Update on


Unsecapp.exe is not a strange program in your Windows operating system. Unsecapp.exe is a part of the Windows Management Instrumentation (also known as the WMI) subsystem.

As a Windows user, you don’t know intentionally open and work with it. However, it is utilized by the operating system itself for an important purpose in the background.


Unsecapp.exe is vital in establishing a communication line between programs in your system and corresponding remote servers. That means it becomes very useful, especially when you launch a program that requires the assistance of a remote server.

This is true, particularly regarding apps that work based on VoIP technology. Unsecapp, in this case, works as a tool that bridges the respective software and its corresponding server.

As mentioned at the beginning, the users don’t have to start unsecapp.exe by clicking or using any other technique. Instead, it will be started automatically when a program opens and tries to communicate with the corresponding remote server.

All the Windows operating systems except Vista have this tool to start only when required. However, in Windows Vista, the respective service automatically starts when the computer boots up.

An Overview of unsecapp.exe

As mentioned before, unsecapp.exe is a part of the Windows Management Instrumentation. This process is often called Sink by technicians familiar with the Windows operating system.

They identify as a callback validator designed to receive asynchronous callbacks directed at WMI clients.

The purpose of WMI is to allow software developers to write their scripts and programs. These programs are designed to run programs, user accounts, query devices, etc.

In addition, they are used to run Windows services and other internal aspects of your Windows OS. In this case, WMI is considered one of the infrastructure’s most important aspects. That is relevant to management data and operations on Windows operating systems.

When there is a program that requires the assistance of WMI programming, unsecapp.exe should be opened. In response to that, the operating system will trigger unsecapp.exe. This special tool will receive the results sent through WMI queries in your computer system.

Unsecapp.exe will play the role of a conduit (often called Sink). It will transmit the queries of WMI and relevant commands to the program that demands such a connection.

What If Unsecapp.exe Starts Randomly?

As we have mentioned before, unsecapp.exe is meant to start whenever a program requires to connect with its server. In Windows Vista, it opens automatically when the system boots. However, some users say that they notice unsecapp.exe starts in their systems randomly without any specific reason.

However, the truth is that it happens whenever a program communicates with the server. But you don’t recognize the program, and therefore, you think it happens without any reason.

For most users, this instance can occur after installing new application software. If that specific software requires connecting with an external server, unsecapp.exe will start automatically. As a result, you assume that it has started without reason.

This type of instance can happen specifically if you have installed VoIP-based apps on your system. For instance, applications such as Skype and Discord can trigger the OS to open unsecapp.exe.

In addition, gaming software like Steam and Origin can create such a requirement. You should also know that antivirus programs and messaging platforms trigger unsecapp.exe.

In a nutshell, unsecapp.exe will trigger whenever you open an application requiring a remote connection.

Interestingly, some users wrongfully think that unsecapp.exe is related to the Avast antivirus program. As a result, they tend to uninstall Avast antivirus just to get rid of unsecapp.exe.

Unfortunately, the unsecapp.exe will stay as it was because it is not a part of the Avast Antivirus Suite. The truth is that this specific tool can relate to any antivirus program, not just to Avast.

Is It Required to Remove Unsecapp.exe?

We want you to read this section of the article very carefully. If someone asks whether it is possible to remove unsecapp.exe, the answer is “YES.” However, we strongly advise you NOT TO UNINSTALL IT!

In other words, you should leave unsecapp.exe as it is, although you can get rid of it. Unsecapp.exe is considered to be a safe and required tool. If you’ve read this article from the beginning, you already know there is no requirement to uninstall it.

Also, you know that unsecapp.exe is required to start some of the essential programs in your Windows system. For instance, it requires starting your antivirus and Skype.

If you disable this service, the applications we have mentioned above may not be able to function properly. It is needless to mention, how catastrophic such instances would be. Even your operating system will start to function weirdly in that case.

Apart from the obvious hindrance it causes to the OS, it can even prevent third-party apps from performing properly.

If you have any app that requires access to WMI programming, that will start to malfunction. So, you should consider unsecapp.exe as a part of your operating system. You should not try to uninstall, stop, or delete it. Having that in mind, let’s move to the other section of this article.

When Can Unsecapp.exe Be Problematic?

As we have mentioned several times, unsecapp.exe is not a problematic or unsafe app. It doesn’t do any harm to the computer or your privacy. However, there are instances in which the name “unsecapp.exe” can be problematic for Windows users.

As you may know, plenty of malware programs come with various faces. Some malware programs can be disguised as legitimate programs in your operating system.

So, the same thing can happen to your unsecapp.exe as well. That means a malware application can disguise itself as unsecapp.exe and get installed in your computer system. It can be identical or very much similar to the name of the process. Then, it will silently sit in the operating system and do the damage for which it is designed.

Some of those tools can track down all the activities you perform on the computer. They can even track the passwords you type and send them to a remote server. They can even track your financial information and cause huge trouble.

However, the good news is that the newer Windows versions are not that vulnerable to those types of attacks. They come with advanced, sophisticated security systems to defend the OS from such malware attacks.

If you have an up-to-date Windows OS and a reputed security tool, you can protect your OS. In this case, a security tool like Windows Defender can be handy. Combining an updated Windows OS and a powerful antivirus program can eliminate malware disguised as unsecapp.exe.

However, if you are still doubtful about your computer’s security, you should take advanced steps. For instance, you can proceed by launching the Task Manager and checking if the file is original or not. To do that, you should press “Ctrl” + “Shift” + “Esc” together and bring the Task Manager utility.

Then, find the unsecapp.exe service and right-click on it. Choose the option called “Open File Location.” If the respective service is genuine and legitimate, it should be located in C:\Windows\System32\wbem. So, you can assume that the service is safe.


However, some individuals may still not feel confident with it even after checking the file path. In that case, the best move is to scan the specified file using your malware scanner.

You can consider using Windows Defender to get it scanned. Just right-click on unsecapp.exe first and select the option called “Scan with Windows Defender.” If not, you can use a different third-party malware scanner and scan the respective service.

If the file is located anywhere other than where you usually install programs, that’s very suspicious. It can be malware or spyware that pretends to be a legitimate tool in your OS.

However, the good news is that most antivirus programs can catch those culprits at once. So, if you don’t have an antivirus program installed on your PC, do it now. And be sure to have it updated regularly.
