What is clevercaptcha[.]top?
Similar to fugles.net, news-lipaze.cc, premium-shops-around.me, and thousands of others, clevercaptcha[.]top is a rogue site. It operates by presenting visitors with dubious material and/or redirecting them to various (likely unreliable or malicious) websites.
Most users enter such pages via redirects caused by untrustworthy sites, intrusive ads, or installed PUAs (Potentially Unwanted Applications).
Clevercaptcha[.]top in detail
Whether visitors to rogue webpages are presented with questionable content and/or redirected elsewhere - depends on their IP addresses/ geolocations. This also applies to clevercaptcha[.]top.
Furthermore, most sites of this type use deceptive tactics to push their browser notifications. In the case of clevercaptcha[.]top, it uses fake CAPTCHA verification to trick visitors into enabling its notifications. Once enabled, the website will start running intrusive advertisement campaigns.
The delivered ads are misleading, untrustworthy, and may even be malicious. These adverts promote likewise suspicious and harmful sites. What is more, some intrusive advertisements can download/install software (e.g., PUAs) without user consent.

Potentially unwanted application overview
PUAs appear innocuous and offer "useful" functionalities, which typically do not work. Instead of delivering on any promises, unwanted apps can cause redirects (force-open sites), run intrusive ad campaigns, hijack browsers, and collect sensitive data.
To summarize, 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 together with other programs. "Bundling" is the term that defines this technique of pre-packing regular software with unwanted/malicious additions. By rushing through downloads/installations, users risk inadvertently allowing bundled content into their devices.
Upon being clicked, intrusive advertisements can execute scripts to make stealthy downloads/installations. Select PUAs also have "official" promotional/download sites.
How to avoid installation of potentially unwanted applications?
It is recommended to research software and only download from official/verified sources. Untrustworthy download channels, e.g., unofficial and freeware sites, Peer-to-Peer sharing networks, etc. - often offer bundled/harmful content.
When downloading/installing, it is advised to read terms, study available options, and use the "Custom/Advanced" settings to opt-out from all supplements. Intrusive ads appear legitimate; however, they redirect to highly questionable websites (e.g., gambling, adult-dating, pornography, etc.).
Should users experience adverts and/or redirects of this kind, they must inspect their devices and immediately remove all dubious applications and browser extensions/plug-ins detected. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
