Antivirus Knowledge

Both firewall and antivirus software are security mechanisms designed to protect your system. A firewall is a low-level network security system designed to protect your system and network from malicious damage. Antivirus, on the other hand, is a software utility program designed to protect your computer from insider threats like viruses, malware, spyware, etc. The purpose of a firewall is to restrict any unauthorized access to the system by monitoring network traffic inside and outside the system. It inspects the flow of data from the Internet to the system to decide which should be allowed and which should be restricted. The purpose of an antivirus program is to detect, scan, prevent, and remove harmful programs that can compromise your computer. Typically, a firewall works at the network protocol level to protect public and private networks from unwanted intrusions. Setting up a firewall has its benefits, but it also has its drawbacks. It can only prevent unauthorized access betwe

In this article I will explain what WannaCry malware is (in Spanish "I want to cry"), why it is dangerous, how to protect yourself and how to fix it if we get infected. What Is the Wanna Cry Virus? WannaCry is a massive computer virus type 'ransomware' (which encrypts computers) that is infecting computers and internal networks of large companies in the world. The virus affects Microsoft's Windows system and has infected computers in more than 150 countries that did not have the latest updates installed. The Wanna Cry virus restricts access to your system and demands a ransom of $ 300 in bitcoins be paid to its owners to remove the restriction. The computer attack has already gone down in history as one of the most aggressive and, at this point, affected computers have been reported in more than 100 countries. The electronic means of payment (bitcoin) has been selected as the means of payment since it allows the anonymity of the person receiving the money to b

The existence of computer viruses is no longer nothing new. Some collect information illegally and others corrupt files and programs. In the most extreme cases, they directly destroy computers, affecting the hard drive and rendering it completely unusable. Therefore, it is very important to know how to detect computer viruses and eliminate them completely. In this blog we are going to explain everything you need to know about it. Computer Virus Detection Detecting computer viruses early can be crucial to keeping programs, information, and even computers safe. At the first symptom, take measures so that the virus does not cause the total loss of valuable information and render your computer unusable. Some of the key clues that can help you know how to detect computer viruses are: Speed: Computers lose speed over time, components age and deteriorate. However, the useful life of a computer or electronic device is more likely to end due to becoming obsolete than due to malfunction. If

Invisible is a term used to describe techniques that allow malware to go unnoticed, that is, to hide all the changes it makes to the infected system. It makes your device unhealthy and make it unavailable for doing any work. It does nor connect to internet and many more unusual things. This type of malware includes, for example, rootkits. How Invisible Viruses Infect Computers An invisible virus can infect a computer system in a number of ways, such as when a user downloads a malicious attachment in an email, installs malware that impersonates website programs, or uses unverified and malware-infected software. Like other viruses, invisible viruses can take over a wide variety of system tasks, and computer performance can suffer. When performing these tasks, antivirus programs detect the malware, but the invisible virus is designed to remain hidden from antivirus programs. To do this, it is temporarily moved out of the infected file, copied to another drive, and replaced with a clean

Today’s blog is interesting. You already know me and you know that I love to help you and make your life as easy as possible. Today I am going to teach you, easily and quickly, how to detect, avoid and eliminate viruses and malware. The world of 'computer viruses' has also continued to evolve in recent years. This has ended up giving life to a new fauna that is becoming more extensive and dangerous. What Is Malware? Formerly called computer viruses, today they are more technically known as 'malware' (malicious software).

Having an antivirus in Windows is not only recommended but is almost essential, although Windows Defender can suffice in many situations. However, total protection does not exist, as the newly discovered ransomware demonstrates, with the potential to uninstall the antivirus and thus leave the way to act. This new type of ransomware is still in development, because as security experts have been able to verify for Bleeping Computer, it does not achieve its objective. It cannot uninstall the antivirus -not all, of course- or encrypt the files. It also lacks instructions to pay the ransom, although in its sector it can be described as promising. The danger of this malware is not the damage it can do, but what could happen if it creates school and becomes a model for the next generation of computer hijackings. That the next versions of ransomware can uninstall the antivirus before encrypting the files on your PC is not at all reassuring. In addition to being ransomware, it could also
