COM Surrogates are processes that run a COM object outside its main process. They can cause problems because they consume resources such as memory or disk space. You can use the Registry Editor to disable them temporarily. This windowsbulletin article explains how to fix COM Surrogate high CPU or disk usage in windows 10.

What is a COM Surrogate?

COM surrogates are an integral part of the Windows operating system. These are small programs that help Windows run smoothly. You can think of it as a translator – it translates the code written in one language into another. For example, let’s say you want to use a particular program called “MyApp”. If MyApp doesn’t support Windows 10, you won’t be able to download it. In such cases, a COM surrogate helps the app work on Windows 10.

COM surrogates are used to host DLL files. A DLL file contains executable instructions that perform specific tasks. Without a DLL file, Windows wouldn’t know how to execute those instructions. So, whenever you install a new application, you might see a file named “dllhost.exe”. That’s because the installer needs a COM surrogate to load the DLL file.

Is COM Surrogate a Virus?

COM surrogates are not viruses; however, they can cause damage to a computer if they are designed in such a way that it looks like a virus. They can come in different forms, including modifying registry settings or creating an executable file.

There are many ways to create COM surrogates, including modifying registry settings and creating an executable file. These methods include modifying the registry settings, adding a.reg file, or renaming the original file and placing it into a folder where it is executed automatically.

When a COM surrogate is detected by the operating system, Windows displays a warning message and asks whether you want to remove it. If you choose to delete the file, you will lose access to some functions of the program. However, there is no harm done to your computer unless you allow the program to run without being checked.

Why does the problem occur?

Ransomware is one of the biggest threats to our personal data today. It has been around since the early 2000s, but it has become much more prevalent over the past few years. In fact, there are now thousands of variants of ransomware out there, each targeting a specific type of device or operating system. While we don’t know exactly how many people are affected by ransomware, experts estimate that it costs businesses $1 billion every month due to lost productivity and downtime.

The good news is that there are several things you can do to protect yourself against ransomware. Here are some of the most important ones.

Keep your operating system up to date: One of the best ways to prevent a ransomware attack is to keep your operating system up to date. This includes keeping your antivirus software updated, installing patches for known vulnerabilities, and making sure your apps are running the latest version of the software. If you’re worried about privacy, make sure your browsers are set to use HTTPS connections whenever possible.

Back up your data regularly: If you’ve ever had your computer crash, you know how devastating losing everything can be. Unfortunately, ransomware doesn’t discriminate; it’ll encrypt just about anything on your hard disk. So, even though it might seem like a hassle to backup your files regularly, doing so could save you a lot of trouble later. You can use cloud storage solutions like Dropbox, OneDrive, Box, Gdrive, etc., to easily store copies of your documents online. Or, you can simply copy files to external drives or USB sticks. Either way, backing up your data regularly helps ensure that you won’t lose everything if something goes wrong.

Use strong passwords: A strong password is one of the easiest ways to avoid getting locked out of your own computer. The longer the password, the better, as long passwords tend to be harder to crack than short ones. But, don’t go overboard with your password strength. A good rule of thumb is to have at least eight characters (including numbers, letters, and special symbols) and mix upper-case and lower-case letters in different combinations. Also, try not to repeat any words or phrases within your password.

Don’t click on links from untrusted sources: While this may sound obvious, clicking on links from untrusted sources can lead to malware infections. That’s why it’s always a good idea to check the URL before opening a link. For example, if you see an email address ending in, chances are it came from someone who wants to scam you. Instead, look for addresses ending,.net, These are all legitimate websites.

Install antivirus software: Antivirus software is another great way to help protect your PC from ransomware attacks. There are two main types: signature-based and heuristic-based. Signature-based programs scan your entire drive looking for malicious code. They then compare what they find to a database of known viruses. Heuristic-based programs work differently. Rather than scanning your entire drive, these programs only scan files when they open them. As soon as they detect a virus, they delete it automatically. Both types of antivirus software are effective against most ransomware threats. However, some ransomware variants can bypass both types of protection. In those cases, you should consider using a third-party program.

Launch the SFC scanning


The System File Checker scans your computer for missing or corrupt system files. It also checks whether there are problems with the registry.

  1. Type sfc /scannow into the search box. Click OK.
  2. If the Scanning progress bar appears, wait until it finishes. When it does, click Finish.
  3. Restart your computer after executing the scanning process.

The scanlog.txt file contains information about what files are infected and where they are located on your hard disk. This log file can be used to determine whether you want to delete the virus.

Frequently Asked Questions

The Component Object Model (COM), or simply COM, is a standard way for applications written in different programming languages to interact. This method is used to build software components that work together. For example, you might use it to make sure that a photo editing program doesn't crash while saving images. You could also use it to connect to databases and retrieve information.

COM works well because it creates a sort of bridge between two separate programs. However, it does come with some drawbacks. One of those problems occurs when one component fails, causing the entire system to stop working. In the case of Windows, it happens when a single COM object fails. When that happens, the whole operating system stops functioning properly.

COM Surrogate is a feature of Windows 10 that allows applications to access shared memory across processes. Applications use it to communicate with each other, but you don’t want to turn it off because it’s essential to running some programs.

The COM Surrogate virus doesn't do anything harmful itself, but it does spread throughout your computer system. Once installed, it starts looking for other viruses like Trojans, worms, spyware, etc. that might be lurking around. When it finds those things, it downloads them too.

If you're infected with the COM Surrogate, there are three easy steps you can take to clean up the mess.

  • Run a computer scan.
  • Use a third-party antivirus.
  • Reboot your computer.
