Computer Antivirus

We explain what computer antivirus are and what these programs are for. In addition, what types of antivirus exist.

They detect different threats such as viruses, malware, spyware, worms and Trojans.
  1. What is a computer antivirus?

Computer antivirus are pieces of application software whose objective is to detect and eliminate computer viruses from a computerized system . That is, it is a program that seeks to remedy the damage caused by these invasive forms of software, whose presence in the system is usually not detectable until its symptoms are evidenced, such as Biological viruses

During the decade of the 80s, with the emergence of digital information exchange technologies such as floppy disks and, later, the Internet, it became possible to put successive contact to numerous computers. This brought about the appearance of computer viruses, and then spyware, malware and other forms of harmful software that enter the machine without the user's consent and cause different types of damage. os: unconfigure key sequences, delete personal files, hijack private information, etc.

The remedy, then, was to acquire a computer antivirus, offered by various commercial programming companies to guarantee the monitoring, cleaning and protection of computers . In the absence of them, the user is at risk of damaging the system and also spreading the virus each time he copies a floppy disk or sends an email.

There is currently a huge offer of antivirus services, essential since we spend more and more time connected to the Internet, receiving and sending information from already unknown computers.

  1. What are the antivirus software for?

Currently, antivirus programs are for more than simply scanning and disinfecting a machine that has contracted a computer virus . They usually offer active monitoring services, to prevent full access of an infected document to the system, block unsafe web pages and delete risky files as soon as they enter the computer. This is often called active protection.

On the other hand, computer antivirus also deals with other pieces of unwanted software, such as spyware, malware or rootkits, and even hacking attempts. To do this, it has a firewall (remote connection blocking software) and a virus definition database, which is a kind of encyclopedia of known viruses.

  1. Computer viruses

Computer viruses tend to act anonymously.

It was never said who programmed the computer viruses, although numerous theories accuse the antivirus companies themselves of creating the problem and then selling the solution. The truth is that these viruses acted as a terrorist attack : anonymously and based on their own logic.

The magnitude of its damages to the system or the inconvenience caused to the user are variable, from the elimination of personal files to the sabotage of the indispensable processes of the system. Currently, due to the rise of Internet services, viruses often pursue the sequestration of useful life information, such as credit card numbers or intimate photographs, when there are no administrative permits to operate the computer remotely.

  1. Types of computer antivirus

Several types of computer antivirus can be identified, according to their operation:

  • Identification Antivirus Those that track active sequences associated with certain viruses, but are not very effective in dealing with unwanted software. They have the virtue of being very light, some run from the network.
  • Antivirus decontaminators . Usually installed on the system like any other application software, these programs can be activated at will to check the entire contents of the computer for viruses. If there are, then, we proceed to disinfection and, if not possible, quarantine or erasure.
  • Real-time protection antivirus . Those that provide constant protection to the system, without having to carry out a thorough review, but reviewing all incoming and outgoing files and connections. These antivirus are usually combined with decontaminating functions.
