There are hundreds of background operations that keep Windows running on a day to day basis. However, the end-user doesn’t necessarily know about all of them.

Seeing an unusual process eat up all your RAM isn’t a new thing for Windows. However, you should know whether or not it’s a legitimate Windows process or malware under disguise.

In this article, we’re talking about the cefsharp.browsersubprocess.exe, whether it’s a legitimate process, and should you get rid of it immediately.

What is cefsharp.browsersubprocess.exe?

The process generally refers to a browser sub-processor or, in simpler words, it is most likely an extension. However, if it’s using too much memory, it might as well be malware.

To confirm its identity, try verifying the process’ signer. If the signature is verified, you have nothing to worry about. However, if it isn’t, you might have a problem on your hands that requires immediate action. 

Should you delete this process?

Under normal circumstances, the process will occasionally spike in usage and will stay relatively quiet most of the time. However, if it’s frequently using way too many resources, you can shut the process down. Not to mention if you discover it’s malware in disguise, you should stop the process and delete all associated files.

Step 1: Right-click the taskbar and click on Task Manager.

Step 2: Find the process, right-click it and select Open file location.

Step 3: Now head back to the Task Manager and kill the process using the End Task button in the bottom right. Alternatively, you can also right-click the process and select End Task.

Step 4: Now, remove all files associated with the process.

Restart your PC and monitor resource usage again. It should be lower than before and if the process pops up again, try scanning your PC for any malware or viruses you might’ve gotten your machine infected with.
