The Captcha Checkout virus will display pop up ads and viruses


CaptchaCheckout is a browser hijacker that is technically not dangerous. In some instances, however, CaptchaCheckout enormous number of advertisements, banners, pop-ups, blinking notifications, and search page-redirects to various sponsored websites can be seen as potentially unwanted.

Basically, this program is created to collect telemetry information from the users’ browsers. Based on this info, Captcha Checkout then shows various advertising messages that can come in different forms, sizes, and colors. The main idea is to get the users to click on them, as these clicks eventually translate intro profit for the browser hijacker’s developers.

The more advertisements that get displayed, and the more intrusive they are, the more difficult it is for the web users to remove or close them. This is how the well-known Pay-Per-Click method functions, and how it provides the creators of such hijacker apps (Uniq Data Captcha, Coding Captcha) with revenue. And this is the primary reason for developing such kinds of programs. Some users may not enjoy getting constantly harassed by an infinite stream of advertisements, however, and would rather have the programs responsible for them removed.

Can Captcha Checkout be harmful?

Do not panic if you detect higher CPU usage, sluggish system behavior, increased use of internet data, and a steady flow of unstoppable advertisements on your screen. These are all likely caused by the activity of Captcha Checkout in your system.

Many users may get frightened when starts to aggressively redirect them to different sites, and may mistakenly refer to it as a virus infection. But the reality is, this is the worst that could ever directly do to your system.

And, trust us, it’s far less problematic than a real malware infection the likes of Ransomware or a Trojan horse viruses. Not only will your system be severely compromised if such harmful programs infect it, but also you may not be able to access your files until you make a ransom payment to the attackers. Fortunately, this is not something that hijackers do. Pieces of software like Captcha Checkout are entirely focused on ad-generation, and are not intended to harm your machine.

Ways to remove Captcha Checkout

As we mentioned above, the developers of programs like Captcha Checkout earn revenue from the ads this software displays, so they want to make sure that their programs remain in the computer for as long as possible. Therefore, uninstalling the Browser Hijacker can be a bit challenging. That’s why you may need some basic understanding of how to handle such software, as well as a comprehensive guide on how to uninstall it, just like the one below. Make sure you follow it carefully because if you do not pay attention, you may accidentally delete some important system file or Registry key, causing corruption and instability in your computer. For this reason, it is recommend that you try using the Captcha Checkout removal tool for a safer removal, which will automatically detect and remove the browser hijacker without any risks, in case you aren’t a very experienced computer user.

Remove Captcha Checkout Virus

To remove Captcha Checkout, the first suggested method is to try to remove any undesirable components from your browsers.

  1. Go to the main browser on your computer, select its menu, and visit the Extensions settings.
  2. If there’s anything on the Extensions page that may have been added to the browser by Captcha Checkout, delete it.
  3. After that, delete the browsing data (cookies, caches, etc.) to make sure there’s nothing left from the hijacker in that browsers.
  4. Lastly, to remove Captcha Checkout and prevent it from returning, clean any other browsers that you may have in the same way.

If simply deleting the rogue add-ons and temporary data from your browsers didn’t remove Captcha Checkout from your PC, then it is very likely that the unwanted app has made some other changes in the system that you’d first need to revoke before Captcha Checkout goes away. Instructions that will help you with this can be found below.

Detailed Captcha Checkout Removal Guide Before you begin the guide, we suggest you turn off your Internet – this may prevent the hijacker from obstructing your attempts to uninstall it. We also advise you to open this page on another device and look at the guide from that device because you will need to restart your PC while going through the next steps.

Step 1

First, you should make sure that there aren’t any problematic or rogue programs on your PC that may be the cause behind the hijacker infection.

You can see what programs are on your PC by going to Control Panel > Uninstall a Program (you can access the Control Panel from the Start menu).

When you look at the list of program installs, look for anything that has been installed recently (right before the hijacker infected you). If there are any programs installed around that time which also seem unreliable or unfamiliar, you should probably uninstall them. To delete a given program, first click on it in the list, then select Uninstall from the top, and follow the steps that are in the uninstallation wizard that shows up.

Be careful not to allow the uninstaller to keep anything related to the potentially unwanted program on your computer. If you see an option to keep any personalized settings for the program after the uninstallation, choose not to use that option.


