Captcha2020[.]com is the address of an untrustworthy web page that is designed to promote other pages of this kind, or to load dubious, deceptive content. The Internet is full of pages like this one. Some examples of pages that are similar or almost identical to captcha2020[.]com are withoughtc[.]top, uspetenti[.]top and settings-chrome[.]com.

It is important to mention that users do not visit such pages on purpose. Typically, users unintentionally open pages like captcha2020[.]com by clicking shady ads while visiting other unreliable websites. It is also common that browsers open unreliable pages without user interference.

It usually happens when browsers have some potentially unwanted application (PUA) installed on them.

Depending on its visitors' geolocation, captcha2020[.]com loads dubious content or opens a couple of other unreliable websites. It is common that pages like captcha2020[.]com are used to promote download pages for browser hijackers, adware, various scam pages (e.g., "You've Made The 9.68-Billionth Search", "Pornographic Alert"), or other deceptive sites.

Therefore, neither the captcha2020[.]com page itself or pages that opens are trustworthy. It is important to mention that captcha2020[.]com asks for permission to show notifications.

Typically, if pages like this one are allowed to show their notifications, they start to serve annoying notifications with deceptive advertisements, links to potentially malicious pages, etc., in them. Also, captcha2020[.]com may ask its visitors for their mobile phone numbers, supposedly to receive a code that they would have to enter to prove that they are not robots.

No personal information should ever be entered on websites like captcha2020[.]com (or any other unreliable page). One of the reasons why browsers open shady sites (including pages like captcha2020[.]com) by themselves regularly is because they have some PUA installed on them.

It is important to mention that PUAs can be designed to collect IP addresses, geolocations, entered search queries, addresses of visited websites and other browsing data, or even personal, sensitive details. All or at least some of the data may be sold to third parties (potentially cyber criminals) or monetized in other ways.

Moreover, PUAs can be designed to serve banners, coupons, surveys, pop-ups, or other ads that, if clicked, would open potentially malicious pages or even download, install unwanted software by executing certain scripts.

Most PUAs are advertised as useful apps. Nevertheless, they are designed to gather various data, force users to visit questionable websites, display deceptive ads. In other words, they are designed only to generate revenue for their developers. PUAs can cause problems relating to privacy, browsing safety, their users are may even become victims identity theft.

Therefore, it is strongly advised to immediately uninstall PUAs that are installed on a browser or the operating system.

How did adware install on my computer?

Most users download or install potentially unwanted apps on their computers or web browsers through deceptive advertisements or together with some other software. Users cause unwanted downloads, installations via ads by clicking on ads that are capable of executing certain scripts.

Usually, ads of this type appear on unreliable pages. In other cases, users download, install PUAs when they are bundled with other (mainly free) programs: when downloaders, installers have "Custom", "Advanced" and other similar settings, or checkboxes and users do not change those settings (or untick checkboxes) before finishing downloads, installations.

How to avoid installation of potentially unwanted applications?

It is recommended not to use questionable websites, Peer-to-Peer networks (like torrent clients, eMule), third-party downloaders, installers as sources, tools for downloading or installing programs (or files). It is advisable to use official websites and direct download links only.

Downloaders, installers that have "Custom", "Advanced" and other settings or some checkboxes often include offers to download or install various PUAs. Therefore, downloads and installations should not be finished without checking them for bundled apps.

Furthermore, it is recommended to avoid clicking on ads that appear on questionable web pages. Some of those ads can be designed to run scripts that would download or even install unwanted software. Any unwanted apps (extensions, plug-ins or add-ons) that are already installed on a web browser should be removed.

The same should be done with programs of this kind that are installed on the operating system. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
