These are the types of viruses that will attack your pc if you do not know how to avoid them

Everything related to security in our equipment is a recurring theme that should concern us more and more. Hence, at this time it is almost essential that we have an antivirus installed to protect the data and applications on our computer. More if we take into account that there are many types of viruses and malware that may be stalking us.

This is something that has become even more important after the advent and expansion of the Internet. As you know, the network is full of information, photos, videos and all kinds of elements we may need. But it also has its negative points, as with malware that also runs online. Hence precisely the many precautions that we must take to avoid the arrival of these elements.

What are viruses

For example, it is increasingly important that we properly configure the Internet browser that we use. And it is that these software elements increasingly have a greater number of customizable parameters that can be very helpful in this regard. Thus, from the browser itself we have the possibility to block malicious downloads, avoid web crawling, etc.

All this in order that, as far as possible, the malware reaches our computers. With everything and with this it is also important that we have some type of antivirus that protects us against all kinds of malicious elements that may reach us. This can not only happen through the Internet, since it can reach us from any route. It is something that we have commented on countless occasions, and it is also an issue that we must bear in mind.

And it is that it can be said that, in one way or another, everything related to security on our devices is something that we cannot forget or put aside. In one way or another, malware constantly stalks us and wants to take over our private data. It is true that at first all this could sound a bit like a horror movie. But the truth is that computer attacks, whether on our desktops or mobile devices, can unintentionally give us an upset.

Viruses vs malware

As time goes by, we are dealing with more and more sensitive data on these computers, which is why cybercriminals always seem to be one step ahead of security companies. These are the ones that provide us with their solutions designed to protect us against these viruses and other malicious code.

We tend to confuse both terms, malware and virus. Well, it should be mentioned that malware is a term used to describe any type of malicious software or application regardless of its action. However, a virus is actually a type of malware with particular characteristics that differentiate it from other malicious software. In addition, the concept of malware or malicious code includes several categories of threats that we will see below. Each of them are shared by other threats where a virus is one of these.

Other threats

As expected, as the Internet has become an increasingly active part of our lives, the attacks are intensifying. In fact, the various types of malware have grown exponentially, with their risks. In this way, it could be said that news about new attacks or dangers in the form of ransomware, worms, spyware, etc. do not stop coming out almost daily .

Something we should know is that although many speak of viruses as a general term for all types of infections, this is not entirely correct. It is true that when talking about viruses in general, the most widespread name of these specific elements is given. In this way and with this nomenclature, what is really achieved is to cover as many types of malicious code as possible. However, when it comes to generalizing, perhaps the most correct thing to do would be to talk about malware.

Types of viruses and malware that can attack us

But something that we must bear in mind is that below malware in general, there are many other different types derived from it. That is why we will see some of the most widespread and well-known below. This will help us to distinguish between the most common in these environments, both on the Internet and on our computers. Thus, depending on the type of task that the malicious code intends to carry out on the infected system, it will belong to one group or another.

Viruses: what are they

To begin with, we will tell you that when we talk about a computer virus, we are actually referring to a very specific type of malware. This is the one that attacks those applications that we already have installed in the operating system. However, contrary to what happens with so-called worms, these viruses need the user to act so that they spread throughout the system.

Of course, if we are aware of it or through some kind of deception, viruses have to be activated in some way by us to make them work.

The worms or worms, how they act

On the other hand we find the aforementioned worms . You could say that these are a variant of viruses, but a little more dangerous. The reason for all this is that at first the worms do not require our interaction to infect the system. The main reason for all this is that once they are installed on the computer, by themselves and independently, they begin to spread throughout the computer.

As a general rule, they start with the main memory of the computer, going to the disk units and therefore to the programs and data that are stored here. This propagation can only be stopped with an antivirus that eliminates the aforementioned worm.

They are standalone malware, without files, and they spread using a stealth methodology. Common delivery methods for worms are email or instant messaging attachments. Users are led to believe that these attachments are safe to open and they sneak through USB drives as well. However, an effective way to prevent all of this is to avoid opening some strange email attachment.

Since worms are self-replicating, they use a lot of free space on your device, so if we notice a sudden drop in hard drive space, it may be caused by a computer worm. At the same time, these elements block many programs and make the computer run slower than usual. In fact worms can delete, replace and create new files.

The first worm known as Jerusalem was discovered in 1987 and there are several types such as Internet, email, instant messaging, file sharing, etc. As we say, the best way to prevent their arrival is not opening strange attachments or from unknown sources. We should also know that if we have doubts, it is best to use some type of antivirus, they detect most of the guanos.

Adware, ads, and pop-ups

Changing the third, another of the types of malicious code that you have surely heard on many occasions, is the so-called adware. This is another format that has spread more and more over time. The first thing that we must bear in mind here is that unlike those mentioned above, this does not try to damage our computer as such. What adware actually does is bombard us with unwanted advertising.

This affects a multitude of software elements that we have installed on the PC . The worst thing about this specific format is that the arrival of unwanted messages and advertising is such that it saturates the computer. This can be translated into that sometimes it leaves the web browser and the system in general, almost without being able to use it.

Ransomware: data hijacking

It is very possible that one of the malware formats that are spreading the most lately is the so-called ransomware . Actually here we find a malicious code whose main task is to hijack all the data that we have stored on our hard drive. Then, once access to our data is blocked, the malicious code itself is in charge of asking for a ransom, usually cheap . This, in theory, will help us to use the equipment again.

But of course, this is not always the case, even if we pay the ransom as such, therefore it could be said that ransomware is full-blown blackmail and we do not recommend paying it ever. Hence the importance of backups that we talked about so many times.

