Fastsolvecaptcha.com

Fastsolvecaptcha.com is a browser-based tactic through which threat actors deliver advertisements to target devices directly. This empty website reaches for a common questionable tactic to fulfill its purpose – it displays a fake message disguised as a CAPTCHA-verification test that is supposed to confirm the visitor is not a robot and ask users to click on the 'Allow' button. As you can imagine, clicking on the 'Allow' button has the only purpose of giving this website permission to deliver push notifications to users' computers.

Pop-ups generated by Fastsolvecaptcha.com promote online gambling sites, pages with adult content, fake software, and other potentially harmful products and services. However, they can be very annoying as well, as they show up all the time, even if no Internet browser is launched. Furthermore, many of these advertisements may contain links to other compromised websites where users can get infected with malware.

Users can withdraw Fastsolvecaptcha.com's browser notifications permission any time. However, they should check their device for malware additionally. One reason is that such pages are visited intentionally rarely; more often, people land on them through an adware program installed on their computer.

Potentially Unwanted Programs (PUPs) like adware sneak into computers unnoticed. Still, their presence does not remain hidden for long: undesired advertisements and a sudden change in the browser's behavior (new homepage, new tab URL, and default search engine) signal the computer has been comprised. A data breach is another severe issue caused by adware and browser hijackers as many of them have functionalities to collect the user's information. Anti-malware programs can help you detect PUPs on your system and remove them efficiently with no traces left.