Step 2


Next, you must check the processes currently running on your PC and stop the ones that may be liked to Captcha Checkout. All currently running processes can be seen in the Task Manager’s Processes section. To go there, press Ctrl + Shift + Esc and then click on Processes.

It is unlikely that the hijacker’s process would have the same name (Captcha Checkout), so you must use your own judgement to determine which of the listed items could be from the rogue app. A possible red flag is if a given process is using significant amounts of RAM (virtual memory) or CPU (processing power) while seemingly not being related to any regular program that’s currently active on the computer. However, there are many system processes that could oftentimes be quite resource-intensive, so, if there’s a process that you suspect of being from the hijacker, we suggest first looking it up before you quit it. If the process in question is indeed rogue, it’s almost guaranteed that other users and/or IT experts would have reported that on security forums.

One other thing that could help you single out potentially rogue processes is to right-click on the ones you think may be unwanted, go to their File Locations, and scan all file stored there with a reliable scanner tool. Right below, you can find one such tool – you can use it for free on our site, directly from the current page, as it requires no installation.

    In case the scanner find harmful code within any of the files in the Location Folder of the suspected process, go ahead and quit the rogue process and after that delete its folder. If the folder or any of the files in it are not deletable at the moment, then delete what you can and return later, once you finish the guide, to delete the rest.

    Task Manager2

    Step 3 To stop Captcha Checkout from starting any more of its rogue processes, it’s strongly recommended entering Safe Mode and keeping your PC in it until the end of this guide and the removal of the hijacker.

    Step 4 Once the unwanted programs and processes have been taken care of, it is time to check some of your PC’s settings and revoke any changes made to them by Captcha Checkout. First, select the Start Menu, type this “ncpa.cpl” in its search bar, and open the first app that appears in the results. This should open a folder with different networks show in it – right-click the one that you normally use, and then click on Properties. Find in the list of items the one labelled Internet Protocol Version 4 click on it, and select the next Properties button shown in that window. On the following window, there are two options that need to be selected/enabled – those are Obtain an IP address automatically and Obtain DNS server address automatically. If those options aren’t already selected, select them, and then proceed to the Advanced settings. In the Advanced settings window, open the DNS section and delete all items that may be present in the list shown in that section. Lastly, click the OK button on every open window to save and apply the changes you’ve just made.


    Now use the Start menu again to search in it for “msconfig” and open the first item from the search results. The System Configuration window should appear on your screen – when it does, select Startup, see if there are any items listed in that tab that you do not recognize or that have an unknown manufacturer and uncheck their boxes after which select OK.


    Finally, open the Start Menu once more, copy this next line, and place it in its search bar: “notepad %windir%/system32/Drivers/etc/host“. Hit Enter to open the corresponding file (a file named Hosts) and once it appears in front of you, see if there are any IPs or other strange text written under “Localhost“. If you see that anything is written there, copy it and write us a comment in which you paste the copied text. It is likely that what’s below “Localhost” in your Hosts file is from the hijacker, but we must first verify this by having a look at the text. Once we see the comment you’ve written us, we will write a reply to it, telling you if you should delete the suspicious text from the Hosts file on your PC.


    Step 5 In this next step, you must be very careful when finding and deleting Captcha Checkout items. Only delete those items you are sure are from the hijacker and ask us about anything that you are uncertain about, because if you end up deleting the wrong thing, this may have severe consequences for your system. Firstly, start the Registry Editor by pressing together the Winkey and keys, then typing regedit in the newly-appeared window, and hitting Enter. You will most likely be required to confirm that you want to start the Registry Editor app and allow it to make changes on the computer – if this happens, click on Yes. Next, select the Edit menu from the top of the Registry Editor, click Find, and use the search box that appears to look for rogue Captcha Checkout items in the Registry. Delete what gets found, repeat the search, delete the next thing, and continue like that until no more Captcha Checkout items are getting found.

    After that you need to do is find the following three locations in the left panel of the Registry Editor and check them for suspicious items with questionable names. Obviously, there won’t be anything there with the Captcha Checkout name, but if you see an item named anything like “2389r2983th9e8dh928e3r289“, you should probably delete it.

