In general, Topcaptchasolver is a browser hijacker that can make changes in your browser, redirect your searches to other sites that don’t really match your real interests, and show hundreds of pop-up ads and banners on each page that you visit. If Chrome, Firefox, Edge or another Internet browser gets hijacked by Topcaptchasolver, you may notice a change in your homepage address or a replacement of the default search engine with a new one.

Most users normally don’t know if having a browser hijacker on their system is a bad thing or not and whether such software can harm their system. That’s why when they first hear the term “browser hijacker” they normally seek information about programs like Topcaptchasolver in the virus and malware section. Fortunately, browser hijackers are not a threat to a computer and when it comes to their functionality, they differ greatly from popular malware like Trojans, Ransomware and Spyware.
Apps like Topcaptchasolver are typically used as online advertising tools. Nevertheless, they are often considered potentially unwanted, despite their lack of harmful abilities. This is because their actions are related to an aggressive online advertising approach involving modifications to the browser settings and the generation of hundreds of unverified pay-per-click advertisements, banner messages, pop-up notifications, promotional links, and page redirect invitations. Modifications like these are not the worst thing that might happen to you but for many web users, it is disturbing that the browser hijacker makes them without asking for approval. This is why most users want to remove the imposed browser changes and uninstall the program that initiates them.