Spyware, its dangers

On the other hand, we find another of the most common, spyware, which, as its name suggests, is a type of malicious code in charge of detecting sensitive PC data. Elements such as access credentials, credit cards, passwords or bank accounts come into play here. Therefore, once the malicious code is done with all this, it forwards it over the Internet directly to the attacker to dispose of this sensitive content.

Finally, we are going to refer to “Trojans”, an element that without wanting to damage our system, at least directly, “opens a door” in it so that other types of malware can access without problems, or at least in a simpler.

Trojans: a back door to your PC

We also want to talk about the so-called Trojans, an element that without wanting to damage our system, at least directly, open a door to it. In this way, what is achieved is that other types of malware can access it without problems, or at least in a simpler way.

Hence, they are considered one of the most dangerous and important of all that we can find in these times.

Cryptojacking, cryptocurrency mining

One of the types of malicious code that is spreading the most in recent times is Cryptojacking or mining of cryptocurrencies . In reality it is a malicious cryptocurrency mining that is carried out taking advantage of our PC, without us noticing. Thus, what this does is make an illegal use of our equipment and its components, to extract digital currencies through the Internet.

Therefore, this could be considered as the violation of a computer although with no other objective than to mine cryptocurrencies by hijacking certain resources of the PC.

Exploits, taking advantage of flaws and weaknesses

An exploit is malicious code that actually takes advantage of a bug or vulnerability to cause unexpected behavior in software. Likewise, exploits can affect hardware components or any device. It is worth mentioning that these behaviors include taking control of a system completely. In the same way, these affect the administrator permissions of the programs.

Fake antivirus, more bad than good

As its name indicates, fake antivirus are small programs that we consciously install on the computer thinking that they are going to protect us. These are usually offered many times when we surf the Internet and are sold to protect our equipment from a potential evil that is already affecting us. In this way, if we fall into the deception, what we actually do is add malicious software to the system that will try to take over the personal data stored on the computer.

Therefore, as you can imagine, this is something that we must try to avoid at all costs.

Riskware, dangerous programs

And changing the third, we find Riskware . Actually, this is the name given to legitimate programs that can cause damage to the PC. For this it has to be used by malicious users to delete or modify stored data, as well as to copy them for malicious purposes. These elements also negatively affect the performance of the PC, all this to take control of it.

How to protect ourselves and avoid malware

Here we have talked about the main types of malware that can negatively affect our PC in one way or another. That is why, as you can imagine, this is something that we should try to avoid as much as possible. To do this, as we mentioned before, we can try to use various security solutions, such as antivirus. But we must also do our part so as not to put our PC in danger.

This can negatively affect our private data, installed programs, etc. Not to mention the damage it can do to the operating system as such, for example. That is why we will also talk about some elements and behaviors that we must take into account to protect ourselves from malware.

Antivirus

As we mentioned before, this is a specific type of software that has become one of the most important. In fact, it could be said that nowadays it is unthinkable to connect to the Internet without an antivirus installed on the PC . And it is that more and more threats are hiding here and looking for an opportunity to get hold of our data. But we must install an antivirus, or use the one that integrates Windows 10 by default, we refer to Windows Defender .

It is worth mentioning that there are many security programs that we can use in this regard. These antivirus that we are talking about will be very helpful when it comes to being protected when using the computer. There are dozens of totally reliable solutions of this type, some free, some paid. You just have to choose the most appropriate in each case.

Update the PC

The attackers are on the lookout at all times, that is something that we must be more than clear from the beginning. That means they are constantly trying to get hold of our data. To do this, they take advantage of the slightest loophole or security hole. Either in Windows itself, or in some of the installed programs, these may have security flaws.

Hence precisely the importance of updating all this as soon as possible. And it is that software developers, including Microsoft, take advantage of these updates that they release constantly to patch those security flaws, hence the importance of these. Therefore, updating both Windows itself , as well as the programs that we use in it constantly, will help us a lot to avoid unnecessary risks.

Visit secure websites

Our behavior on the Internet is also key when it comes to preventing some type of malware from reaching our computers. To do this, what we must do is avoid certain web pages that we consider suspicious. And you have to know that many of them are available to, in one way or another, maliciously access our computer.

They use several avenues for this, which are the ones that we really must avoid at all costs. For example, they offer attractive programs for us to install. At the same time they offer certain content that could be attractive to us, or even gifts if we click on certain links. Well, all of that is what we really need to avoid if we want to stay away from all those types of malware .

Avoid piracy

Piracy of all kinds of content on the Internet has been with us for decades. In addition, the methods for all this have been updated over the years. Hence, little by little these behaviors have spread throughout the world. But despite its appeal to many, attractive but illegal, it also carries many dangers. And it is that piracy is also used by attackers to access our computers through those downloaded content.

For example we can install programs in principle of payment, but for free, which are actually malicious programs. This is one of the most common techniques here to maliciously access our computers. That is why, among many other reasons, we should avoid piracy at all costs so as not to install malware on the PC.

Have common sense

Although it may seem a bit obvious, common sense when working with a computer will also be of great help when it comes to protecting ourselves. With this, what we want to tell you is that we take certain logical precautions that will surely help us when it comes to preventing the arrival of all kinds of malware. For example, we should not trust email links that come to us from unknown sources. It is also important to know that on the Internet no one gives away phones, programs, or trips without looking for something in return, plus somewhat suspicious pages. All this is nothing more than strategies that are carried out to deceive us and so that we click on malicious links, for example.