    • HKEY_CURRENT_USER/Software/Random Directory
    • HKEY_CURRENT_USER/Software/Microsoft/Windows/CurrentVersion/Run
    • HKEY_CURRENT_USER/Software/Microsoft/Internet Explorer/Main

    Step 6 Before you are finished with this guide, it is suggested that you check each of your browsers one more time to make sure there’s nothing unwanted in any of them Start by right-clicking the icon of your main one, opening its Properties window, and selecting the Shortcut section. In there, you will see a text field labelled Target – in it, there should be nothing written after “.exe” and so, if there is anything after it, you must delete it and then click on OK. The next thing you must do is open the browser, click its menu (in most browsers the menu icon is in the top-right, in the Opera browser it is in the top-left), and select the Extensions/Add-ons option. If you are using the Google Chrome browser, you will see the Extensions option after you click on More Tools. When you get to the Extensions page, you already know what needs to be done, so look for anything questionable or unknown that may be linked to Captcha Checkout and delete it after first disabling it.


    The next thing you must do is go to Settings/Options from the browser menu and then find and click on the Privacy and Security settings section.


    Next, find an option labelled Clear browsing data or Choose what to clear (if you are using Microsoft Edge) and select it.


    Make sure that all the boxes in the next window are ticked except the one for your Passwords, and select Clear Data/Clear Now to delete the temporary browsing data, hopefully removing all that may be left from the hijacker in your browser.


    Finally, don’t forget about your other browsers – do everything you did in your main one with them too to make sure they are also clean.

    If you are still having problems with Captcha Checkout There could be many reasons why the manual steps shown here may not fully rid you of Captcha Checkout. One possible such reasons is the presence of a malicious program such as a Rootkit or a Trojan Horse that is hiding in your system and is enabling Captcha Checkout to evade your removal attempts. In such cases, your best options are to either take your machine to a specialist or to use a professional malware-removal tool to clean the system. The good thing about the second option is that it can save you lots of time because a reliable anti-malware tool should be able to quickly find all malware data and settings in the system and get rid of them. One such tool we strongly recommend has been linked throughout the current guide, so, if you are still struggling to delete Captcha Checkout, you may want to give it a go.

    What is Captcha Checkout?

    Captcha Checkout is a browser hijacker that targets Chrome, Edge, Firefox, and other browsers on Windows computers with the goal to use them as advertising platforms. Common Captcha Checkout symptoms are a replaced browser homepage or search engine, as well as automatic page redirects and aggressive push notifications. Most of the time, hijackers like this one manage to get into the browser in one of two ways. The first is through the help of program installers that also carry the hijacker as a bonus component that’s included in the installation by default. If the user doesn’t uncheck the hijacker clause during the installation of that other program, they’d get the unwanted software element added to their main browser. The second common distribution technique is by displaying a permission request disguised as a captcha or something similar. The user is tricked into selecting Allow in the request pop-up, and this grants the hijacker permission to operate within the browser.

    How dangerous is Captcha Checkout?

    Captcha Checkout is not very dangerous, but it is still seen as a security liability because its effects on the browser could result in vulnerabilities that more dangerous programs may exploit. What makes Captcha Checkout potentially dangerous is the questionable nature of the content it promotes. The purpose of hijacker apps, in general, and Captcha Checkout, in particular, is to advertise various kinds of content and to make money for its developers through its paid promotions. Showing ads and automatically page-redirecting you is, in and of itself, not a harmful activity, and it won’t damage your system. The problem comes from the content that you may get exposed to. Most hijackers would typically promote anything – from legitimate and popular sites to sketchy and potentially dangerous ones. If you end up getting an ad that links to the latter category of sites, you could obviously get your computer exposed to a diverse range of dangers, including Ransomware, Trojans, phishing forms, and more.

    How to remove Captcha Checkout?

    To remove Captcha Checkout, you can either try deleting the rogue app with a specialized anti-malware tool that can remove hijackers, or you could do it manually. If you decide to remove Captcha Checkout manually, you must be very thorough with the clean-up process. Step 1: Check the Programs and Features section of the Control Panel, see if there’s any suspicious/unfamiliar program there that may be linked to Captcha Checkout, and, if there is, uninstall it. Step 2: With the help of the Processes tab in the Task Manager, find any Captcha Checkout processes that may still be active and quit them. Step 3: Visit the Hosts file, the Registry Editor, the DNS settings of the network you usually use, and the Startup items tab in System Configuration, and delete any entries added to them by the hijacker. Step 4: Go to every browser in the system, delete from it any unknown extensions and extensions you think are from Captcha Checkout, and then clear the browser’s data.
