UniqDataCaptchaUniqDataCaptcha is a site-rerouting app of the intrusive software category known as browser hijackers. UniqDataCaptcha aims to show you ads and get you to click on them as well as to redirect your searches in order to earn advertising revenue for its creators.
A recently reported browser hijacker called UniqDataCaptcha has been disturbing the web browsing of some users as of late and has been redirecting them to unfamiliar promotional sites. This application is not some sort of nasty Ransomware virus or a Spyware infection and has been developed to serve the needs of a group of online advertisers, who are trying to gain revenue from sponsored redirects and pay-per-click ads on the back of the unsuspecting web users. They have set their software to constantly generate different ads, pop-ups, banners and aggressive commercials on the browser’s screens and to manipulate users’ searches in such a way, so that they would click on certain sponsored ads.
UniqDataCaptcha can easily alter the settings of browsers such as Chrome, Firefox, Explorer and others and install some new homepage domains, a toolbar or a search engine there, which you may not be able to uninstall if the pesky hijacker is still present in the system. As a result, the quality of your web surfing experience may go down. The affected browser may start to bombard your monitor with lots of annoying ads and sponsored search results which are hard to get removed. If you happen to click on these messages, you may often find yourself getting redirected to different promotional platforms, new tabs and sites with questionable reputation. The content that you may come across may also be of poor quality and may lead you astray from the actual information that you might be searching for. UniqDataCaptcha may try to make you click on certain links and may ask you to download and install different free tools, questionable applications and obscure add-ons. It may also display sketchy offers, which may be too-good-to-be-true, and may often promote products and services which may be unknown to the market or simply unreliable. The idea behind this activity is to boost the traffic and the clicks to the sites of some third-parties that usually pay for such kind of aggressive online advertising.Why it is best to immediately uninstall UniqDataCaptcha
From a legal point of view, there is usually nothing illegal or harmful in the way UniqDataCaptcha and Humisnee operates. However, the browser hijacker may often employ some rather invasive online marketing methods such as the automatic page-redirects and the imposed browser changes mentioned above. It may also track your online activities to gather information about your preferences as well as cause issues such as sluggishness, crashes, and unresponsiveness to the affected browser. For these reasons, we usually advise our readers to uninstall the advertising software with the help of a professional removal tool or a manual removal guide like the one below.
UniqDataCaptcha is a browser hijacker type of a security nuisance. UniqDataCaptcha is categorized by the website redirects and pop-up ads it causes but it could potentially lead to even more serious problems.
Different free third-party applications, spam emails, suspicious websites, shareware platforms and other obscure software transmitters may oftentimes deliver a browser hijacker into your system if you happen to download and install their content. That’s why, to keep such annoying software away, it is advisable to avoid interaction with its most common sources. Also, another piece of advice about protection is to always pay attention to the installation settings when setting up a new program on your PC. Since the browser hijackers cannot actually infect a given PC in the same way Ransomware viruses or Trojan horse infections could, they can often be found under the Advanced or the Custom installation menu of other applications. You can easily remove them if you select that menu and then you won’t have to deal with their ads and browser changes later.
Some threats reinstall themselves if you don't delete their core files. We recommend downloading SpyHunter to remove harmful programs for you. This may save you hours and ensure you don't harm your system by deleting the wrong files.
To remove UniqDataCaptcha, all of the following actions need to be completed:
- Search though the programs on your computer and if you find any suspicious ones, uninstall them.
- Try to find out if the hijacker process is still active, and disable it if it is.
- Remove anything unwanted from the Startup items list, the Hosts file, and the Registry that may have been added by the hijacker.
- The final thing you must do to remove UniqDataCaptcha is to restore all of your browsers to their normal states.
Read the instructions shown below and complete them on your computer to eliminate the rogue app from your PC and browsers.
Detailed UniqDataCaptcha Removal Guide Some hijackers may try to communicate with their creators’ servers over the Internet, and this may help them evade removal. To counteract that, we advise you to disconnect from the web while completing the next steps.
First, it is important to find out if there is a program on your computer that may be responsible for infecting you with UniqDataCaptcha (program-bundling is a common hijacker-distribution method).
Check what programs are listed in Control Panel > Uninstall a Program and if there’s a suspicious one installed right before you started experiencing the UniqDataCaptcha symptoms, then make sure to uninstall that program.
If during the uninstallation process, you get asked if you’d like to keep on the computer your personalized settings for the program you are trying to uninstall, refuse that offer and make sure that everything related to the program gets removed.
WARNING! READ CAREFULLY BEFORE PROCEEDING!
