cefsharp.browsersubprocess.exe | Is It Safe? | How To Fix?

The cefsharp.browsersubprocess.exe executable file allows a developer to embed the Chromium web browser into C# or VB.Net programs using the Chromium Executable Framework (CEF).

It is usually safe, but can be used by hackers to mask malware and so many users would elect to remove it from their PC. We investigate.


Chromium, CEF and CEFSharp

What Is Chromium?

chromium

Chromium is an Google run open-source browser project. It’s similar to Google’s Chrome browser, but available to other software developers to use.

Microsoft Edge, for example, uses Chromium.

CEF

The Chromium Embedded Framework (CEF) is a separate open-source project. It enables applications such as Adobe Acrobat, Minecraft and MATLAB to use this browser.

What Is CEFSharp?

Is cefsharp.browsersubprocess.exe Safe?

The Chromium Embedded Framework – and related CEFSharp – is a reputable project. A significant number of major companies, and hence applications, use it.

The related cefsharp.browsersubprocess.exe file should, therefore, be safe.

Is It A Virus?

Hackers can mask viruses by using similarly named files.

One way to check whether such a file is virus is to check the exe file’s location. Malware such as viruses and trojans – with a similar name – are often in a unusual folder.

Hence a good indicator of a file’s providence is its location.

Here’s how to check the file’s location:

a. Press ctrl-alt-del
b. Click on the ‘Details Tab’. Examine cefsharp.browsersubprocess.exe
c. Highlight the cefsharp.browsersubprocess.exe file
d. Right click and click ‘Properties’ to get the following screen:

If the location is C:\\Windows\System32, the test is passed.

  • There was a problem starting cefsharp.browsersubprocess.exe
  • cefsharp.browsersubprocess.exe Could Not Be Found

These errors are caused by:

  • An out of date file
  • Applications loaded on an old machine
  • Too many programs opened on a PC

It is common the find the file in Task Manager too, which often causes concern.


How To Fix cefsharp.browsersubprocess.exe and Chromium Embedded Framework Errors
