Virus is one of the most common Spanish words of everyday life. It is a masculine noun, whose plural form is the same as its singular version: virus. Therefore, this word does not change, but is written in the same way both in the singular and in the plural.

- It is a computer program that is surreptitiously introduced into the memory of a computer that, when activated, affects its operation, totally or partially destroying the stored information.
Etymology of the word virus
The word virus comes from the Latin term virus , which means “poison” or “poison”. This, in turn, derives from the Greek suffix – ios and the Indo-European weis -, which also mean “poison”.
This word was included in the dictionary at the beginning of the 19th century. However, until then it was used to refer to a poison, a harmful substance or secretion.
It is believed that one of the first uses of this word occurred in the first century BC, when the Roman writer Aulus Cornelius Celsus used it to describe a property of saliva that transmitted rabies.
It was after 1892, when the Russian scientist Dimitri Ivanovski discovered viruses, that this term began to be used with its current meaning.
