Why Does Antivirus Blocks VPN and How to Avoid It

What causes the VPN to be blocked by the antivirus

When we encounter the problem that we install a VPN and the antivirus blocks it, the main cause is that it detects that it is a virus. The security software will alert us when we install software that could become dangerous and, in the case of VPN, this can happen. Of course, we are most likely facing a false positive and the application is not a danger.

This which we mentioned especially can happen when we install a VPN that is not reliable. For example, a free program, which is not reputable and can be seen as a real threat by certain security tools.

It may also be that we have installed an additional add-on to the VPN. It usually occurs in certain programs that additionally offer us additional tools, such as antivirus, antispyware or other software in charge of security.

On the other hand, it is common for an error to appear in the VPN itself. For example, a corrupt file after updating the application. This could lead to conflicts that alert the antivirus and consider it as a threat, even though it is safe.

Generally, the problem is usually in the antivirus, but we could also see that it is the firewall that is blocking the application. This would prevent it from connecting to the network, so we would have to configure it correctly and prevent this from happening.

Steps to avoid VPN blocks

So what should we do to prevent the antivirus or firewall from blocking the VPN? We are going to explain the main steps we must take to prevent this from happening and to make it work correctly, we can connect to the Internet and encrypt the connection normally.

Use a reliable VPN

The first thing to keep in mind is that it is very important to use a VPN that is reliable, works well, and has all the guarantees. On the one hand, it needs to function correctly and fulfill its mission, which is none other than to hide our IP, encrypt the connection and allow browsing more privately.

But it is also important to use a correct program so that the antivirus does not detect it as a threat. If, for example, we use a free application that does not meet the minimum guarantees, the security tools will likely jump and tell us that what we have installed is not to be trusted.

Therefore, our advice is always to avoid VPNs that are free and focus on those that do offer guarantees both of good operation and also for our privacy and security.

Update the program correctly

We must always have the programs properly updated. This will help us to function optimally, have all the improvements available and also avoid problems. But especially in those applications that connect to the Internet, it is even more important.

If we have an outdated program it could lead to security problems. But also, if that update has not finished, it could generate conflicts or that there are corrupted files that in turn are the reason why the antivirus detects it as a security threat.

Reinstall if necessary

In case it is necessary, as long as we see that the antivirus continues to detect the VPN as insecure and we have updated it correctly, we could try to uninstall it completely and reinstall it from scratch, making sure that the process is successful.

In many cases, this is the best solution when problems of this type arise. If, for example, there has been a corrupt file that has not been corrected well with the update, this will allow us to solve it and return everything to normal.

Verify that the firewall does not block the program

Windows has its firewall, in addition to antivirus. But we can also install third-party versions. Whichever option we use, it may be blocking the connection and the VPN cannot connect to the Internet normally.

Therefore, what we are going to do is verify that the firewall is not blocking our VPN. For example, in the case of the Windows Defender firewall, we can open the program, Advanced Settings, Outbound Rules and see if our VPN is on the list of blocked programs.

Avoid additional plugins

Sometimes VPNs when installing them offer us certain add-ons that may seem interesting. For example adding an antivirus that comes with the application, an antispyware, an extension for the browser that offers security ... Although they are not bad tools by themselves, the truth is that they can generate conflicts.

Therefore, our advice is to avoid this type of add-ons. If, for example, we install another antivirus, this usually generates conflict and causes errors. The main antivirus can interpret it as a threat and not allow us to navigate correctly.

Use a good antivirus

But the problem may not be with the VPN, but with the antivirus itself that we are using. Is the program we have installed good? We must always make sure that it works correctly, is properly configured, and will not generate any kind of problem.

Which one should we use? Microsoft works very well on Windows, but there are other popular alternatives such as Avast, Bitdefender, or Kaspersky. Whichever option we choose, our advice is to use recognized programs,  get informed very well of their characteristics, and that they are also updated correctly to reduce problems as much as possible.

Ultimately, the fact that the antivirus detects a VPN as a threat is a major problem. We must control our equipment and the tools we have installed. Only in this way will we ensure that surfing the Internet is not a problem and avoid the conflicts and false positives of security that can alter so much the connections in our day-to-day life.
