Answer: A virus is a sub microscopic infectious agent that replicates only inside the living cells of an organism.
Viruses live and replicates inside of the living cells, they cannot live outside of this environment. They have different mechanisms and machinery to survive and replicate. That's why it is difficult to cure diseases caused by them.

A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses can infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea. ... The study of viruses is known as virology, a subspeciality of microbiology.
Overuse and inappropriate prescribing of antibiotics worldwide is leading to the global healthcare issue of antibiotic resistance. However, the issue of antibiotic resistance can be confusing for many patients. You may be told you cannot use an antibiotic for a viral infection because they are ineffective and may lead to “antibiotic resistance”.
Why don’t antibiotics kill viral infections, and how can overuse of an antibiotic lead to “antibiotic resistance”?
Antibiotics cannot kill viruses because viruses have different structures and replicate in a different way than bacteria.
Antibiotics work by targeting the growth machinery in bacteria (not viruses) to kill or inhibit those particular bacteria.
When you think about it structurally, it makes sense that an antibiotic could not work to kill a virus with a completely different set of replicating “machinery”.
