Viruses use their host's metabolic enzymes and some viruses mutate very quickly so they can easily become resistant to drugs.
Viruses are almost biologically inert until they infect a cell.
Antibiotics are primarily produced by fungi and certain bacteria. Fungi, such as Penicillium, are well-known for producing the antibiotic penicillin, while bacteria like Streptomyces are responsible for producing various other antibiotics. Bacteriophages, which are viruses that infect bacteria, do not produce antibiotics; instead, they can be used therapeutically to target and kill bacteria.
Plant viruses have a difficult time entering the cells they infect partly because plant cells are surrounded by tough cell walls that viruses alone cannot break through; however, once inside a plant they can multiply and spread rapidly.
Viruses do not have a habitat in the traditional sense, as they are not considered living organisms. They require a host cell to replicate and survive. Once inside a host, viruses can exist in various parts of the body, depending on the type of virus and its specific target cells.
To find defenses against a eukaryotic microorganism is difficult because we are eukaryotic organisms and any attack on the cell of the microorganism can be an attack against our own cells. This requires a subtle approach. Viruses have no metabolism, are not really living and do not reproduce without a host. So, they leave little open to attack in their simplicity.
Viruses can attach themselves to host cells, bacteria, fungi, and other viruses for the purpose of infecting and replicating within these organisms. They require a specific receptor on the surface of the target cell to bind and gain entry for their replication process.
Viruses are difficult to cure because they invade host cells to replicate, making it challenging to target them without harming the host cells. Additionally, viruses can mutate quickly, leading to the development of resistance against treatments. This complexity makes it challenging to develop a universal cure for all viruses.
A paradoxical effect is one that is the opposite of that which was therapeutically intended.
Viruses can be challenging to eliminate because they can mutate rapidly, making it difficult for the immune system to target them effectively. Additionally, viruses can evade detection by hiding inside cells or evolving mechanisms to avoid destruction. Lastly, some viruses have the ability to establish latent infections, where they remain in the body in a dormant state and can reactivate later.

lichens, corals, viruses, corals, viruses and carnivourous plants are difficult to classify :)
Because you are an idiot
The immune system must attack the bodys own cells
Viruses are so difficult to combat because they are very good at assuming control of cells and multiplying themselves to spread and produce toxins.
Bacteria are generally easier to cure compared to viruses because antibiotics can effectively target bacterial infections. Viruses, on the other hand, are harder to target with medication because they rely on host cells to replicate. Antiviral medications are available but may have limited effectiveness.
It is listed therapeutically for seizure disorder.
Some viruses can be helpful by being used in gene therapy to treat genetic disorders. They can also be engineered to target and kill cancer cells in a process known as oncolytic virotherapy. Additionally, viruses can be used in biotechnology to deliver genetic material into cells for research or therapeutic purposes.
Some viruses target harmful organisms. For example, bacteriophage viruses kill bacteria. Other viruses might kill mosquitoes or weevils or other harmful insects without hurting any other species.
