What is fastcaptchasolver[.]com?
fastcaptchasolver[.]com is a rogue site that shares similarities with uploadhub.co, financeflick.com, captchatopsource.com, and many others. When this website is visited, users are redirected to other untrusted/malicious pages and/or are presented with dubious content.
Sites of this type are rarely accessed intentionally. Most visitors are redirected to them by intrusive advertisements or by Potentially Unwanted Applications (PUAs) already installed on their devices.
This software does not require explicit user consent to infiltrate systems. PUAs can have dangerous capabilities including causing redirects, running intrusive advertisement campaigns, and collecting browsing-related data.
The behavior of rogue web pages is determined by visitors' geolocations. The websites learn this information by checking users' IP (Internet Protocol) addresses. I.e., whether visitors are redirected elsewhere or are presented with dubious material depends on their geolocations.
Furthermore, sites of this kind tend to use deceptive tactics to trick users into enabling their browser notifications (e.g., they use 'clickbait', disguise the "Allow" option as CAPTCHA verification, etc.). This is the case with fastcaptchasolver[.]com - if the notifications are enabled, the website starts running intrusive ad campaigns. The delivered ads are more than just a nuisance, they also pose a threat to device/user safety. Once clicked, intrusive advertisements can redirect to dubious/dangerous sites and some can stealthily download/install software (e.g., PUAs).
PUAs can have varied functionality, and these functions can be in different combinations. For example, they can force-open harmful web pages and deliver intrusive ad campaigns.
Furthermore, most PUAs have data tracking capabilities. They monitor browsing activity (URLs visited, pages viewed, search queries typed, etc.) and collect sensitive information derived from it (IP addresses, geolocations, and even personally identifiable details). The gathered data is then shared with and/or sold to third parties (potentially, cyber criminals).
In summary, unwanted software can cause system infections, serious privacy issues, financial loss, and identity theft. To ensure device integrity and user privacy, all suspect applications and browser extensions/plug-ins must be removed without delay.

PUAs may seem legitimate and harmless, and users are often enticed into download/installation and purchase with offers of various "useful" features, however, the functionality seldom works as advertised, and, in most cases, does not work at all.
The only purpose of this unwanted software is to generate revenue for the developers. Rather than delivering any real value, PUAs cause redirects, run intrusive ad campaigns, and collect private data.
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 to research all software before download/installation or purchase. All downloads must be done from official and verified sources, since dubious channels such as unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders commonly offer deceptive or bundled content.
When downloading/installing, read the terms, explore all possible options, use the "Custom/Advanced" settings and opt-out of supplementary apps, tools, features, etc. Intrusive ads may seem normal and harmless, however, they can redirect to various dubious web pages (e.g. gambling, pornography, adult-dating, and many others).
If you encounter ads or redirects of this kind, inspect the system and remove any suspicious applications and browser extensions/plug-ins immediately.
If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.

Only allow notifications from websites that you fully trust. For added security - use an anti-malware application with a real-time web browsing monitor to block shady websites that tries to trick you into allowing spam notifications. We recommend using Combo Cleaner Antivirus for Windows.
