The Tail Web browser extension promises to be the “best way to search” but in reality, it’s a browser hijacker that will attempt to commandeer your browser search and homepage. It will direct your searches through tailsearch.com. Search results generated from this fake search engine will send you to malicious websites to get money from you or infect your computer further. It may also collect and monitor your browsing habits, and prevent you from changing your settings back.
Tail Web is usually installed through bundled software without you knowing. Remove it immediately.
