What is captchaverifier[.]top?
Captchaverifier[.]top is a rogue website sharing many similarities with captcha-bros.com, news-bobicu.cc, typiccor.com, financesurvey365.org, and countless others. This page is designed to load dubious content and/or redirect visitors to different sites (likely unreliable or malicious ones).
Users rarely intentionally access such webpages; most get redirected to them by untrustworthy websites, intrusive ads, or installed PUAs (Potentially Unwanted Applications). This software can infiltrate systems without user permission and subsequently cause redirects, run intrusive advertisement campaigns, and collect browsing data.
Captchaverifier[.]top in detail
The behavior of rogue sites is dictated by their visitors' geolocations. The webpages learn their information by checking users' IP (Internet Protocol) addresses. This applies to captchaverifier[.]top as well. Hence, whether visitors get redirected elsewhere and/or are presented with questionable content - depends on their geolocations.
Additionally, most websites of this kind use clickbait or other deceptive content - to trick visitors into enabling their browser notifications. Captchaverifier[.]top is not an exception to this; it employs fake CAPTCHA verification for this purpose. Should the notifications be allowed, captchaverifier[.]top will start running intrusive ad campaigns.
The delivered advertisements are misleading, untrustworthy, and may even be malicious. They promote various rogue, unreliable, and dangerous sites. Furthermore, some of these ads can infiltrate software (e.g., PUAs) without user consent - once they are clicked on.
How do potentially unwanted applications operate?
Potentially unwanted applications can have different heinous functionalities, and these functions can be varied combinations. For example, these apps can force-open websites and/or deliver intrusive advertisement campaigns. What is more, PUAs usually have data tracking abilities.
Unwanted apps can monitor browsing activity (URLs visited, pages viewed, search queries typed, etc.) and gather vulnerable information inferred from it (IP addresses/ geolocations, personally identifiable details, etc.). The gathered data is monetized by being shared with and/or sold to third-parties (potentially, cyber criminals).
To summarize, the presence of unwanted software on devices can lead to system infections, severe privacy issues, financial losses, and even identity theft. Therefore, it is strongly advised to remove all suspect applications and browser extensions/plug-ins immediately upon detection.

Potentially unwanted applications in general
PUAs appear legitimate and offer a broad range of "handy" features. However, the advertised functions are seldom operational. Unwanted apps only aim to generate profit for the developers; hence, functionality and user safety are irrelevant. PUAs are designed to cause redirects, deliver intrusive ad campaigns, and collect private data.
How did adware install on my computer?
PUAs can be downloaded/installed alongside other products. This false marketing technique of packing regular software with unwanted or malicious additions - is termed "bundling". These supplements can be hidden within the "Custom/Advanced" settings or left unmentioned entirely.
By rushing through download/installation processes (e.g., ignoring terms, using "Easy/Express" settings, skipping steps and sections, etc.), users risk unintentionally allowing bundled content into their devices, thereby endangering the systems with potential infections.
Intrusive advertisements are used to proliferate PUAs as well. Once clicked on, the adverts can execute scripts to download/install this software stealthily. Some PUAs may also have "official" promotional sites from which they can be downloaded and/or purchased.
How to avoid installation of potentially unwanted applications?
It is highly recommended to research products before download/installation. Additionally, all downloads must be done from official/verified sources. Untrustworthy download channels, e.g., Peer-to-Peer sharing networks, unofficial and freeware websites, and other third-party downloaders - often offer bundled content.
When downloading/installing, it is advised to read terms, study possible options, use the "Custom/Advanced" settings, and opt-out from additional apps, tools, features, and so on. Intrusive adverts appear legitimate; however, they redirect to unreliable and questionable sites (e.g., gambling, adult-dating, pornography, etc.).
Should users encounter ads and/or redirects of this type, they must check their devices and immediately remove all dubious applications and browser extensions/plug-ins. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
