Tika-search.com is a browser hijacker which modifies your default search engine settings and tunes them up in order to fulfill its covetous plan. The reason why such browser hijackers are developed is because their owners earn pretty good money through display of various paid online ads that are shown together with the search results. Plus, the domain tika-search.com becomes the home or start page of each browser you have installed on your computer, and it also serves as the default search engine of your browser.
