However, one of the most obvious signs indicating that you are currently dealing with a browser hijacker is the appearance of hundreds of unwanted advertisements on your computer screen. Ads like Index for Captchas, Rediroff.ru, etc. Typically, these adverts are displayed in the form of suddenly popping-up messages, banner ads, in-text links and similar notifications.

Once clicked, they may often redirect you to other sites where you may get tricked into downloading some software, installing some updates or purchasing products with dubious quality. Most of the ads may claim to help you save money during your online shopping sessions. However, you should be aware of the fact that it is not a good idea to click on every randomly displayed message that shows on your screen because, thanks to methods like malvertising, many hackers distribute threats like ransomware, Trojans and other nasty viruses.

It’s also an option to open the guide on your phone or other mobile device, which will provide you uninterrupted access to the instructions.

Next, using the instructions provided in this link, restart your computer in Safe Mode. The suspicious activities connected to the hijacker will be easier to detect in this way since the system will only execute the most essential apps and tasks

Step2

WARNING! READ CAREFULLY BEFORE PROCEEDING!

*Source of claim SH can remove it.

If you aren’t an expert it might be difficult to tell which processes on your computer are connected to the unwanted program. That’s why we’ve included a robust scanner in this step that you can use to check any process that catches your eye due to its odd name or unusually high resource use.

Click the Windows Start Menu button (bottom left of the screen) and type Task Manager into the search box, then press Enter.

In the Task Manager, select “Processes” (In Windows 8 and 10 select “Details”) and look for any processes associated with Great Type Captcha and its activities.

Right-click on any process that looks suspicious and select Open File Location to view its files:

malware-start-taskbar

Next, scan the process’s files for malicious code using the scanner provided below:

Each file will be scanned with up to 64 antivirus programs to ensure maximum accuracy

This file is not matched with any known malware in the database. You can either do a full real-time scan of the file or skip it to upload a new file. Doing a full scan with 64 antivirus programs can take up to 3-4 minutes per file.

    This scanner is based on VirusTotal's API. By submitting data to it, you agree to their Terms of Service and Privacy Policy, and to the sharing of your sample submission with the security community. Please do not submit files with personal information if you do not want them to be shared.

    To be safe, if any of the files are flagged as potentially harmful, you should End the processes (right-click on it and select “End Process“) and remove the potentially harmful files and their folders from the computer.

    If you find more than one suspicious process, you should scan its files as well in order to ensure that nothing questionable is operating on your system.

    Step3

    Ad-generating and page-redirecting activities may begin as soon as the computer switches on, especially if the browser hijacker has added one or more components to the startup list.

    To check if that is the case, use the Start menu search box to search for msconfig and hit Enter. After that, go to the Startup tab in System Configuration and uncheck the boxes next to any items you’re certain are associated with Great Type Captcha and then click OK to save your changes.

    msconfig_opt

    Step4

    In the fourth step, copy the following line and paste it into Start menu search bar:

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

    Open the file by pressing Enter and scrolling to the bottom until you see Localhost in the text. Let us know in the comments area below if you see a number of strange-looking IPs underneath Localhost (as shown in the image below). We’ll take a look at them and get back to you if anything has to be removed.

    hosts_opt (1)

    Next, search for Network Connections in the Start menu search bar and open it. Reverse any DNS changes that Great Type Captcha may have made by following the instructions below:

    1. Right-click on the default Network Adapter and choose Properties from the pop-up list of options.
    2. Select Internet Protocol Version 4 (ICP/IP) in the newly opened window, and then select Properties (located at the bottom).
    3. Choose Obtain DNS server address automatically and click on Advanced at the bottom.
    4. Open the DNS tab in the Advanced TCP/IP settings window and remove any rogue DNS entries from the field. Click OK to confirm your changes.

    Step5

    In the fifth step, you must search your system’s registry for files and folders associated with Great Type Captcha and delete them. The browser hijacker may re-install itself and start bothering you again if you don’t do this.

    It’s important to note, though, that any modifications or deletions that you make to the registry, which are not linked to Great Type Captcha, might have an effect on the general stability and performance of the operating system. For this reason, we suggest that you use a professional removal program to prevent any accidental system damage that may result from incorrect removals, especially if you are not an expert.

    The Registry Editor can be opened by searching for Regedit in the Windows search bar and pressing Enter.

