Captcha Reverse Virus

Captcha Reverse

Captcha Reverse is an ad-generation application that is known for its ability to fill the users’ screen with nagging web ads. Aside from that, Captcha Reverse can automatically redirect user searches to pre-defined webpages and modify the default browser’s search engine and homepage settings.

The virus will display pop up ads and messages

You most probably have had a situation where you download software you need from a relatively safe website, click the “Approve” button without checking the installation options and when you finish the installation process and return to your browser (be it Chrome, Firefox, Explorer, or some other one), you find that one or more third-party toolbars, buttons, and components have appeared there.

If you are familiar with this scenario, then you should know that this is one of the most common ways that you can install a browser hijacker like Captcha Reverse on your system. To your relief, what has happened to you is very normal and many web users tend to be faced with the same issue when they install new software on their computers through automatic installation and free download sources.

Most people come to know that their browser has been hijacked when they start to experience an intrusive stream of different advertisements – banners, pop-ups, and links that redirect to unfamiliar sites. Bust most commonly, the change in the default browser’s search engine and/or the homepage address is the most obvious symptom. If you have Captcha Reverse on your machine, in the next lines, we’ll explain how to uninstall this program and remove all its modifications and potentially undesirable components. Even though such browser hijackers are not as dangerous as, say Trojan viruses or Ransomware, we advise you to pay close attention to the information that follows and carefully use the instructions in the removal guide below to deal with the undesirable software.

The Captcha Reverse Virus

The Captcha Reverse virus can be installed on your device along with another free app like, or when you communicate with spam, free installers, automatic updates, and advertising. The Captcha Reverse virus typically aims to modify your browser’s options without asking for approval because in this way it can display various sponsored ads, banners, and pop-up messages on your screen and redirect you to third-party websites that promote certain products and services without being interrupted.

The changes that Captcha Reverse can apply are not fatal for your system but their result is always the same: every time you start a new browsing session, you will be subjected to more advertising material than usual.

That being said, it is a good idea to remove this program before its pop-up ads and page redirects become an unbearable web browsing problem for you. Another good reason for uninstalling Captcha Reverse is that you can never tell where its messages can redirect you. There are sites and web ads that contain infected links where viruses and malware such as Ransomware and Trojans can be found. That’s why keeping a program that can auto-reroute you to unfamiliar web locations can contribute to your accidental exposure to such security hazards. If you follow the steps found in the guide below, however, you can restore your browser’s default settings and limit the redirect and the ad-generation activity.

Remove Captcha Reverse Virus

To remove Captcha Reverse from your Windows PC, you should first go to your browsers and clean them from undesirable hijacker components.

  1. Start by going to your main browser and selecting its menu.
  2. Access the Extensions section and look for hijacker-related items there.
  3. If you notice a suspicious item, click on Disable and then on Remove in order to remove Captcha Reverse.
  4. If there are other browsers in the system, repeat the previous steps with them.

If the hijacker still appears to be present after getting rid of any potentially unwanted extensions in all of your browsers, this means Captcha Reverse has likely made other changes on your PC that you must take care of. Read the next instructions to find out how to do that.

Advanced uninstallation steps for Captcha Reverse

While completing the next steps you may need to restart the computer and so, to make finding this guide easier when the system starts again, we suggest you bookmark it. Alternatively, you could have it open on your phone and read the instructions from there while going through the guide.

Step 1

First you must check your PC for unwanted program installs – hijackers are often bundled with seemingly harmless programs that users install without being aware of the hidden hijacker.

Access the computer’s Control Panel from the Start Menu and open the Uninstall a Program section. In the shown list of programs, look for entries added right before you started noticing the hijacker symptoms. If there’s a program or an app installed around that time that looks like it may be behind the appearance of Captcha Reverse in your system, select the program/app, then click on Uninstall (the button at the top), and follow whatever instructions appear on your screen.

  • Note: If the uninstaller asks you if you want to keep any data or settings related to the program, choose No.


