How to know if my computer has a virus

Signs That There Are Viruses On Your Computer

On many occasions we notice that our computer has virus. We observe that something strange has happened and we suspect that we may have been the victim of some type of attack, some strategy that cybercriminals have carried out to take control. What are the main signs that can help us understand that there is malware on a computer? Let’s see the main ones.

Malfunction and slowness

Without a doubt a fundamental clue is to see that the team is slow, which is not working properly and we have trouble working. Each one is aware of the computer they have, of the capacity they have to make it work better or worse. Therefore, if we suddenly see that something that we used to do easily and quickly now takes much more time, it could be a malware problem.

Let’s say, for example, that the startup of Windows or the operating system that we use now is very slow. Or maybe we open the browser and notice that it takes a long time to load, that it is constantly caught, etc. All this can tell us that there are viruses on the computer.

Does not respond to orders

It could also happen that do not respond appropriately to the orders we give. For example, we try to open a program and it does not open, we delete a file and it is not deleted, we open the configuration and it automatically closes, etc.

It is a sure sign that something is wrong. It is most likely due to one of the many varieties of malware that could compromise our devices. We would need to take action and reduce risk.

Programs that we have not installed appear

Of course, another point to keep in mind is when programs appear that we have not installed. Let’s say that suddenly we see icons on the desktop of applications that we do not use, that we do not know why and when they got there.

Sometimes malicious software installs programs without our consent. We can also go to the applications menu and check if there is something added that it shouldn’t. All this can help us to know if our computer is infected.

Bad internet speed or outages

We can see all this reflected at the time of surfing the Internet. We can see that the speed is not adequate, that there are cuts and instability. We could have intruders on our computer consuming network resources. For example, a Trojan that serves as a gateway.

Configuration has been changed

Have we noticed that something about our team has changed? It is common for computer viruses to make certain changes in the setting. We might notice that certain parameters have disappeared or that the device does not act as before in certain circumstances.

The antivirus is disconnected

This point is also very important. There are many security threats that the first thing they do once they infect a computer is disconnect the antivirus. Ultimately in this way you can act without being detected, you can carry out certain changes. It could even happen that the antivirus is uninstalled.

How to prevent viruses from entering

We have seen some of the main signs that can tell us that our computer has malware. Some reasons that would make us think that there is a virus affecting the proper functioning. Now we are going to give some important recommendations to keep the system protected and prevent cybercriminals from sneaking some type of malicious software.

Always keep systems up to date

Something essential is to always have the correctly updated equipment. On many occasions vulnerabilities can arise. These security flaws affect all types of equipment, the operating system or programs that we have installed. They can be exploited by hackers to carry out their attacks. Hence, we must always have all the patches and updates that are available.

Install antivirus and firewall

It will also be essential to have a good antivirus, as well as other security tools as it could be a firewall. This will help keep cybercriminals who try to infect your computers with viruses.

Keep in mind that we can count on a wide range of possibilities. We have both free and paid antivirus and also available for all types of operating systems. We simply have to choose the one that best suits our circumstances.

Web security

Download only from trusted sources

The way we install programs can also reduce the risk of viruses. We must always choose sources that are official. We must avoid installing software from third-party sites, where we do not really know who may be behind it and how it could affect us.

Check that everything is in order

In this case, what we are going to do is check that everything is fine. We must analyze the installed programs, the browser extensions, check that we do not have dangerous files, etc. All of this will help avoid the risk of security attacks.

Common sense

On the other hand, another point we want to mention is common sense. Is essential not make mistakes. We must avoid downloading email attachments that can be dangerous, not installing software from insecure sites or using strong passwords that prevent intruders from entering. This will help us avoid being victims of malicious software.

Therefore, by following these tips we can prevent our computer from having viruses. It is very important in order to preserve security, to reduce the risk of malware that in one way or another affects its proper functioning. All this will make the speed of use, the connection and the different functions go smoothly.
