Virus
Software that is spread by people, specifically user actions, usually through emails, websites, and chats.
A virus is a submicroscopic infectious agent that can only replicate inside living cells of organisms. They are made up of genetic material, either DNA or RNA, enclosed in a protein coat called a capsid, and sometimes also surrounded by a lipid envelope.
Viruses are not considered living organisms because they cannot reproduce or carry out metabolic activities on their own. They need to infect a host cell in order to use the cell’s machinery to replicate themselves. Because of this, viruses can cause a variety of diseases in humans, animals, and plants.
There are different types of viruses, such as the flu virus, HIV, measles, Ebola virus, and many others. Some viruses can be transmitted through the air, by contact with infected people or animals, by consuming contaminated food or water, through insect bites, or through sexual contact.
The best way to prevent the spread of viruses is by practicing good hygiene, such as washing hands frequently, covering the mouth and nose when coughing or sneezing, avoiding close contact with sick people, and getting vaccinated when available. In some cases, antiviral medications can also be prescribed to treat viral infections.
