This type of scenario often occurs if you are not watchful enough while installing a new piece of software on your computer. That is why the file bundling method is so widely used – you can actually give your agreement for the installation of all software programs concealed inside while believing that you are only about to install one single program. Should you choose the all-time-favourite “Regular” step, you are likely to end up getting more than you’ve bargained for. To prevent installing Captcha-Smart.top or some other unwelcome computer software alongside the piece of software you actually want in your computer, simply choose the custom settings while in the installation wizard – in there, you will be able to see and uncheck any of the additional programs that seem to be questionable.

Some browser hijackers are more persistent than others. Therefore, if you cannot deal with Captcha-Smart.top manually, it is advisable to check your computer with the anti-virus application we recommend. Apart from hijackers, this software may also address other potentially unwanted and hidden dangers that might disrupt your system’s regular functioning.
Captcha-Smart.top is a browser-hijacking tool that infects browsers like Chrome, Edge, and Firefox, and turns them into ad-displaying platforms. The mission of Captcha-Smart.top is to market certain sites and products and thus generate money on the basis of Pay-Per-View and Pay-Per-Click.
The majority of users who have Captcha-Smart.top attached to their browsers don’t know how it got there, which can be attributed to the stealthy and underhanded tactics used to spread hijackers like it. Usually, the preferred methods of distribution for most browser hijackers are file-bundling, misleading online pop-ups, and disguised download buttons. These methods allow the creators of such software to get the software installed onto a big number of systems without needing the informed permission of the owners of the affected computers.
To protect your browser and PC from hijackers in the future, it’s strongly advised to never download anything that originates from questionable sources and developers, that could be pirated, and/or be of low-quality. It’s also important to keep away from sketchy-looking web ads and other online content that seems unreliable.
Captcha-Smart.top is fairly dangerous – although it doesn’t have the ability to directly harm your computer or files, it could lead to their exposure to other threats, including Trojans and Ransomware. Another thing that makes hijackers like Captcha-Smart.top dangerous is their data-gathering abilities.
A hijacker such as this one would typically extract information from the browser it is installed on and later use that information to present you with more relevant ads. On the surface, this may even seem useful. However, oftentimes the ads shown to you only seem to promote content that you may be interested in and when you click on them, they redirect you to something entirely different (and possibly unsafe). In addition, it’s not uncommon for data gathered by a browser hijacker to get sold to third-parties for extra profit. Who or what those third-parties are, however, remains unknown to the user. It’s not beyond the realm of possibility that your data could eventually fall into the possession of hackers or scammers, who could, in turn, use that data to scam you and/or attack you with malware.
To remove Captcha-Smart.top, you should make sure that there’s no rogue data, software, or processes in the system before you attempt to clean your browsers. Also, to remove Captcha-Smart.top, you must clean every browser in your system and not only the main one.
Here’s what the removal process of Captcha-Smart.top should generally look like:
1. First, you need to start with the programs that are installed on your PC – if there are any recent ones that you don’t seem to recall installing and/or that seem untrustworthy, you should probably uninstall them.
2. Next, you have to make sure that no rogue processes are active in the system – use the Task Manager to single out the ones you think are rogue, look them up, and if your suspicions are confirmed, quit them.
3. Later, you must also restore the default state of the Hosts file, the network DNS settings, the list of Startup items, and also you must clean the Registry.
4. Last but not least, you should go to each browser, uninstall any suspicious/unwanted extensions, and delete the browser’s cookies and cache.
