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

How to remove Cerobgar

  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 Cerobgar in the programs list that would show up.
  3. Select Cerobgar 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 Cerobgar.
  • If you find any of the programs suspicious then uninstall them if they turn out to be linked to Cerobgar.
  • 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 Cerobgar 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 Cerobgar 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 Cerobgar 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 Cerobgar 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 Cerobgar extension
  4. Get rid of Cerobgar 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 “Cerobgar” or another unwanted app, change it to an address that you’d want to be the browser’s new-tab page.

How to Delete Cerobgar

  1. Open task manager
  2. Look for the Cerobgar process
  3. Select it and click on End task
  4. Open the file location to delete Cerobgar
  • 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 “Cerobgar” 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

    • If the scanner finds malware in any of the files, return to the Processes tab in the Task Manager, select the suspected process, and then select the End Process option to quit it.
    • Go back to the folder where the files of that process are located and delete all of the files that you are allowed to delete. If all files get deleted normally, exit the folder and delete that folder too. If one or more of the files showed an error message when you tried to delete them, leave them for now and return to try to delete them again once you’ve completed the rest of the guide.

    2. Search for Startup Apps
    3. Look for Cerobgar in there
    4. Uninstall Cerobgar from Startup Apps by turning it off
    • Now you need to carefully search for and uninstall any Cerobgar. racing-related entries from the Registry. The easiest way to do this is to open the Registry Editor app (type Regedit in the windows search field and press Enter) and then open a Find dialog (CTRL+F key combination) where you have to type the name of the threat. 
    • Perform a search by clicking on the Find Next button and delete any detected results. Do this as many times as needed until no more results are found. 
    • After that, to ensure that there are no remaining entries lined to Cerobgar in the Registry, go manually to the following directories and delete them:
    • HKEY_CURRENT_USER/Software/Random Directory. 
    • HKEY_CURRENT_USER/Software/Microsoft/Windows/CurrentVersion/Run/Random
    • HKEY_CURRENT_USER/Software/Microsoft/Internet Explorer/Main/Random

    What is Cerobgar?

    Cerobgar may be employed as an espionage tool, and used to gather sensitive info about you such as credit and debit card numbers, online passwords, personal conversations, and more. This info could then be used to blackmail you, to harass you, or to secretly drain your banking accounts without your knowledge.
    Another possible use of Cerobgar is to take over your whole system and force the infected computer to carry out tasks beneficial to the hackers. Such tasks could be cryptocurrency mining, DDOS attacks, spam e-mail distribution, etc. In such cases, it is likely that most, if not all of the CPU, and RAM of your machine would get used up to fulfill the Trojan’s task.
    Trojans such as Cerobgar may also be employed as backdoor tools, in which case the malware would be able to insert other dangerous threats inside your already infected computer. A common example of a malware category that gets distributed with the help of Trojans are the Ransomware cryptoviruses – these infections oftentimes travel alongside Trojan horse.
    Those were only three examples out of the many possible ways in which a Trojan may cause harm.

    Is Cerbogar dangerous?

    Techniques commonly used to spread Trojans like Cerbogar and Brontok include the use of spam messages, misleading ads from sketchy sites, fake request for software updates, and more. A very commonly encountered technique of Trojan horse distribution is the use of pirated content. Since many users go to illegal sites that distribute pirated software, and due to the lack of serious control on such sites, many hackers upload their Trojans there, disguising them as the installers of popular games and programs, or as the files of movies and other media.
    Once the malicious file is downloaded and executed on the user’s computer, the Trojan is released and is now free to carry out its nefarious task. In many cases, there wouldn’t be any visible symptoms of the ongoing infection, and if the Trojan is a new one (like Cerobgar), even the antivirus program may fail to spot the offending malware. Hopefully, if you have noticed the Trojan on time, the guide below will allow you to eliminate it before any serious damage has been caused.
