Today it is unthinkable use the computer without the protection of a good antivirus.
These shield programs They are constantly updated to ensure the proper functioning of computer equipment, allowing the correct performance of operating systems and their coexisting applications.
But someone might ask:why antivirus was created?, What is a computer virus? And how could you know if my PC is well protected? We will answer each of these questions, so pay close attention.
Computer viruses are a series of commands or programmed instructions and packaged that have the purpose of modifying the correct functioning of the operating systems in order to destroy, steal or collapse the memory and the files contained in the computer. Cyber attacks can affect our privacy or the integrity of our documents.
As a curious note we can mention that at the beginning, when there was not a complete understanding of computer viruses, some companies prevented their employees from going to work if they had the flu to avoid contagion to their computers. Today we recognize that this is a total absurdity.
The creation of antivirus
Motivated to counter attacks by unscrupulous programmers, the companies responsible for the distribution of their operating systems they were forced to create software that would defend computers from computer viruses.
In this way, we can define that antivirus are programs specialized in attacking a virus by scanning, detecting and eliminating.
Antivirus must evolve as new viruses appear or old ones evolve.
The first antivirus created was Reaper in 1972, with the sole objective of attacking the virus called red creeper.
The globalization of computers and the arrival of the Internet exponentially increased computer attacks. However, today's antivirus have databases capable of attacking an infinity of viruses launched on the web.
There are many "brands" and types of anti virus, however, you should not just fall into the marketing they do, but you should know them better. We link you a comparison of the best antivirus on the market today that will probably help you to get an idea of how the issue is today.
Types of antivirus according to their classification
Due to the wide range of virus styles that have been presented as attacks, it has been necessary to create various types of antivirus.
Many of the companies dedicated to the creation of programs for the protection of computers, package all these functions in a single software or antivirus. However, we will describe the sub-functions per runtime below:
In anticipation of the infection, they do not allow access to any type of file that is detected as malicious. These require a memory space, to perform constant scanning for possible threats.
Takes care of identify contaminated files through the process of exploring and comparing a red-listed database.
This dedicated to rendering the virulent file unusable and then lock it in a trunk or, failing that, eliminate it completely. They are also capable of restoring the affected operating system to a previous state before the infection.
In addition to these classifications, the following types of antivirus also stand out:
- Antimalware. In charge of blocking and eradicating infiltration programs called malware.
- Antipop-ups. Detects and blocks pop-up windows from portals that are commonly used as spyware.
- Antispyware. Software specialized in identifying spyware that are installed without your consent to collect all kinds of information.
- Antispam. Integrated in many emails to avoid the avalanche of junk advertising emails or emails that can give entry to other types of viruses to the computer.
The best way to know if your PC is well protected is to make sure you have a good antivirus; preferably paid, which guarantees the inclusion of all levels of protection and that it is always up to date with updates from your database.
Certainly antivirus is strictly necessary to be able to enjoy a pleasant experience when using your computer, especially if the operating system you use is commercial, as they are usually the most attacked by computer viruses.