Step 2


You should check your computer for unwanted processes and end anything you may find. For that, press Ctrl + Shift + Esc to start the Task Manager app and look in its Processes tab. The hijacker process could be named anything but it will usually consume lots of memory and CPU to stay active so look for resource-intensive processes that look unfamiliar. Look up the names of the ones that you think may potentially be linked to the Captcha Reverse hijacker and if the search results suggest that a given process may be unwanted, right-click on it in the Task Manager, open the File Location, and scan the files there with the free online scanner offered below:

    Task Manager1

    If malware is spotted in any of them, you should Quit/End the process from the Task Manager (select the process then select the End Process button), and then delete the entire File Location folder. If any of the files in it cannot be deleted at the moment, delete the rest, and proceed further with the guide. Once you are done with the final step, come back here and attempt to delete the Location folder one more time.

    Task Manager2

    Step 3

    Restart the PC into Safe Mode so that even if you didn’t manage to find the hijacker process(es) and stop them, they wouldn’t be allowed to run in the system while you are completing the guide. Helpful instructions on how to enter Safe Mode can be found in the linked page.

    Step 4

    Go to Control Panel > Network and Internet > Network and Sharing Center and click on the name of your network (the one the PC is currently connected to). Select the Properties option, then click on Internet Protocol Version 4, and click on the next “Properties”.

    There, the “Obtain an IP address automatically option must be selected – if it isn’t, click on it. Next, proceed to the Advanced settings’ DNS tab and delete any IPs that may be listed there. Once you’ve done everything, select OK on each window to apply any changes that you may have made.


    Step 5

    Open the Start Menu, copy paste this line “notepad %windir%/system32/Drivers/etc/hosts” in it, and press the Enter key. Check the bottom of the text in the notepad file that will open for odd-looking IP addresses and if you see any, send them to us in a comment below this article. Once we check them out (and determine if they are from Captcha Reverse), we will tell you if anything needs to be done about them.


    Step 6

    From the keyboard, press the Windows Key (the one with the Windows logo) and the R key. In the small search box (Run) that opens, type msconfig and then press Enter. Open the Startup tab in the System Configuration utility that shows up and check the items listed there. Anything that’s unfamiliar, suspicious, or with an unknown developer should be unchecked (the tick in the checkbox in front of it must be removed). Once this is done, click on OK.


    Step 7

    In the Run search box from the last step, type regedit, and hit Enter. When Windows requests your permission to allow the Registry Editor app to make system changes, approve by selecting Yes.

    Now that you are in the Registry Editor, you must know that there are many sensitive settings for your OS stored here. You will be required to find and delete Captcha Reverse entries from the Registry but you must be careful not to delete anything else or else additional problems for your system may occur. Therefore, it is strongly recommended that you request our help by writing us a comment on this page each time you are unsure if a certain item must be deleted. 

    With the warning out of the way, the next thing you should do is press Ctrl + F and type the name of the malware in the search field. Click on Find Next to begin the search and if an item gets found, delete that item.

    Regedit2 1

    Keep clicking Find Next and deleting what gets found in the Registry until there are no more items related to the hijacker.

    Next, find the following locations in the left panel of the Registry Editor:

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

    In them, you must look for folders with strange names that stand out from the rest. An example of that would be a folder with a very long name that looks like a bunch of random letters and numbers that have been put together. Any such items in those locations must be deleted. However, we once again remind you to consult our team through the comments section in case of uncertainty.

    Step 8

    Finally, you should once more check each of your browsers and clean them from anything that may have been added to them by Captcha Reverse.

    First go to the icon of the browser, right-click it, and select Properties. In the Properties window, go to the Shortcut tab and check the Target field. In it, there shouldn’t be anything written past “.exe” – if there is anything written there, delete it and select OK.


    After that, enter the browser, click on the menu icon (should be either in the top-left or top-right corner depending on what browser you are using), and then go to Extensions/Add-ons. For Chrome users, you must first select the More Tools option and there you will see Extensions in the submenu that shows up.


    Once you are on the Extensions page, disable all items that look suspicious and then delete them. It is important to first disable them because otherwise you may not be able to properly delete them and they might come back or simply not go away when you click on the Remove button.


    Next, visit the Settings page by clicking on it from the browser menu. If you are using the Firefox browser, click on Options from the menu.


    Select the Privacy and Security settings and look for a button labelled Clear browsing data (or something close to that) and click on it. Microsoft Edge users should find and select the Choose what to clear option.


    In the dialogue box that appears, check every box leaving only the Passwords one unchecked and then click on Clear Now to initiate the command. Wait patiently for the command to be completed without exiting the browsers – in some cases this may take a few minutes.


    If the problems with Captcha Reverse continue
