The tool Booster Search should supposedly improve and “boost” your browsing experience, but this app is actually a browser hijacker that will attempt to redirect your browser search and homepage to feed.boostersearch.com. Search results will send you to malicious websites to get money from you or infect your computer further. This browser hijacker will also display unwanted ads on your screen, track your search queries and visited sites, and may prevent you from changing your settings back.
Feed.boostersearch.com is usually installed through bundled software without you knowing. In this case, it is the Booster Search application. It has to be removed immediately.
