include influenza viruses, E. coli bacteria, and malaria parasites.
It depends, pathogens can be multicellular (cestoda, fungi), unicellular (bacteria) or they can have non-cellular build (viruses, prions).
There are really 5 main groups; viruses, bacteria, fungi, protozoa (which includes the malaria parasite) and Helminthes (which includes parasites such as flatworms and roundworms). Moulds are classified as fungi.

Skin diseases can be caused by viruses, fungi, bacteria, or parasites.
Prions, Viruses, Bacteria, Fungi, and Animal Parasites.
Bacteria, viruses, fungi, protozoa (aka protists), parasites.
"germs" -- bacteria, viruses, parasites, fungi, and possibly prions
Bacteria, viruses, fungi, protozoa (aka protists), parasites.
Bacteria fungi is an example of a bacterial disease. Parasitic worms is an example of a parasitic disease. Both can make you sick.

Four different microorganisms are bacteria, viruses, fungi, and protozoa. Bacteria are single-celled prokaryotic organisms, viruses are infectious agents that require a host cell to replicate, fungi are eukaryotic organisms that include yeasts and molds, and protozoa are single-celled eukaryotic organisms that can be parasitic.
Bacterial diseases are diseases caused by bacteria, in contrast to those caused by parasites, viruses, or fungi.
White blood cells defend the body against infection from bacteria, viruses, fungi, and parasites.
