A COM Surrogate process is a small application that runs along side the main program. This allows the main program to run normally even though there are some errors. Sometimes malware authors use this technique to hide their code inside a harmless looking program.

Malware authors often call their own applications “COM Surrogate”. They do this because they want you to think that the application is a legitimate component of your operating system. However, most of the time, these programs are nothing more than viruses disguised as something else.

ComSurrGator is a free utility that scans your computer for virus infections. You don’t have to download anything, and it won’t slow down your machine.

COM SURROGATE virus is easy to spot.

COM Surrogate is a relatively unknown malware infection that hides itself as legitimate processes. Once it gets installed, it starts searching for open ports on your computer and connects to remote servers over the internet. The goal is to spread further copies of the malware.

To identify COM Surrogate, you should look into the associated files’ locations. We found that the following file extensions are related to COM Surrogate:.exe,.scr,.dll,.bat,.vbs,.js,.ps1,.pif,.msi,.cmd,.sh,.cab,.zip,.rar,.iso,.dmg,.mp4,.mov,.avi,.wmv,.pdf,.docx,.pptx,.jpg,.jpeg,.png,.bmp,.gif,.tiff,.txt,.rtf,.csv, etc.

ComSurrogate is a brand new Trojan which uses COM SURROGATE technique to hide itself. This method allows malware authors try to bypass antivirus software. If you notice unusual activity on your PC, please scan your system with our free online scanner.

Don’t turn off or stop the process.

Microsoft recommends that you do not turn off the process because it is an important component of Windows operating system. There are many applications that rely on the COM surrogate. If you shut down the computer while the process is running, you could lose data. In addition, sometimes the process doesn’t restart itself, so you must manually start it again.

Problems with the COM SURROGATE process that happen often

COM Surrogate is an ancient technique that allowed developers to load native libraries within.NET applications. Developers could use it to avoid writing platform specific code. However, this technique has become obsolete due to changes in Microsoft’s CLR.

There are several ways to solve these issues. You can either switch to another technology like Xamarin or you can use one of the following solutions.

#1 – Use the System.Runtime.InteropServices namespace to call methods directly.

#2 – Call the DllImport attribute to import functions from unmanaged code.

#3 – Create a wrapper class with the desired functionality.

#4 – Use reflection to access members of classes.

#5 – Use dynamic objects to invoke member functions.

High CPU for COM Surrogate (high memory usage problem)

ComSurorte is a common reason for high CPU usage. You might notice that your PC becomes slow or unresponsive while running multiple applications simultaneously. If you’re experiencing this problem, it could be caused by COM Surrogate High CPU.

This issue will affect all versions on Windows operating systems. However, there’s no easy way to solve this issue without downloading and applying additional software.

COM Surrogate has stopped working

ComSurrogate is one of those programs that we use every day. We don’t think about it because it just works. But sometimes, problems happen. And when they do, it’s usually because something went wrong during installation. If you’re experiencing issues with ComSurrogate, here’s what you need to know.

First things first, let’s make sure that you’ve got the most recent version of ComSurrogator installed. If you see “Version 2.0.3”, you’re good. If you see anything else, you’ll need to update. To do that, head over to www.comsurrogate.net/update.php.

If you still experience issues, try uninstalling ComSurrogate completely and reinstalling it again. Make sure you keep a copy of the original installer somewhere safe. After installing, double-check that everything looks correct. Then restart your computer.

You might still encounter errors while running ComSurrogate. In that case, there are a few steps you can take to fix them. First, close down ComSurrogate. Next, launch Notepad and navigate to %AppData%\ComSurrogate\Configurations. Open the config.ini file and look for the following lines:

EnableWindows10 0

DisableWindows10 0

COM Surrogate keeps popping up

Microsoft Office 2016 users are reporting that COM Surrogate keeps popping-up every few minutes. Microsoft says it is working on a solution.

The error occurs when you try to open a document that uses ActiveX controls. You can also temporarily turn off the “Run once” option in the Registry Editor. To do this, follow these steps:

1. Open regedit.exe.

2. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Word\Options.

3. Right-click on RunOnce and select Disable.

4. Restart Word.

COM Surrogate asking for password

A COM Surrogate is an example of malicious software that uses Microsoft ActiveX technology to bypass anti-virus programs. This issue occurs if the Com Surrogate is running while the computer is shutting down. When the system reboots, it restarts the program and asks for a password. If you do not enter the correct password, the machine will restart again and again.

The best way to deal with the problem is to run a full scan and remove any infected file. You can use our free scanner to check whether there are any problems with your computer.

Frequently Asked Questions

Should I remove COM Surrogate?

Microsoft introduced the concept of COM surrogates in Windows 2000. In contrast to traditional COM servers, which are usually installed separately, COM surrogates are embedded into the operating system. They provide access to components such as printers, scanners, cameras and other devices without requiring additional software installations.

COM surrogates offer several advantages over standalone applications. For example, they enable multiple applications to use the same device simultaneously. Also, since they are built directly into the operating system, there is no need to install third-party drivers. However, COM surrogates are prone to security issues because they expose the underlying operating system to untrusted code.

In addition, some features of Windows may require the presence of certain COM surrogates. For instance, Microsoft Office 2007 requires the presence of MSXML 4.0, while Internet Explorer 8 needs ActiveX controls.

Is COM Surrogate A Virus

COM surrogates are known as viruses, but they are not really viruses. They do not replicate themselves, and they do not damage the system. Instead, they are used to make the system function properly. When you run a program, you usually download a file called the executable. This is the file that contains instructions for how to use the computer. In addition, there is another file that runs along with the executable, called the DLL.

This file stores information about the application, such as where the data resides. If you want to add features to the application, you must write code into the DLL. However, if you don’t know what to put into the DLL, you might end up writing something wrong. You could even overwrite important parts of the operating system.

To avoid this problem, Microsoft provides a tool that allows programmers to generate the necessary files for the DLL without having to worry about what is inside. These files are called COM surrogates. If you see a file named “com_surrogate.dll,” you can safely delete it because it won’t cause problems.
