Clean Captcha

Clean Captcha is a problematic and unwanted piece of software that can get attached to Chrome, Firefox, and other popular browsers, and thus introduce unauthorized changes to their settings. Clean Captcha can replace the default search engine, change the homepage, and cause automatic page redirects.

If you have recently been noticing such unusual changes and behavior in your browser, then you are most likely dealing with an app like Clean Captcha. Generally, this type of software is referred to as browser hijackers – apps that take over the browser without the user’s informed permission and make changes in it that negatively impact the user’s browsing experience.

Cleancaptcha

For the most part, a software piece such as Cleancaptcha won’t perform any harmful actions on your computer. Its main goal is advertising-oriented: Cleancaptcha is designed to generate Pay-Per-Click and Pay-Per-View revenue through its ads and page redirects. It could also gather telemetry data from your browser and use it to better tailor its advertisements to your specific preferences. 

While none of those actions are harmful to the system, they could greatly decrease the quality of your browsing experience and interrupt your work. This, however, is not the main problem associated with hijackers like Clean Captcha, Bundle extension, Wave Browser. An even bigger issue is the fact that the ads they show might not always be safe and could get you redirected to online locations where scammers may trick you into sharing sensitive personal information or hackers may try to get you to download malware onto your computer. Therefore, even if Clean Captcha is not harmful by itself, it’s presence on your computer could easily, albeit indirectly, lead to your system getting infected by Trojans, Ransomware, Rootkits, or other malicious types of malware.

CleanCaptcha.top

Obviously, Cleancaptcha.top needs to be removed from your browser, but achieving this may not be as easy as uninstalling a regular program. The creators of most browser hijackers like Cleancaptcha.top make sure to make deleting their apps as difficult as possible, while still keeping the app legal and harmless so that it doesn’t get flagged and erased by antivirus programs.

The good news is that, even though it could be a bit tricky to get rid of Clean Captcha, it’s still perfectly manageable, so long as you know which parts of your system need to be cleaned from data and changes introduced by the hijacker. Down below, you can find a detailed guide that shows the exact steps that you’d need to perform in order to get rid of Clean Captcha. Note, however, that deleting the hijacker manually may sometimes leave behind rogue files and settings. To help you take care of those, we recommend using the professional anti-malware tool included on this page. It will scan your entire system, find every last bit of data and settings related to Clean Captcha, and delete them automatically from the computer.

Once you are done with the rogue app, you must also remember to keep your system clean and safe in the future by staying away from sketchy sites, avoiding interaction with suspicious online content, and only downloading new software that can be verified as legitimate and safe.

After you’ve finished with cleaning the browsers on your system, it’s time to search the most common system locations where Clean Captcha may have inserted its entries without your approval.

To do that, launch the Task Manager, (press the CTRL, SHIFT, and ESC keys on your keyboard), then choose the Processes Tab. You may find background processes linked to page redirects and ad-generation in there.

Right-click on any process you believe is hijacker-related, and select Open File Location from the menu that appears.

Scan the files in that place for hijacker-related code and other potentially harmful code using the sophisticated online virus scanner provided below.

    Step3

    Clean Captcha browser hijackers may be deployed in the system through software bundling, so it’s worth checking if any of the programs you’ve lately installed have brought the hijacker to your PC. To do that, press WinKey and R and type appwiz.cpl in the text field of the box. Click Ok and do some internet research if you need to learn more about the suspicious applications you isolate and the developers who created them, and then decide whether they should be removed based on the details you’ve discovered.

    appwiz

    Using the Start menu, enter “msconfig” in the search field, and then check the Startup items in System Configuration:

    msconfig_opt

    Remove the checkmark from any startup items that Clean Captcha has added to the list and then click OK.

    Step4

    The Hosts file is another place where the browser hijacker might make modifications. Use the Windows and R key combination to launch a Run box in which to paste the text below and then click OK

    notepad %windir%/system32/Drivers/etc/hosts

    Specifically, look for any suspicious-looking IP addresses under Localhost in the text that appears in your Hosts file:

    hosts_opt (1)

    If you see anything suspicious, please write a comment with a screenshot, and we’ll investigate and get back to you.

    Once you’ve done that, open Network Connections (type it in the Windows Search bar) and carefully follow these steps again:

    1. Right-click on your default network adapter and choose Properties from the menu.
    2. Select Internet Protocol Version 4 (ICP/IP) from the drop-down menu, and then click Properties.
    3. Select the Advanced option at the bottom after you ensure that Obtain DNS server address automatically is selected.
    4. Remove all rogue DNS addresses as indicated in image 4 by selecting the DNS tab and then removing it. Finally, be sure you click OK to save all of your changes.

    Step5

    Typically, a browser hijacker modifies the search engine or homepage settings of installed browsers in order to easily display more sponsored content on the screen. That’s why if you want to deal with Clean Captcha effectively, it’s important to repeat the steps below for every browser on your computer:

    Right-click the browser’s shortcut icon and then open Properties as shown below:

    browser-hijacker-taskbar-properties

    Next, click on Shortcut from the tabs at the top. In Target, remove everything that might have been added after .exe.

    Step6

    In order to stay in the system, a lot of browser hijackers make changes to the Registry by adding helper entries. To delete these hijacker-related entries from the Registry, you should scan it for them. The following is an example of how to go about it:

    Type Regedit into the Windows search bar from the Start menu, then click OK. When the Registry Editor opens, hold down CTRL and F at the same time. On the screen, a Find box will immediately open. Start a search by entering the name of the browser hijacker. If any matching entries show up in the search results, they should be deleted.

    Another way to check the registry for potentially unwanted Clean Captcha-related files is by going to the left-hand panel, and manually checking the folders listed below for anything unusual:

    • HKEY_CURRENT_USER—-Software—–Random Directory.
    • HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
    • HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random

    Note: Only remove files and folders associated with the software you want to uninstall. The stability of your system may be compromised if you make deletions or modifications to the Registry that are unrelated to the hijacker. Use a professional hijacker removal program, like the one on this website, if you have any doubts about your ability to accurately detect the Clean Captcha-related entries.
