What is captchareverse[.]com?
Сaptchareverse[.]com is a deceptive website designed to load questionable content and promote other pages of this kind. It is very similar to a great number of other sites.
A couple of examples are video-notification[.]digital, ngthatwe[.]fun, and ndmeeting[.]fun. Another thing that websites like captchareverse[.]com have in common is that users do not visit them intentionally.
Usually, users end up on them after clicking on deceptive advertisements, while visiting other questionable sites or when browsers have some potentially unwanted application (PUA) installed on them that regularly opens such pages.
When visited, captchareverse[.]com checks the visitor's geolocation/IP address and then loads its content or opens about two, three dubious websites. At the time of the research captchareverse[.]com opened a scam page virtually identical to "Browser Opinion Survey".
It is not uncommon for pages like captchareverse[.]com to open scam websites, or other untrustworthy pages, for example, deceptive download websites for browser hijackers, adware, and other unwanted software. It is important to mention that captchareverse[.]com and many other websites of this type show deceptive messages encouraging visitors to click the "Allow" button.
In other words, most of these pages use a certain clickbait technique to trick visitors into allowing them to show notifications. Captchareverse[.]com displays a fake CAPTCHA asking visitors to click the "Allow" button to prove that they are not robots.
Users who agree to receive notifications from pages like captchareverse[.]com constantly see notifications with links to potentially malicious pages in them, shady advertisements, etc. Therefore, it is advisable that pages like captchareverse[.]com should never be allowed to show notifications.
It is quite common that browsers that open websites like captchareverse[.]com have some potentially unwanted application installed in them (or there is one installed on the operating system). It is noteworthy that PUAs can be designed to generate advertisements (for example, coupons, banners, surveys, etc.).
Moreover, their ads can be used to advertise untrustworthy websites or even distribute unwanted apps by designing to start download or installation process by executing certain scripts. Another important detail about PUAs is that they can be designed to collect information about their users.
For instance, Internet Protocol addresses, addresses of visited websites, entered search queries, geolocations. Although, it is known that there are PUAs that can access not only browsing data but also personal, sensitive details.
Information collected by PUAs is likely to be misused for marketing purposes, sold to third parties (potentially cybercriminals), or misused to generate revenue in other ways.

By having apps of this kind installed, users risk to become victims of identity theft, encounter problems with online privacy, browsing safety, or other issues. It is worthwhile to mention that most PUAs are advertised as useful, but in reality, they are designed to generate revenue for their developers.
How did adware install on my computer?
Most users download and install potentially unwanted applications accidentally: through deceptive advertisements or when developers use a "bundling" method to distribute those apps. Advertisements can cause unwanted downloads or even installations when they are designed to execute certain scripts.
They start downloading or even installing unwanted software after they are clicked. In the second case users download or install potentially unwanted apps together with other programs, when PUAs are included in downloaders or installers as extra offers.
Users can find and decline those offers in "Custom", "Advanced" (or other) settings, or by unticking checkboxes that downloaders or installers for those programs have. When users leave those settings unchanged they also agree to download or install included PUAs.
How to avoid installation of potentially unwanted applications?
It is recommended to download programs from official websites and via direct links. It is not safe to use other channels for that, for example, third-party downloaders, torrent clients, eMule (and other Peer-to-Peer networks), unofficial websites, etc.
Third-party installers should not be used too. Also, it is advisable that downloads and installations should not be finished without checking downloaders, installers for "Advanced", "Custom" and other similar settings.
The main reason why those settings should be checked is that they often mention additional downloads, installations that can be opted out. Additionally, it is recommended not to click on advertisements when they appear on shady pages.
Quite often, users who click on those ads allow them to open untrustworthy websites or cause unwanted downloads, sometimes even installations Unknown, unwanted and suspicious extensions, plug-ins or add-ons installed on a browser (or programs of this kind installed on the operating system), should be uninstalled.
If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
