Spyware is a word of English origin, whose meaning or translation into Spanish is "spyware". Spyware is a term used in the field of computing and is used to refer to certain types of "malicious" programs, for this reason they are also called malware, Spyware can enter our computers without realizing it, and spy on all our personal information from within, they can also cause changes in our computers configuration and operation without permission. Spyware infects the operating system of the computers, preventing its normal functioning, and therefore its performance also declines.
These malicious software when entering computers are capable of collecting valuable and confidential information and sending it to other devices without prior warning to the owner.

Spyware are generally installed through internet pages that are not secure, through the installation of free programs also downloaded from the net that are apparently harmless, they can be accompanied by a virus or a Trojan that spreads via email, among others. The type of information they can obtain is very wide, they are usually the type of software installed, messages, email, telephone, contacts, keys to different applications, credit card numbers and bank accounts, what type of purchases are made online, IP addresses, among other. Spyware are considered "parasites", since they install themselves on the computer (in the RAM memory) and consume its resources and reduce its stability.
It should be taken into account that Spyware are not viruses, their use is more towards commercialization, since the purpose of obtaining all your information "illegally" is to study which products and services you might be most interested in. These spyware are very common, most computers can have it, however, do not be so alarmed since eliminating them is very easy.
