What is cefsharp.browsersubprocess.exe?

Cefsharp.browsersubprocess.exe is a legitimate executable file associated with the Chromium Embedded Framework (CEF). CEF is an open-source framework that allows developers to embed a web browser control based on the Chromium browser engine into their applications. This enables developers to create applications with web browsing capabilities.

The cefsharp.browsersubprocess.exe process is responsible for rendering web content within applications that utilize the CEF framework. It acts as a separate subprocess to handle the web rendering tasks, ensuring that the main application remains responsive and stable.

Is cefsharp.browsersubprocess.exe a Virus or Malware?

While cefsharp.browsersubprocess.exe is a legitimate file, it is worth noting that malware or viruses can sometimes disguise themselves by using similar names. Therefore, it is essential to verify the location and digital signature of the file to ensure its authenticity.

If you suspect that cefsharp.browsersubprocess.exe on your system is malicious, it is recommended to scan your computer with reliable antivirus or anti-malware software. One such trusted tool is Malwarebytes Free, which can help detect and remove any potential threats.

Should I Remove cefsharp.browsersubprocess.exe?

However, if you notice any unusual behavior or suspect that the file may be compromised, it is advisable to investigate further. Here are a few steps you can take to ensure the integrity of cefsharp.browsersubprocess.exe:

  1. Verify the file location: The legitimate cefsharp.browsersubprocess.exe file is typically located in the installation directory of the application that uses the CEF framework. If you find the file in a different location, it may be a sign of malware.
  2. Check the digital signature: Right-click on the file, go to Properties, and navigate to the Digital Signatures tab. Verify the signature to ensure it is from a trusted source. If there is no digital signature or it is from an unknown publisher, it could indicate a potential threat.

Try updating the application that uses the CEF framework to the latest version, as newer releases often include bug fixes and performance improvements.
  • Crashes or freezes: If the cefsharp.browsersubprocess.exe process crashes or causes the application to freeze, it could be a result of incompatible browser extensions or corrupt cache files. Clearing the browser cache or disabling problematic extensions may help resolve the issue.

How to Stay Safe Online

Here are 10 basic security tips to help you avoid malware and protect your device:

  1. Use a good antivirus and keep it up-to-date.

    Shield Guide

    It's essential to use a good quality antivirus and keep it up-to-date to stay ahead of the latest cyber threats. We are huge fans of Malwarebytes Premium and use it on all of our devices, including Windows and Mac computers as well as our mobile devices. Malwarebytes sits beside your traditional antivirus, filling in any gaps in its defenses, and providing extra protection against sneakier security threats.

  2. Keep software and operating systems up-to-date.

    updates-guide

    Keep your operating system and apps up to date. Whenever an update is released for your device, download and install it right away. These updates often include security fixes, vulnerability patches, and other necessary maintenance.

  3. Be careful when installing programs and apps.

    install guide

    Pay close attention to installation screens and license agreements when installing software. Custom or advanced installation options will often disclose any third-party software that is also being installed. Take great care in every stage of the process and make sure you know what it is you're agreeing to before you click "Next."

  4. Install an ad blocker.

    Ad Blocker

    Use a browser-based content blocker, like AdGuard. Content blockers help stop malicious ads, Trojans, phishing, and other undesirable content that an antivirus product alone may not stop.

  5. Be careful what you download.

    Trojan Horse

    A top goal of cybercriminals is to trick you into downloading malware—programs or apps that carry malware or try to steal information. This malware can be disguised as an app: anything from a popular game to something that checks traffic or the weather.

  6. Be alert for people trying to trick you.

    warning sign

    Whether it's your email, phone, messenger, or other applications, always be alert and on guard for someone trying to trick you into clicking on links or replying to messages. Remember that it's easy to spoof phone numbers, so a familiar name or number doesn't make messages more trustworthy.

  7. Back up your data.

    backup sign

    Back up your data frequently and check that your backup data can be restored. You can do this manually on an external HDD/USB stick, or automatically using backup software. This is also the best way to counter ransomware. Never connect the backup drive to a computer if you suspect that the computer is infected with malware.

  8. Choose strong passwords.

    lock sign

    Use strong and unique passwords for each of your accounts. Avoid using personal information or easily guessable words in your passwords. Enable two-factor authentication (2FA) on your accounts whenever possible.

  9. Be careful where you click.

    cursor sign

    Be cautious when clicking on links or downloading attachments from unknown sources. These could potentially contain malware or phishing scams.

  10. Don't use pirated software.

    Shady Guide

    Avoid using Peer-to-Peer (P2P) file-sharing programs, keygens, cracks, and other pirated software that can often compromise your data, privacy, or both.

To avoid potential dangers on the internet, it's important to follow these 10 basic safety rules. By doing so, you can protect yourself from many of the unpleasant surprises that can arise when using the web.
