Am I right? I feel like I am missing an important point....Can someone please give me a better and easy to understand explanation on this? Thanks in advance.

You are correct in that viruses are smaller than bacteria, but that is not really why they are more difficult to treat.
Viruses are much, much less complex than bacteria. They don't have nearly as many genes compared to bacteria. This means that bacteria produce many more gene products and, consequently, have many more targets for antibiotics to attack. Viruses often produce only a handful of genes, so it is more difficult to find a drug that will kill a viral infection.

The attack of a virus actually does inter-cellular damage - by invading a host cell, and replicating itself using the host cell DNA. In essence changing itself slightly. And eventually destroying the host cell.
Bacteria are simple single cell organisms, where as viruses are even les complex - like a protein chain with a DNA belt or something.
The way a virus basically reproduces, causes it to evolve quite rapidly, which is why flu shots are given annually with the most common antibody strains. Unfortunately, its just hoping that the virus hasn't mutated enough (exchanged too much DNA) that the shot will do nothing to protect the infected host.

Medical science has discovered the way to kill bacteria- antibiotics. Bacteria can be treated and killed, where as viruses usually have to run their course and last their life span. Our white blood cells can help, but they don't kill the problem.
The size has nothing to do with it. It's the genetic make-up of the cells themselves.

Viral diseases are harder to beat because unlike bacteria, they have no metabolic processes of their own. When we give some kind of antibiotic, it actually disrupts some part of the bacterias necessary biological processes to continue living. A virus however may choose to reside in a part of our body that our own White Blood Cells do not want to attack. Herpes Virus for example hides out and replicates in our bodies nerve cells. Since our body does not want to kill its own nerve cell in order to kill the virus, the virus remains in place to replicate more virus and invade more nerve cells. Thats just a small example, here is little more in depth. Not all virus live in nerve cells.....
They do not respond to antibiotics or even antivirals because viruses are mutational, they modification their capacity of virulence (attack)...that's why when it's rugged to get over colds because nearby is no medicine that can certainly cure it or stop it...but rather alleviate the symptoms. because they spread trough the upper air, bacterial infections only by contact, you don't entail to touch the infected person, but you have need of to breath Because antibiotics can only be used to treat infections cause by bacteria.However, some infections own become resistant to (unable to be treated by) certain adjectives antibiotics. As a result, these infections are now more difficult to treat than contained by the past:
Staphylococcus Tuberculosis,Gonorrhea,Salmonella">aureus,Tuberculosis,Gonorrhea,... and
Streptococcus pneumoniae.
Colds,Flu,Most coughs and bronchitis and Sore throats (except for those resulting from strep), are adjectives caused by virus Because there is no drug even so that has be discovered that can kill a virus. Unlike microbes which has adjectives sorts of antibiotics capable of massacre bacteria. Interferon is a hot viral neutralizer but its efficacy is very set or sometimes nothing at adjectives. To treat viral infection, the body has to form antibodies against it and if ample antibodies has be formed slowly the virus will be neutralized. However this is not the shield all the time because nearby are some viruses approaching AIDS virus or Viral Hepatitis Virus wherein the body is unable to produce antibodies so eventually the party dies. Virus is not always detected due to second-rate information on data.Plus cycle of a virus usually completes beforehand it disappear. They do not respond to our antibiotics unlike bacteria virus are not considered living organisms
they are tiny units of protein
we know how cell including bacteria work
A cell is a stand-alone living entity competent to eat, grow and reproduce
virus are nothing similar to that
infact they are extremely tiny particles that are not efficiently seen even lower than some microscopes
they are smaller than bacteria and the cell in our bodies
thousands of times smaller
" a virus must own a host cell in which to live and fashion more viruses.
Outside of a host cell, virus cannot function.Unlike human cells or microbes,
viruses do not contain the chemical machinery (enzymes) needed to convey out the chemical reactions for existence. Instead, viruses pass only one or two enzymes that make sense of their genetic instructions".
so after all is said,
how do you take out the virus without massacre the cell and eventually the person who's cell have be infected ?????????
also, it is hard to treat viral infections because virus change their makeup, they mutate every in a minute and then one years virus is totally different from the subsequent years'
meaning what ever solution
( mostly vaccines)
might hold been used the previous year, will not be decisive the following year
the vaccine works by stimulating the bodys immune response to the virus.
it is made from a weakened,altered or kill virus and helps by sensitizing your immune system to that picky virus and
therefore creating imperviousness
viruses may move from one cell to another minus necessarily entering circulation which also adds to the complication contained by treatment
the list go on.....................!
to sum it up viruses are tiny complicated,persistent and stubborn horrors

You are on the right track. Viruses are more difficult to treat because they are able to use our host cells to replicate themselves and spread very quickly. With bacteria, they can replicate themselves very quickly but they do not enter our own cells. Viruses also have a very high mutation rate. Most mutations are either meaningless or destructive to the organism, but viruses replicate so many of themselves that the few that have beneficial mutations are instantly selected for and quickly multiply. Thus they can generate resistance pretty easily. Also, viruses can infect our cells and then stay dormant within them until the time is right to spread. That means that a viral infection may no longer exhibit symptoms but still be laying dormant in the body. Thus far, the best way to avoid viral infection is to vaccinate and use the immune system to prevent the virus from infecting our cells in the first place.