    Inside the Registry Editor, press CTRL and F to enter the name of the browser hijacker that you want to remove. Delete any files and directories that are found by right-clicking on them.

    If you don’t get any results from the name search, you may manually search each of the following directories for new files and folders with suspicious names:

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

    In many cases, browser hijackers are delivered to the system via other apps and their installers, which include a hijacker component. If you just installed a new app, or if you believe there is software on your computer that has brought Great Type Captcha to your system, enter appwiz.cpl in the Start menu search field and hit Enter.

    Once the Control Panel window is opened, you can quickly remove any apps you suspect are connected to the browser hijacker. If you sort the applications by date of installation, you may be able to narrow your search to those that were installed around the time that Great Type Captcha began to bother you.

    appwiz

    Step6
    • If you want to remove Great Type Captcha permanently, it’s necessary to remove all hijacker-related components and settings that the hijacker may have installed without your permission in each of the browsers that you have on your system.

    To do that, right-click on the browser’s shortcut icon and select Properties, just as it is shown on the example image below:

    browser-hijacker-taskbar-properties

    After that, in the Properties window go to Shortcut. 

    Pay attention to the Target section and, remove everything that has been added after .exe.

    Next, open the browser that you want to check and click on its main menu icon. Typically, you can find it in the upper right corner for Internet Explorer, Chrome, and Firefox and in the upper left for Opera.

    Then, from the slide-down menu, select Add-ons/Manage Add-ons/More Tools and then click on the Extensions tab/sub-menu.

    In the list of Extensions, disable and remove any items that you believe may be causing interruptions to your Internet surfing.

    If you believe anything is part of the hijacker infestation but are unsure whether it has to be deleted or not, please use the professional removal tool that we recommend on this page or check any suspicious-looking file with our free online virus scanner.

    What is Great Type Captcha?

    Great Type Captcha is a rogue browser hijacker variant used for aggressive online marketing that uses underhanded methods to popularize different sites and products. The usual way Great Type Captcha is able to enter a computer is through the help of other software that it is bundled with.

    If you have recently installed any free applications or programs or if you have interacted with suspicious online links or permission requests and after that aggressive ads started appearing in your browser no matter what site you are visiting, then you have most likely been infected by a browser hijacker. This type of app is not as problematic as more advanced threats, the likes of Ransomware, Trojans, or Spyware, but is also definitely not something that you should allow to stay on your computer. In addition to being irritating with its ads, Great Type Captcha may also jeopardize the system’s security and cause other issues such as performance slow-downs, browser freezes and crashes, and more.

    How dangerous is Great Type Captcha?

    Great Type Captcha is relatively dangerous due to its uncontrollable stream of ads and the automatic page redirects that it’s likely to trigger. In addition, another factor that makes Great Type Captcha potentially dangerous is the changes it makes in the system that could lead to its exposure to malware.

    One of the most unpleasant characteristics of browser hijackers like Great Type Captcha is their ability to alter some of the system and browser settings. The reason they do this is twofold – on the one hand, they make those changes to be more effective at advertising various content from within your browser. This is why they may replace the starting page address or the default search engine as well as add new, mostly unwanted extensions to the browser. On the other hand, Great Type Captcha and other similar hijackers could also make changes in the system Registry, the Hosts file, or the network DNS settings. Such changes are introduced in order to make the hijacker more difficult to remove, thus increasing the time during which it will be present in the system which, in turn, increases the potential amount of revenue that the hijacker generates through ads.

    How to remove Great Type Captcha?

    To remove Great Type Captcha, it’s important to first clean your computer from rogue programs and processes before you take care of the browser. Once the system is cleaned, you can then remove Great Type Captcha from your browsers by deleting unwanted extensions and clearing the browser data.

    The following four steps give a general overview of how the deletion of Great Type Captcha needs to be performed for it to be effective and to prevent the hijacker from returning on its own.

    1. The first step is to check the Uninstall a Program section of the Control Panel and delete from it any recently installed program that seems untrusted and potentially related to the hijacker.
    2. The next step is to stop any questionable processes in the Task Manager that you have sufficient reason to believe are rogue.
    3. Thirdly, check the system Registry, the Hosts file, the Task Scheduler, the DNS settings, and the Startup items for hijacker-introduced changes and revoke any such changes.
    4. Finally, uninstall any rogue/unknown extensions from all your browsers and then clear the cookies, caches, and history of the browsers.
