In Windows 10: What is COM Surrogate & Is It a Virus or Not?

COM Surrogate

Do you know what is the COM Surrogate process in the Windows 10 task manager or have you ever noticed it? When I was browsing via the list of procedures and noticed at that time I saw two of them running on my system.

However, understanding the different methods in task manager can be quite a challenge. So I explain a post on svchost.exe in detail, which is a process that hosts different Windows services. There can easily and simply be 10 to 15 of these running on your system at any given period of time.

So in this post, we will look at what COM Surrogate is in Windows 10. Or whether you have to worry about it or not.

What is COM Surrogate?

COM Surrogate is the process where you really have no idea of what to do by looking at it. It does not have a custom icon and sits there without giving much information about what it functions.

Sometimes, multiple COM Surrogate processes running at a time. Similarly, if you go to the task manager, you will usually see two of them running.

Although if you right-click on either and select Go to Details, then you will view that the method name is literally dllhost.exe. So you will also notice that the process runs under your username and not the System or Local Service or Network Service accounts.

Fortunately, the COM Surrogate is basically not a virus (most of the time). It is just a legalized Windows 10 process that runs in the background. It is known as dllhost because this process is hosting DLL files. So that it may create no sense. So let’s explain it in further detail.

Primarily, Microsoft has made an interface for enhancers to make extensions to programs that are known as COM Objects. So this is used for certain programs in Windows 10 also. For instance, Windows Explorer contains a COM object that is able to permit it to create thumbnails for images and videos in a folder.

Although, the great issue with these COM objects was that they would crash and bring the Explorer process down with it too. So that meant your whole system would crash whether a COM object failed for any cause.

However, to fix this issue, Microsoft came up with the COM Surrogate method that fundamentally ran the COM object in a separate method than the one that appealed it. So, in the Explorer example, the COM object would not run in the explorer.exe procedure. Rather than in this recently created COM surrogate process.

Now, if the COM object is crashed, simply it would just take out the COM Surrogate method and the Explorer would continue running. Much smart.

Even if you install the Process Explorer, so at times you will able to view the COM object I am referring to above.

Whether you hang your mouse over the dllhost.exe entry, you will view the COM class is Microsoft Thumbnail Cache. That is the extension, use to make the thumbnails in Explorer.

COM Surrogate Can be a Virus or not?

Instances have been there that in the past where trojans and viruses have hidden in the Windows operating system. By masking themselves as COM Surrogate and also the other Windows methods.

Similarly, if you go to the task manager, so then you have to right-click on the procedure. Then select Open file location, now you will be able to find the source location for the process.

Furthermore, if the COM Surrogate process is leading to a file called ‘dllhost’ in the C:\Windows\System32 folder. So it is then unlikely to be a virus. Similarly, if it leads elsewhere, you should run a virus scan promptly.

Normally, the COM surrogate uses very little memory and CPU. Also, there are only one or two instances of it running. If various dllhosts.exe processes are there or the procedure is eating up more than 1 to 2 percent of your CPU. So here I would recommend performing an offline virus scan. That is able to better examine the tricky hidden viruses.

Hopefully, reading this article taught you a thing or two about COM Surrogate and Windows 10 background processes. So going forward, you should be less worried about viewing processes like this running in the background.
