What is topcaptchasolver[.]com?

Topcaptchasolver[.]com is used to promote untrusted, potentially malicious websites. It also can load dubious content, depending on the visitor's geolocation. In any case, topcaptchasolver[.]com cannot be trusted.

Note that users do not visit these websites intentionally. In most cases, they are opened after clicking deceptive ads, visiting other dubious pages, or by potentially unwanted applications (PUAs) that users have inadvertently installed onto browsers or operating systems.

There are many pages similar to topcaptchasolver[.]com online. Some examples are eouldeco[.]online, mekiroki[.]com, and sakh[.]site.

Typically, topcaptchasolver[.]com and similar sites open various other scam websites such as "Google Membership Rewards", "Norton Antivirus 2021 Update", "Your System Detected Some Unusual Activity", download pages for potentially unwanted applications (e.g., adware, browser hijackers), and other dubious sites.

Note that after visiting topcaptchasolver[.]com, it opens two or three other untrusted websites. These sites also use 'clickbait' techniques to trick its visitors into giving permission to show notifications: topcaptchasolver[.]com displays a fake CAPTCHA test urging users to click the "Allow" button to prove that anyone who has visited this page is not a robot. If allowed, websites such as topcaptchasolver[.]com show notifications with deceptive advertisements and links to potentially malicious sites. Do not allow topcaptchasolver[.]com or other dubious sites to show its notifications.

Apps used to promote pages such as topcaptchasolver[.]com display advertisements and collect data. They serve coupons, pop-ups, banners, surveys, and other ads used to advertise potentially malicious pages. In some cases, they execute scripts designed to download and install unwanted software.

Examples of details collected are IP (Internet Protocol) addresses, addresses of visited websites, entered search queries, geolocations, and other data. Some PUAs that can read sensitive information. The data is sold to third parties (potentially cyber criminals), used for marketing purposes, etc.

Therefore, never allow PUAs to be installed on the operating system or browser.

In summary, users do not often visit web pages such as topcaptchasolver[.]com intentionally - they are forced to visit them due to PUAs installed on browsers. Although advertised as useful and legitimate, most of these apps are useless and can cause serious issues.

As mentioned, users often download and install potentially unwanted applications inadvertently.

How did adware install on my computer?

PUAs are distributed via download/installation set-ups of other products. This deceptive marketing tactic of packing regular software with unwanted or malicious additions is called "bundling".

Rushing download/installation processes (e.g. ignoring terms, skipping steps and settings, etc.) increases the risk of inadvertently allowing bundled content into the system.

Some PUAs have "official" download sites. Intrusive advertisements proliferate these applications as well. Once clicked, they can execute scripts to download/install PUAs without users' consent.

How to avoid installation of potentially unwanted applications

You are advised not to use Peer-to-Peer networks (such as eMule, torrent clients, etc.), unofficial websites, third party downloaders, installers, etc. to download or install software or files. Use official pages and direct links.

Check download/installation set-ups for settings such as "Advanced", "Manual, or "Custom" (or include certain checkboxes) and decline offers to download or install unwanted apps before completing the process.

Additionally, do not trust or click advertisements that are displayed on dubious web pages - they can open other rogue sites or cause unwanted downloads and installations.

Remove any suspicious or unknown extensions, add-ons and plug-ins installed on the browser. The same applies to software of this kind that is 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.
