What is com Surrogate (dllhost.exe)? How to Fix COM surrogate process Error

com surrogate

What is com surrogate? To load DLL files, this COM surrogate process dllhost.exe is required and is necessary for your PC. In this post, we’re going to investigate what Com Surrogate does on my PC-is it a COM surrogate virus? We’re going to start!

Suppose you guys are concerned about COM Surrogate, then you’re likely to find it in your task manager and fear that it could be a virus.
So, you should know it’s almost definitely not before you go and format your computer or replace any hardware. Even, you don’t want to
delete it in either case. Is com surrogate has stopped working?

(dllhost.exe) COM Surrogate

Ok, COM stands for Object Model of Components. That’s an interface introduced back in 1993 by Microsoft. “This allows developers to use some different programming languages to create “com surrogate process. These COM objects mainly plug into other apps and expand them as well.

So, as the Windows file manager manages COM artefacts when opening a folder, it produces thumbnail images of images and several other files. This COM object handles the generation of thumbnails by processing images, videos, and all other media. This makes it possible to expand File Explorer along with, for example, support for new video codecs.

This can lead to issues, however. Assume that a COM object crashes, and then its host process will be taken offline. Well, it was common at one point for these thumbnail-generating COM objects to strike. Plus, take with them the entire Windows Explorer operation.

The Com Proxy

Therefore, if you want to fix this type of problem, then the COM Surrogate dllhost.exe method was developed by Microsoft. Currently, this COM process executes a COM object outside of the original method that requested it. Suppose the COM object crashes, and then only the COM Surrogate process will be taken down, and the real host process will not crash as well. Windows Explorer (now known as File Explorer) begins the COM Surrogate process whenever thumbnail images are created. The COM object, which does the job, is hosted by this COM method. Assume the COM object crashes when only the com surrogate process dllhost.exe crashes, and the initial loop of File Explorer can continue to truck as well.

The COM Proxy is the code that I do not feel best about, as the standard Microsoft blog The Old New Thing sets it in other words, so I’m going to ask COM to host it another time. This way, if it crashes, then rather than my approach, it’s the COM sacrificial mechanism that hits.

COM Surrogate Is Hosting

No more information is provided to you by the regular Windows Task Manager. Well, the COM object or DLL file is also hosted by a COM Surrogate process. What is com surrogate dllhost.exe? If you want this detail, we suggest that you use the Microsoft Process Explorer tool. In Process Explorer, you can download and mouse-over a dllhost.exe process to find out which COM object or DLL file is hosted.

Is the surrogate COM a virus?

In the past, trojans and viruses were concealed by masking themselves as COM Proxy and all other Windows processes in the Windows operating system. Right-click and pick Open File Location when you open Task Manager. For this operation, you can find the source’s location.

Suppose the COM Surrogate method leads to a file in the C:\Windows\System32 folder called ‘DLLhost.’ It’s impossible to be a virus then. If it is seen anywhere, then you can immediately run a virus scan.

COM surrogate dllhost.exe also uses very little memory and CPU, and actually, only one or two instances of it are running. Suppose there are several procedures for dllhosts.exe, or more than 1 to 2 percent of your com surrogate process is consumed by the process. So, I would recommend that an offline virus scan be done, which can also detect tricky hidden viruses better.
