Your antivirus does not work against these threats

When the antivirus does not protect

Programs such as Avast, Windows Defender, and many others that we can install on the computer and mobile can prevent the entry of viruses of all kinds. However, they don't always work. There are even certain very dangerous threats for which they will not be able to act. There we will have to take other measures, such as updating the system or avoiding making mistakes.

Phishing Attacks

One of them is Phishing attacks. In this type of attack, a hacker sends an email or SMS posing as a legitimate page, an official service such as a social network, email, or any platform. Usually, they usually throw a hook in which they ask us to make some change or solve some error.

For example, something usual on these dates is that we receive an email where they tell us that a supposed order that we are waiting for has had a problem and we must update data or do something. The victim clicks, puts their data in, and unknowingly sends it to a server controlled by the attackers. An antivirus could not act there.

Vulnerabilities in the system

Another problem that an antivirus will not be able to protect us from is vulnerabilities that exist on the computer. There may be security flaws in the operating system, in some applications that we use, network adapter drivers ... This could be leveraged by a hacker to launch their attacks and take control of the computer.

In this case, the antivirus would not warn us. What we are going to have to do is control that we always have the latest versions installed, that we do not leave any outdated program or any adapter without the latest version of the firmware, and have a gap there. This can lead to RDDoS attacks, for example.

Entering a fake domain

By browsing the Internet we can reach pages that are actually fake. For example through a link that we see on one site that refers us to another. We think it may be original, but it's actually a page they've created just to collect personal data and put our security at risk.

To avoid problems of this type, the idea is to check the URL to which we are entering. We must check that the address really corresponds to the place we are trying to enter. For example, if we are going to access Facebook, it is essential that we see that the domain address is correct.

New viruses

Antivirus has a database of known threats. In this way, if for example, we download malware on our computer, it warns us of it and eliminates it. What happens if it is a new virus which has not yet been detected? In that case, it could not protect us.

Therefore, to be fully protected from this type of problem, common sense will be very important. We must avoid making mistakes, such as downloading applications from sources that are not reliable or entering sites that may be dangerous.
