 If you find the COM surrogate, it doesn’t necessarily mean that you have an infected computer. This article is all about how you kill the COM surrogate. 

What Is “COM Surrogate” (dllhost.exe), and Why Is It Running on My PC?

Component Object Model (COM) surrogate might be a dangerous variant of COM (COM). In order for Windows to function, it needs a file called the COM. The COM’s primary function is to monitor and generate Windows COM objects.

The hostile version, on the other hand, is full of nefarious schemes. A long time ago, hackers came up with the notion of hiding Trojan horses in plain sight.

For this reason, the dllhost.exe in question The dllhost.exe 32 COM surrogate malware is then referred to as such. Using this method, hackers are able to get access to computers and steal data, as well as money. Yes, we are dealing with a really grave danger.

Hackers aren’t the first to make a move like this. Users are led to believe that the COM surrogate is a standard executable because of this deception. There are a lot of hackers out there who don’t want you to realize that executables might be infected with malware.

Separating Malicious executables from the Legitimate ones

It is impossible for us to locate the malicious exe files and the legit ones. But this can be done by scanning your computer with an anti-malware security scanner at the file’s location –

C:\Windows\System32. The Windows folder keeps all the data needed for the smooth functioning of the system. System 32 is the folder where the DLL files are located on your disk.

The Symptoms of a COM Surrogate virus presence

These are the possible symptoms that would be displayed by your computer if it contradicts a COM surrogate virus or malware. 

  • A number of COM surrogate applications may be running in the task manager. You never know what you’ll find.
  • The COM objects might use up a significant portion of your CPU’s resources. CPU memory is used by every type of malicious software.
  • System performance might be affected. It’s possible that the infection is causing the issue.
  • Programs that are currently running are crashing over and over. You may get a message that reads, “This program has stopped working” The virus may be to blame.

To remove the COM surrogate virus from your computer, one has to understand what the COM surrogate process is and what it does. 

How does the COM surrogate work?

The moniker “COM Surrogate” may have appeared in the task manager on your computer at some point. The dllhost.exe process is an essential feature of the Windows OS and runs as part of the dllhost.exe file. Windows 7, Windows 8, and Windows 10 are all the same in this regard.

Microsoft created this interface many years ago to attach and expand other processes on your system. Windows’ file explorer, for example, generates thumbnails for photos, folders, and videos using COM objects.

Thumbnail creation is under the watchful eye of this specific COM object. There is an issue with thumbnails if this COM object fails. When this process was paused too frequently, engineers came up with the COM surrogate process as a solution.

With the aid of this COM surrogate process, you may start another COM object. For example, File Explorer uses a COM surrogate process to produce thumbnails. Only the COM surrogate will be affected if this is crashed. As long as File Explorer is open, nothing will be lost.

Is the COM Surrogate process a Virus?

The COM Surrogate processes are just a part of the Operating System and not viruses. But they can be manipulated to be harnessed by malware. Most malware uses dllhost.exe to infiltrate and corrupt the system.

If you notice anything suspicious about these processes, like high CPU usage, There are chances that it is malware. You have to scan your computer with antivirus software. If you do not have one, this is your reminder to download an anti-virus and run a full scan, just to be safe.  

Can the COM surrogate be disabled?

No. The COM surrogate Windows process is an integral part of the OS. If this was disabled, a lot of COM objects might not function. These were created by one program to run another program. So even when you try to disable it through the task manager (Ctrl + Shift + Esc), you cannot do it.

It was attempted to disable it by selecting the active COM surrogate process and clicking on the End Task button in the task manager. But the COM surrogate process popped up again when the task manager opened it again. Therefore, it is proved that the OS doesn’t let you kill it, even if you want to. 

Note: This experiment resulted in the same outcome for Windows 7, Windows 8, and also Windows 10.
