What is reverscaptcha[.]com?
Reverscaptcha[.]com is quite similar to 1video-online[.]me, lootynews[.]com, romanticdating-day[.]com and a great number of other websites designed to promote a variety of untrustworthy pages and load deceptive content. Typically, pages like reverscaptcha[.]com are promoted through potentially unwanted applications (PUAs), shady advertisements, and other untrustworthy pages.
Reverscaptcha[.]com in detail
Usually, pages like reverscaptcha[.]com are designed to promote questionable pages. It is common that they open sites asking to provide personal information (e.g., names, surnames, credit card details, passwords), encouraging to download or install adware, browser hijackers (or other potentially unwanted applications), and so on.
A couple of examples of pages that sites like reverscaptcha[.]com usually promote are "Access To This Pc Has Been Blocked For Security Reasons", "SPIN FOR REWARD", "Google Membership Rewards".
It is known that reverscaptcha[.]com asks for permission to show its notifications. It is important to mention that websites of this type usually use some clickbait technique to trick visitors into allowing them to show notifications (into clicking the "Allow" button). This page displays a fake CATPCHA test encouraging to click the "Allow" button to prove that visitors are not robots.
It is recommended not to agree to receive notifications from reverscaptcha[.]com or any other similar website. The main reason why their notifications cannot be trusted is that they contain links to potentially malicious pages, questionable advertisements, etc.
As mentioned in the introduction paragraph, one of the ways to promote sites like reverscaptcha[.]com is to trick users into downloading and installing potentially unwanted applications. Apps of this kind can be designed to collect various data and generate advertisements.
Most PUAs target IP addresses, geolocations, entered search queries, visited pages, and other browsing-related data. There are PUAs that can read personal (sensitive) information as well.
Another issue is that collected details could be used for marketing purposes, steal identities, sell to third parties (potentially cybercriminals), or monetized in other ways.
Examples of advertisements that PUAs can generate are coupons, banners, surveys, pop-up ads. It is common for those ads to be designed to open questionable pages or execute certain scripts and then download or even install unwanted apps.

How did adware install on my computer?
Pretty often, potentially unwanted applications can be found in downloaders, installers for other programs as additional, optional offers. This distribution method is known as "bundling".
Usually, those downloaders, installers have ticked checkboxes or "Manual", "Advanced", "Custom" (or other) settings, options. Users can use their settings to deselect unwanted applications/decline unwanted offers.
When users download or install programs without changing the aforementioned settings, they agree to download or install offered applications as well. It is worth mentioning that PUAs are offered in downloaders, installers for free programs.
How to avoid installation of potentially unwanted applications?
It is advisable to use official and trustworthy websites (and direct links) to download applications, files. Other sources like third-party downloaders (and installers), unofficial websites, Peer-to-Peer networks (for example, torrent clients, eMule), can be used to distribute potentially unwanted or even malicious applications.
Downloaders and installers that have optional offers should be inspected. Usually, they have "Advanced", "Custom" or other settings, or some checkboxes that can be used to decline unwanted offers.