Even if you have seeimngly deleted the rogue program, this doesn’t mean that the hijacker is gone – you must therefore also check the Task Manager for any processes that may be related to UniqDataCaptcha and stop them.
The Task Manager can be opened using the Ctrl + Shift + Esc combination from your keyboard, so open it and check its Processes tab.
If there is a process from the hijacker in there, it will likely not have the name UniqDataCaptcha, but something that may help you identify it is high memory and CPU usage coming from a process that doesn’t seem linked to any resource-intensive program you currently have open on your PC. However, certain OS processes such as, for instance, Windows Update can also have high resources consumption, so before you try to quit a given suspected process, look up its name – this should help you figure out if it is a potential threat, as there would likely be tons of relevant information online about the likely origins of that process.
Another thing you can do to find out if the suspected process is a threat is to right-click it and go to the File Location folder. Then you must scan the files there for malware – the following free online malware-scanner can help you with that, so we suggest using it.
If any of the file in the location folder for the process turn out to be harmful, you will know that the process is rogue and must be ended. In such a case, right-click the process again, click the End Process option and after that delete the location folder with all of its files. If anything cannot be deleted right now, delete the rest and return later, once the guide is completed, to remove what’s left of the process’ data.
Step 3 It’s important to not allow UniqDataCaptcha to launch any of its processes again until you finish the guide. Therefore, you must now enter Safe Mode – this will keep any non-essential processes from automatically getting started on your computer.
Step 4 UniqDataCaptcha has probably made certain settings changes in your computer – you must revoke any such changes in order to fully eliminate the hijacker. We will start with the DNS settings – type ncpa.cpl in the search bar under the Start Menu, click the first shown item, and right-click the icon of the network that you normally use. Open Properties, select Internet Protocol Version 4, and open the next Properties window. If the “Obtain an IP address automatically” and “Obtain DNS server address automatically” settings aren’t selected, select them and continue to Advanced. There, open DNS, delete anything shown in the list, after that click the OK button on every window.
The next settings section you must go to is the Startup Items list – you can find it by typing msconfig in the Start Menu, selecting the first shown icon, and opening the Startup tab. The items on that list are programs and apps set to start automatically when the computer is started. Anything unfamiliar shown in the list should be unchecked. The same applies to any items that are listed with unknown manufacturers, unless you know for a fact that the specific item is safe and not a threat. After everything suspicious is unchecked, select OK.
Lastly, use the Start Menu yet again to paste in its search field this line “notepad %windir%/system32/Drivers/etc/host” and then open the file that shows up. This file, called Hosts, often gets targeted by rogue software and the way to know if it has been hijacked is to look at the text below “Localhost”. You should copy that text and post it below, in the comments section, and we will have a look at it and then tell you if your Hosts file has been hijacked and if you need to delete something from it.
If no text is present under “Localhost”, this means that the file hasn’t been hijacked, and you should directly go to the next step.
Step 5 Be careful when completing this next step – only delete items you are certain should be removed, and if you are unsure about anything, it’s always better to ask us rather than acting rashly. If the wrong item gets deleted from your Registry, different system issues may result from it. To find and enter the Registry Editor, press together Winkey and R, type regedit, and then hit Enter. When you see a pop-you window asking you if you are certain you want to allow the Editor to make system changes, click on Yes (you must be logged in to an Admin profile to be able to open the Registry Editor). In the Editor, go to Edit > Find, type UniqDataCaptcha, and select Find Next. If the search yields a result, delete the found item and search. Keep doing this until the Registry Find box stops finding items when you search for UniqDataCaptcha.
Next, visit these locations in the sidebar to the left:
- HKEY_CURRENT_USER/Software/Random Directory
- HKEY_CURRENT_USER/Software/Microsoft/Internet Explorer/Main
If you find in them items that have overly-long and random-looking names similar to this “3892yr839d892tj8923eu982t98ru9382dj2398j“, delete them.
Step 6 Once everything else is done, you should finally make sure to clean your browsers from anything unwanted that may be in them. Start with your main browser – first right-click its icon, click Properties, and then go to Shortcut. Check what’s written in (next to) Target and if there’s anything after “.exe“, you must delete it and then click on OK. After that, access the browser and select its menu. Most modern Windows browsers have their menu icons in the top-right corner (somewhere below the X button). The Opera browser has its menu icon in the top-left corner of the screen (a big red O). From the browser menu, go to Extensions (or Add-ons in some browsers). In the Google Chrome browser, you must first go to More Tools to see the Extensions option in the submenu that shows up. On the Extensions page, carefully explore the listed items – it’s best to remove everything that you aren’t familiar with or that hasn’t been added to the browser by you (or anyone else who uses the computer on a regular basis). Obviously, if you see an extension with the UniqDataCaptcha name or anything similar or an extension that you suspect of being linked to the hijacker, you should remove it too. Oftentimes, rogue extensions won’t go away if you simply click on their Remove buttons, or they would re-appear after you restart the browser. To prevent this from happening, try to first Disable the extensions you want to delete and then immediately select the Remove button.
