When creating a virus, you should think of the following:
* What will it exploit? How will the virus enter a computer and not be detected?
* How will the virus infect other programs? Is it a non-memory residential virus or a memory-residential virus?
* How fast will it infect the host computer? In other words, will the virus spread extremely fast to destroy the computer as soon as possible or will it spread more slowly to make sure it is not detected by antiviruses?
* How will the virus conceal itself? Will the virus infect antivirus programs to avoid detection, use polymorphism, or some other stealth function?
Asking these questions allows you to have what virus in mind you want to make and lead the way to making the perfect specimen.
Computer viruses are developed with the help of different codes, strings and scripts. They are developed to destroy something or to hack or steal some data.
It is not possible for there to be no viruses because viruses are simply programs that do malicious things. Viruses can also be developed accidentally by flaws in the coding of a program that causes undesired effects though this is rare.
Facebook in itself cannot give you viruses. However, clicking on the advertisements, or using applications not developed by Facebook or a trusted company potentially can.
Antiviral drugs are most often designed and developed to combat specific viruses and sub-categories of viruses: HIV, Flu, Herpes, Shingles, Cold sores, Canker sores, etc.
Viruses could not be seen because the resolution and magnification was not good enough until 1938 when Ernst Ruska developed the electron microscope.
because then the technology was not developed and people had all the beliefs......
because viruses responsible for viral fever are many and mutate very rapidly.
The best treatment for a virus is rest and symptom management. Antibiotics will not affect viruses. Vaccines against several viruses have been developed which bolster the immune system, and there are antiviral treatments for severe cases such as HIV.
Viruses are classified differently than living organisms, since they are not technically alive. In taxonomy, viruses are not assigned to a Domain, Kingdom, Phylum, Class, or Order. The influenza viruses start, in most classification systems, at the level of the Family. They are in the Family of Orthomyxoviridae. There are a few newer classification systems that have been developed to better categorize and classify viruses, but these are not yet the standard.
Apparently this can happen with MMORPG games. They really have files that send information over the internet, which is a part of their normal behavior and is not meant to harm you in any way. But antiviruses detect them nevertheless.
Computer viruses, Macro Viruses, and Directory Viruses
No. Viruses have to start somewhere it just happened to be in Mexico. In more developed countries these things get noticed more quickly though.
