What is COM Surrogate?
COM Surrogate is a genuine Windows 10 process that is designed to run various program extensions. Users are more or less certain to find this process in Windows Task Manager.
Therefore, the presence of this process does not mean that the system is infected, however, some viruses are developed to disguise themselves using COM Surrogate process names to prevent detection.
The COM Surrogate process name indicates that the system is running various software (e.g., Internet Explorer) extensions. These extensions are called COM Objects, hence the use of the COM Surrogate name. This process title may not be obvious to regular users, since it has no icon and the name seems rather unusual. Therefore, users often believe that the system is infected and that this process is malicious.
In most cases, however, it is not. Be aware that the genuine COM Surrogate process runs a dllhost.exe application, which is placed in the "\Windows\System32" folder. If, however, you have checked COM Surrogate's properties and noticed that it is running another application, your system is probably infected. High-risk viruses often hide behind the names of legitimate system processes to avoid detection.
Furthermore, the genuine COM Surrogate process uses few computer resources (it barely uses any CPU and takes just a few megabytes of RAM). Therefore, high resource use can also indicate a computer infection.
If you have noticed a COM Surrogate process using many resources and running an application other than dllhost.exe from the "\Windows\System32" directory, scan the system with a reputable anti-virus/anti-spyware suite and delete all detected threats immediately.
Most malware infections that disguise themselves as genuine Windows processes are trojans (which collect sensitive data, open back doors, allow criminals to remotely manipulate the system, etc.) and ransomware (which encrypts data, locks the computer screen, etc.).
The presence of these programs might lead to serious privacy issues, significant financial/data loss, and further system infections.

|Symptoms||Trojans are designed to stealthily infiltrate the victim's computer and remain silent. Thus, no particular symptoms are clearly visible on an infected machine.|
|Distribution methods||Infected email attachments, malicious online advertisements, social engineering, software cracks.|
|Additional Information||COM Surrogate is a genuine Windows 10 process, however, some trojans hide behind this name to avoid detection. The genuine COM Surrogate process runs the dllhost.exe application, which is placed in the \Windows\System32 folder and barely uses any computer resources. Fake COM Surrogate processes are easily distinguishable, since they run apps placed elsewhere and often extensive resources.|
|Damage||Stolen banking information, passwords, identity theft, victim's computer added to a botnet, financial/data losses, decreased computer performance.|
|Malware Removal (Windows)||
To eliminate possible malware infections, scan your computer with legitimate antivirus software. Our security researchers recommend using Combo Cleaner.
The behavior of these infections can differ (e.g., stealing account credentials, connecting infected computer to a botnet, allowing cyber criminals to control the system remotely, encrypting data to make ransom demands, and so on), however, all of these viruses pose a significant threat to your privacy and computer safety. Therefore, you should eliminate these threats immediately.
How did COM Surrogate infiltrate my computer?
Trojans and ransomware are typically proliferated using spam email campaigns, third party software download sources, other trojans, and fake software updaters/cracks.
Spam campaigns are used to send hundreds of thousands of emails that contain deceptive messages encouraging users to open malicious attachments (which are usually presented as invoices, bills, receipts, or other "important documents"). Opening them leads to a computer infection. Unofficial download sources present malicious executables as legitimate software.
Users are tricked into downloading and installing malware manually. Some trojans cause so-called "chain infections". They infiltrate computers and continually install additional malware. Fake updaters infect computers by exploiting outdated software bugs/flaws or simply downloading and installing malware rather than updates.
Cracks work in an identical manner. They allow users to bypass paid software activation free of charge, however, criminals often use them to proliferate malware, and thus users typically end up infecting their computers rather than gaining access to paid features.
How to avoid installation of malware?
The main reasons for computer infections are poor knowledge and careless behavior. The key to safety is caution. Therefore, to prevent computer infections, be very cautious when browsing the internet and downloading, installing, and updating software. If you receive an email from a suspicious address or the attached link/file seems suspicious or irrelevant, do not open anything.
Download apps from official sources only, using direct download links. Third party downloaders/installers often include rogue apps, and thus these tools should never be used. Keep installed applications and operating systems up-to-date. To achieve this, use only implemented functions or tools provided by the official developer.
Never attempt to crack installed applications, since software piracy is a cyber crime and the risk of infections is extremely high.
Have a reputable anti-virus/anti-spyware suite installed and running as these tools detect and eliminate malware before the system is harmed. If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

Manual malware removal is a complicated task - usually it is best to allow antivirus or anti-malware programs to do this automatically.
To remove this malware we recommend using Combo Cleaner Antivirus for Windows. If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:
If you checked the list of programs running on your computer, for example, using task manager, and identified a program that looks suspicious, you should continue with these steps:
Download a program called Autoruns. This program shows auto-start applications, Registry, and file system locations:
Restart your computer into Safe Mode:
Windows XP and Windows 7 users: Start your computer in Safe Mode. Click Start, click Shut Down, click Restart, click OK. During your computer start process, press the F8 key on your keyboard multiple times until you see the Windows Advanced Option menu, and then select Safe Mode with Networking from the list.

Extract the downloaded archive and run the Autoruns.exe file.
In the Autoruns application, click "Options" at the top and uncheck the "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.
Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.
You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".
After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.
Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs.
These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.
To be sure your computer is free of malware infections, we recommend scanning it with Combo Cleaner Antivirus for Windows.
