What is current-captcha[.]top?
Current-captcha[.]top is a rogue website designed to load questionable content, push its browser notifications, and/or redirect visitors to various (likely unreliable or malicious) pages. There are thousands of such webpages on the Internet; clevercaptcha.top, positivestar.org, and news-hoyisa.cc are but a few examples.
Rogue sites are rarely accessed intentionally; most users get redirected to them by untrustworthy webpages, intrusive ads, or installed PUAs (Potentially Unwanted Applications).
Current-captcha[.]top in detail
The behavior of current-captcha[.]top is dictated by its visitor's IP (Internet Protocol) address/ geolocation. This data determines whether visiting users are presented with dubious material and/or redirected elsewhere.
Additionally, most sites of this kind use deceptive content to lure visitors into allowing their browser notifications. Current-captcha[.]top employs fake CAPTCHA for this purpose, and should its notifications be enabled - the website will start running intrusive advertisement campaigns.
The delivered ads are more than just a minor annoyance and endanger device/user safety. They promote various untrustworthy and malicious sites. Furthermore, some intrusive adverts can download/install software (e.g., PUAs) without user permission.

Potentially unwanted application overview
Despite their legitimate appearance, PUAs seldom operate as advertised. What is more, these applications can force-open pages, intrusive ad campaigns (adware), modify browsers (browser hijackers), and gather private data. The presence of PUAs on devices can lead to system infections, serious privacy issues, financial losses, and identity theft.
How did adware install on my computer?
PUAs can be downloaded/installed alongside together other programs. The marketing method of packing regular programs with various additions. Rushed download/installation processes increase the risk of allowing bundled content into the device.
Intrusive advertisements are used to distribute PUAs as well. Upon being clicked, the ads can execute scripts to make stealthy downloads/installations. PUAs may also have "official" download sites.
How to avoid installation of potentially unwanted applications?
It is recommended to research software and download it from official/verified sources. Dubious download channels, e.g., unofficial and freeware websites, Peer-to-Peer sharing networks, etc. - often offer bundled content.
Download/Installation must be treated with caution; that includes - reading terms, exploring available options, using the "Custom/Advanced" settings, and opting-out from all additions. Intrusive adverts appear legitimate, yet they redirect to questionable sites (e.g., gambling, pornography, adult-dating, etc.).
In case of encounters with such advertisements and/or redirects, the system must be checked and all suspicious applications and browser extensions/plug-ins detected - removed from it without delay. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