Next, you should delete the browser data – to do this, first select the menu of the browser again, and click on Settings/Options.
On the Settings/Options page, find the Privacy and Security section and click on it (should be shown in a sidebar to the left). After that, select an option labelled Clear browsing data or something close to that. In Microsoft Edge, that button is labelled as Choose what to clear.
Every box in the window that appears next must be unchecked. The only box that shouldn’t have a tick in it is Passwords. After everything is set up, select the Clear/Clear Data/Clear Now button and wait for the deletion to finish (don’t close the browser even if it seems to be stuck – this process may sometimes take a couple of minutes if it hasn’t been done in a while).
Last but not least, remember that this must be done with all of your browsers and not only the main one.
If you are still having problems with UniqDataCaptcha If you are still struggling with UniqDataCaptcha and the manual methods shown here didn’t help, it’s probably best to either take your computer to an IT specialist or to clean the system with a trusted security tool that can take care of the hijacker. One possible cause for the hijacker’s persistence could be a malware threat that’s currently running hidden in the background. For instance, Trojans and Rootkits are often used to allow other rogue programs to remain active for longer than usual and to evade removal. If, however, you don’t have the time to take your machine to a professional, you can still easily fix the problem using the powerful and reliable anti-malware program linked in our guide. It has proven to be effective against both hijacker annoyances and more serious hazards, including Trojans, Spyware, Worms, Rootkits, and more and, therefore, we highly recommend it.
UniqDataCaptcha is a browser-hijacking extension for Chrome, Firefox, Edge, and other Windows-compatible browsers, and it is known for its aggressive ads and push notifications. Typically, UniqDataCaptcha gets added to the browser after a file bundle that contains it gets installed on the computer. This file-bundling technique is a very commonly employed method of spreading hijackers like this one over to as many computers as possible. The program/file bundle that carries the hijacker isn’t a virus and in fact could be a legitimate program such as a torrent client, video-editing software, and even a security tool. However, in the installer of that program, there’s a clause that, if enabled, would allow the automatic installation of the hijacker inside the browser. Once in the browser, UniqDataCaptcha would likely have the permission to impose various changes, such as to change the starting page and/or the search engine of the browser or to add new and potentially unwanted extensions. Although UniqDataCaptcha isn’t a virus and is mostly focused on online advertising, it is still a liability to your system’s security and should be removed.
UniqDataCaptcha is relatively dangerous because the changes it enforces in the browser could compromise the program’s security and open vulnerabilities that could result in hacker attacks. Although UniqDataCaptcha is less dangerous than a Trojan or a Ransomware virus, you should still ensure it gets uninstalled. There’s one other common way a hijacker like UniqDataCaptcha could get embedded in your browser that doesn’t involve the installation of a program that carries it. This other method uses misleading notification permission requests that the user gets shown in the browser. The permission request is presented to the user as something else (usually, a captcha-like element that must be interacted with in order for the user to be allowed into a certain site). However, if you click Allow on such a pop-up, instead of verifying that you are not a robot, you’d instead unknowingly give your permission to UniqDataCaptcha to flood your browser with push-notifications and perform other unpleasant actions. In such cases, it may actually be easier to rid your browser of UniqDataCaptcha, since there wouldn’t be any unwanted software that’s installed in the system and that you’d need to uninstall.
To remove UniqDataCaptcha and ensure it doesn’t come back in the future, you must first delete any program you think may have added the hijacker to your browser. After this, in order to remove UniqDataCaptcha, you must also clean the system settings and your browser. Step 1: Go to the Programs and Features list in the Control Panel, search for a program that the hijacker may have been bundled with, and uninstall that program. Step 2: Enter the Task Manager and search its Processes section for any processes related to UniqDataCaptcha. If such processes are found, quit them and delete their folders. Step 3: Open the Hosts file, the Startup items list in System Configuration, the DNS settings of your preferred network, and the Registry Editor, and check them for changes made to them by UniqDataCaptcha. Any such changes you may notice need to be reversed. Step 4: Clean the data and delete any rogue extensions from each of your browsers. Also, revoke the notifications permission that any suspicious and/or UniqDataCaptcha-related site may have in your browsers.
