What is an antivirus and what are these computer programs for?
The first thing we must define is the term “malware”. This is a concept that refers to a set of computer programs that are dedicated to damaging the operating system, with different software installed on the PC, to extract important information and spy on user activity. That is to say, Within this large set of malicious programs are viruses, spyware, adware, worms and many others..
They are created by people or companies that pursue a certain purpose, usually criminal. They are characterized by being installed on the computer without the user detecting your presence. In addition, they need the help from users themselves so they can enter the device.
Accordingly, we can emphasize that the media Preferred of these malicious programs are emails and files that are shared from dubious sources. Once we have clarified what malware and viruses are, we can say that an antivirus is a computer program that is dedicated to detect all these malicious software.
They do this in real time and need permanent updating in order to find the latest malicious files. It’s easy to use. Must be install the antivirus on the computer and configure for it to run on background constantly. This will cause that whenever there is an eminent danger, the program will notify the user of this risk, thus preventing access by any malware.
Antivirus history and evolution How have they changed over the years?
In 1984 Reaper was determined to be the first antivirus. This program was born in 1972 to combat the virus that infected computer networks, called Creeper. Although its operation is similar to what we know today as a worm or “Worm”, since you could replicate alone e install on other computers, the objective was to analyze the data chain of the infected computer to extract and remove the virus.
If we consider antivirus as we know it now, we can say that the first one was launched in 1988 and was intended to remove the virus, released the previous year, called “Brian” Which affected the performance of the hard drives and it was transmitted by email with messages from trusted contacts.
The antivirus c systemIt consisted in comparing from a database the name and extension of the files that could be at risk for the computer. Currently, the antivirus they not only analyze and do that task, but also control the lines of code of the programs to prevent any dangerous file can enter the computer.
How does an antivirus work to protect us? Main operating methods
Updating antivirus is a key issue so that these programs are efficient in the care of the computer. This is because, in each patch or new version, a list with renewed information of new viruses and malware that have been created in recent times. This database is necessary so that the antivirus can compare it with the programs that you want to enter into the computer..
I mean, every time you need to download a file the antivirus compares that information with its database, if it finds something suspicious it does not allow the entry and a warning. From this it appears that, when comparing the files that are on the computer (or those that you want to download to the device) with your dictionary carries out different types of Actions.
These are:
- Repair the infected document, completely eliminating the virus. In this way, it puts the information that this file has into operationally.
- In case of can’t repair it as in the previous point, quarantines him. In this way, it blocks access to the computer, but does not eliminate it.
- Perform a permanent scan of the files that have a system to detect suspicious behavior.
What are the differences between an Antivirus and a Firewall?
The firewall is software that is installed on a device which connects to a network to manage the entry of data packets. Your job is to compare the flow of information with different protocols that were assigned beforehand. In other words, if information does not have the parameters required by the firewall, it cannot pass to the computers on the network, even if it is not malware.
From this it appears that if a virus can meet the protocol You will be able to enter any node that is part of the network. The difference that exists with the antivirus is that the latterdoes not take into account pre-assigned security protocols, but is dedicated to the analysis of malware according to their database and then erase them of the computer. You can install a antivirus and a firewall in any node that is part of a network or they can be placed directly in a router.
