This is a genuine process of Windows 10 and is designed particularly to run extensions for different programs. However, many users think that this is a virus, well that is not true.

The process COM Surrogate points out that your computer is running many software extensions at the same time. These extensions are known as COM Objects. The regular users may not be able to detect this process because it has no icon and the name is also not very common. Due to this, normal users think that their system is infected.

Windows 8– Here also you have to start Windows 8 in the Safe Mode. Open the Start screen and in the search bar, you have to write “Advanced”. Select the option of “Advanced startup”. From here, you have to click on the button of “Restart now”. Now, your computer will start up in the “Advanced Startup options menu”. From this list, you have to select the option of “Troubleshoot”. Then, click on the button of “Advanced options”. After that, you have to select the “Startup Settings” option. From here, you have to press the button of “Restart”.

Step. IV

Open the application of Autoruns and click on “Options”. This will be located at the top of the page. Here, you have to uncheck the box of “Hide Windows Entries” and “Hide Empty Locations”. Then, press the icon of “Refresh”.  

Step. V

Now, go through the list provided by Autoruns and find the malware that you want to delete. Any COM application that is not running the dllhost.exe COM Surrogate application is malware. You must write down the path for this malware. You must know that some malware disguises their name after some legitimate process name of Windows. After finding the malware, right-click on it and select the option of “Delete”. Be extra cautious that you do not delete any system files.

After deleting the malware, you must search your computer for the same malware. This will ensure that there are no more of the malware present on your computer. You must first enable the “hidden files and folders”. Be sure to remove any remaining files of the malware if you find any. Now, restart your computer in “Normal Mode”. 


By following the above steps, you will be able to remove the malware from your system. If you see a COM process that is not running the dllhost.exe COM Surrogate application, then that means it is a malware. However, this manual process of removing the malware is for skilled computer users. A normal user will not be able to effectively implement the process. Moreover, if you are infected with advanced malware, this process might not work.

To keep your computer safe, you can download a robust anti-malware software. It is always better to protect your computer from threats rather than fixing the problem later. COM Surrogate in itself is not a virus. This is a genuine Windows process.
