If you are a user who is facing a browser hijacker for the first time, then you surely have a lot of questions about the nature and the purpose of an application like Justcoolcaptcha.top. Luckily, these applications like Justcoolcaptcha.top are not viruses and do not pose a direct threat to you or your system.
In fact, applications of this type are usually perfectly legitimate and are not intended to harass you like a Ransomware cryptovirus or a Spyware infection. However, there are a number of reasons why the browser hijackers are classified as potentially unwanted and why the users may want to remove them. The aggressive ad generation, the browser changes and the automatic page-redirects are the most obvious ones but another one of these reasons is the method of distribution of these applications. Most users usually don’t have a clue when and how a piece of software like Just cool captcha can get installed in their system. And this is mainly because the browser hijackers are typically bundled in the installation wizards of other applications that people willingly download and install on their PCs. However, since the presence of the hijacker in the installation package may oftentimes not be clearly disclosed, one may need to specifically click on the Advanced or the Custom menu in order to find and disable the added hijacker component. However, most people don’t pay close attention to these settings and that’s how many end up with such additional software without actually wanting it.

Just cool captcha is a type of marketing software that spreads via file-bundling and aims to get installed in the user’s main browser in order to flood it with ads. To be more effective at advertising, Just cool captcha may also replace the browser’s default search engine and homepage.
If you’ve noticed any sort of unusual browser behavior, including sudden page redirects to obscure sites, the display of annoying ads even when visiting websites that don’t normally have them, or changes in the starting page and/or the search engine of the browser, this almost certainly means that there is a hijacker like Just cool captcha in the browser.
The aim of Just cool captcha and other similar undesirable apps is to earn money for their creators by employing the popular Pay-Per-Click and Pay-Per-View methods. Those methods allow the hijacker to generate income from every click that users make on its ads and every visit from users to the sites that the hijacker promotes. While this sort of activity won’t directly damage your system, it can certainly put it in danger, so it’s advisable not to allow Just cool captcha to stay in your browser.
Just cool captcha is less dangerous if we compare it to Ransomware or a Trojan, but it’s still not a safe app and must therefore be deleted from your PC. One dangerous thing about Just cool captcha is that it can automatically reroute your browser to questionable sites.
The main issue here is that this sort of application is designed to promote anything, without any regard as to whether the marketed content is safe or reliable. In fact, in many cases, the appearance of the ads shown by browser hijackers may be misleading and deceitful so that, once you click on the ad, you get sent to a page that has nothing in common with what seemed to be getting advertised.
In this way, you could end up on unreliable or outright dangerous sites that are hosted by scammers and hackers and are designed to trick you, get you to share personal details, and/or persuade you into downloading malware.
To remove Just cool captcha, you should start by ensuring that you delete any recently-installed program that could have helped the hijacker infect your browser. After that, in order to fully remove Just cool captcha, you must also clean the browser from rogue add-ons and then clear its data.
Here are the main steps that must be performed to ensure that the hijacker is taken care of:
1. First, you need to check the Uninstall a Program/Programs and Features list in your Control Panel for any recent install that may be undesirable and delete it.
2. Next, check for rogue Just cool captcha processes in the Task Manager, quit them, and also delete their folders.
3. Also check the Hosts file, the network DNS settings, the Startup items, and the Registry and if the hijacker has added/changed anything in them, restore them to their regular states.
4. Lastly, go to your main browser, delete from it any add-ons you don’t recognize or trust, and delete the browser’s cookies, cache, and history. Then do the same with any other browsers in the system.
