UnrealCEFSubprocess 1024x411

If UnrealCEFSubProcess is located in a subfolder of the Windows temporary files folder, the security assessment is 100% unsafe. The program does not have a window through which it can be viewed. Some malicious programs masquerade as UnrealCEFSubProcess.exe, especially when located in the C:\Windows or C:\Windows\System32 folder.

UnrealCEFSubprocess is an Adware-based product. It has been programmed to serve the marketing industry via efficiently promoting goods and services. This happens by making your browser distribute a big number of banner, pop-up, box and other online ads to your computer screen. No browser – neither Explorer, nor Chrome or Firefox could avoid producing ads, once your system has been infected with this piece of ad-generating software. Continue reading for more detailed explanations of the typical behavior and expected effects of UnrealCEFSubprocess once inside your system.

Possible negative effects

Although, we are not discussing a virus in this article, we must mention that UnrealCEFSubprocess could sometimes contribute to a worse system performance. This happens especially to machines with scarcely enough resources. The generation of many pop-ups and other diverse ads might slow down a computer with a smaller resource capacity. This is not that serious and can be fixed by closing down the produced advertisements. Another potential unpleasant effect of this Adware is that sometimes it can broadcast too many ads, which could completely cover your browser window and leave you unable to load any pages. Such a consequence might disturb you very much, but it cannot harm you of your PC.

 Please follow all the steps below in order to remove UnrealCEFSubprocess!

How to remove UnrealCEFSubprocess

  1. First, click the Start Menu on your Windows PC.
  2. Type Programs and Settings in the Start Menu, click the first item, and find UnrealCEFSubprocess in the programs list that would show up.
  3. Select UnrealCEFSubprocess from the list and click on Uninstall.
  4. Follow the steps in the removal wizard.

What we suggest you do first is, check the list of programs that are presently installed on the infected device and uninstall any rogue software that you find there:

  • From the Start Menu, navigate to Control Panel ->>> Programs and Features ->>> Uninstall a Program.
  • Next, carefully search for unfamiliar programs or programs that have been installed recently and could be related to UnrealCEFSubprocess.
  • If you find any of the programs suspicious then uninstall them if they turn out to be linked to UnrealCEFSubprocess.
  • If a notification appears on your screen when you try to uninstall a specific questionable program prompting you to just alter it or repair it, make sure you choose NO and complete the steps from the removal wizard.

Remove UnrealCEFSubprocess from Chrome

  1. Click on the three dots in the right upper corner
  2. Go to more tools
  3. Now select extensions
  4. Remove the UnrealCEFSubprocess extension
  • Once you open Chrome, click on the three-dots icon to open the browser’s menu, go to More Tools/ More Options, and then to Extensions.
  • Again, find the items on that page that could be linked to UnrealCEFSubprocess and/or that might be causing problems in the browser and delete them.
  • Afterwards, go to this folder: Computer > C: > Users > *Your User Account* > App Data > Local > Google > Chrome > User Data. In there, you will find a folder named Default – you should change its name to Backup Default and restart the PC.
  • Note that the App Data folder is normally hidden so you’d have to first make the hidden files and folders on your PC visible before you can access it.

How to get rid of UnrealCEFSubprocess on FF/Edge/etc.

  1. Open the browser and select the menu icon.
  2. From the menu, click on the Add-ons button.
  3. Look for the UnrealCEFSubprocess extension
  4. Get rid of UnrealCEFSubprocess by removing it from extensions

If using Firefox:

  • Open Firefox
  • Select the three parallel lines menu and go to Add-ons.
  • Find the unwanted add-on and delete it from the browser – if there is more than one unwanted extension, remove all of them.
  • Go to the browser menu again, select Options, and then click on Home from the sidebar to the left.
  • Check the current addresses for the browser’s homepage and new-tab page and change them if they are currently set to address(es) you don’t know or trust.

If using MS Edge/IE:

  • Start Edge
  • Select the browser menu and go to Extensions.
  • Find and uninstall any Edge extensions that look undesirable and unwanted.
  • Select Settings from the browser menu and click on Appearance.
  • Check the new-tab page address of the browser and if it has been modified by “UnrealCEFSubprocess” or another unwanted app, change it to an address that you’d want to be the browser’s new-tab page.

How to Delete UnrealCEFSubprocess

  1. Open task manager
  2. Look for the UnrealCEFSubprocess process
  3. Select it and click on End task
  4. Open the file location to delete UnrealCEFSubprocess
  • Access the Task Manager by pressing together the Ctrl + Alt + Del keys and then selecting Task Manager.
  • Open Processes and there try to find a process with the name of the unwanted software. If you find it, select it with the right button of the mouse and click on the Open File Location option.
  • If you don’t see a “UnrealCEFSubprocess” process in the Task Manager, look for another suspicious process with an unusual name. It is likely that the unwanted process would be using lots of RAM and CPU so pay attention to the number of resources each process is using.
  • Tip: If you think you have singled out the unwanted process but are not sure, it’s always a good idea to search for information about it on the Internet – this should give you a general idea if the process is a legitimate one from a regular program or from your OS or if it is indeed likely linked to the adware.
  • If you find another suspicious process, open its File Location too.
  • Once in the File Location folder for the suspicious process, start testing all of the files that are stored there by dragging them to our free online scanner available below.
  • Each file will be scanned with up to 64 antivirus programs to ensure maximum accuracy

    Are Adware-based programs viruses? How about UnrealCEFSubprocess?

    So far we have no proof that Adware-type programs could be classified as malicious. Truly, they might be very irritating and even sometimes intrusive, but no malicious activities are typical for them. So UnrealCEFSubprocess not a “Virus”. Adware does NOT lead to file encryption or system crashes. Its effects have never involved blackmailing you, corrupting your system or some of your data or destroying anything you possess. Nor have they involved personal information theft or espionage, which are characteristics of real malware like Trojans and Ransomware. The only considerably intrusive activity that is characteristic of programs like UnrealCEFSubprocess is the research they may conduct revolving around the interests and personal preferences of the affected users. When it comes to ad-producing software, this research may involve carefully scrutinizing your browser history. The results are comprised of the webpages you visit and products you usually review or search for online. Then the generated ads include only such or similar webpages, software and goods. Some users could feel that this activity is an act of invading their privacy. Apart from that, nothing is considered suspicious when it comes to Adware.

    Is UnrealCEFSubprocess dangerous?

    All known ad-producing software, including Adware and browser hijackers, could be found in various places. The distribution methods such programs exploit are very diverse – from torrents to drive-by downloads; from infected websites to spam. So far the biggest number of infections is still caused by installing a software bundle. Please note that bundles are rarely dangerous. They represent sets of apps, programs, sometimes games, that are available online, usually for free. There could be many useful programs inside them that might be very helpful or necessary for your system, but there might also be browser hijackers and Adware. Simply downloading such a software mix won’t leave your PC contaminated, however, improperly installing the program bundle surely will. To stay away from any ad-broadcasting program, you have to learn how to opt out of any and all of them. For that purpose, you should use the installation feature that will allow you to do that. Such options are the Advanced and the Custom ones – do not think twice, choose only them. When you do so, you will be shown a full detailed list of the contents of the bundle during the installation process and you will be able to remove all the potentially unwanted programs from that list.
