Great Captcha Now

Great Captcha Now is a rogue application that infiltrates Chrome, Firefox, and other popular browsers, introducing to them unwanted changes and rerouting the user’s browser to obscure sites. Great Captcha Now is mainly distributed using software bundles and disguised permission notifications shown by fake webpages.

Great Captcha Now

Many web users have recently been reporting that their browser has been taken over by an annoying application called Great Captcha Now. Great Captcha Now pretty much resembles a normal browser extension but its behavior is quite different. Instead of offering some actual functionality, Great Captcha Now tends to change the browser homepage or search engine and initiate automatic page redirects to different sites filled with pop-ups and banners.

It is very likely that, if you have in your Chrome, Firefox or Edge browser, you will be subjected to an aggressive online advertising campaign, typically related to pay-per-click remuneration models and sponsored ads positioning. With your browsing sessions may frequently be interrupted by different messages that might be prompting you to click on a given offer, download some software or purchase and test a product or a service.

In some instances, if you are not careful and get tricked into clicking on some of the links, you may not even realize how you may land on some shady web location or get exposed to direct security hazards. And while this is definitely not the goal of an application like Great Captcha Now or Great Captcha Snow, keeping it on your computer and letting it redirect you to different third-party sites can definitely increase the chances of accidentally coming across real virus threats including Trojans, ransomware or spyware.

That’s why it is generally advisable if you remove and uninstall the browser hijacker from your system. If you don’t know how to do that, in the removal guide below we have posted manual instructions that can help you. There is also a professional removal tool for those of you who may find it difficult to complete all the steps in the guide on their own.

If you are wondering how you may have ended up with a piece of software like Great Captcha Now on your PC, then you probably need a better understanding of the most common distribution methods that the browser hijackers use. Generally, most malicious pieces of software such as ransomware, spyware or Trojans can infect the system in stealth, without your knowledge.

Great Captcha Now, however, is not a virus and it normally cannot infect your system on its own. The most probable way you can end up with it is if you download it and install it (without realizing it) alongside some other software, an update or a browser add-on. Usually, the hijacker is attached as a free or a bonus component to the main installation package of different games, free tools, optimizers, document readers and similar helpful software. If not specifically disabled from the Advanced or the Custom setup menu, the advertising software typically gets installed by default when the setup process completes.

That’s why, if you really want to ensure that your computer doesn’t get invaded by similar nagging software, you should always pay close attention when performing software installations and manually remove any pre-selected free or bonus components that can make changes to your browser and its settings. Otherwise, if you miss these customization steps, you may need to uninstall the unwanted software later, with the help of a removal guide like the one above.

Pay attention to programs with strange names or apps that were installed at the same time as the hijacker.

    Once you’ve finished removing the unwanted programs, go to the Windows Search field, type msconfig in the search field and click on the System Configuration icon:


    In the Startup tab, look for items that aren’t associated with any of the default programs that Windows launches when it boots. If you identify startup items that you feel were introduced by Great Captcha Now, uncheck their checkmarks. Once you’ve finished, click OK to save your changes.

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

    In the text, look for suspicious-looking IP addresses under Localhost to see if any changes have been made.
