What is Onlinesearch.io

Onlinesearch.io is a fake search engine, using which should be ideally avoided or at least thought twice about. The common for all search engines requirement is providing users with relevant information, however, this requirement is not met in cases of hijacker’s pages. In fact, it is designed specially to garble the search results and inveigle people to sponsored sites. The Privacy Policy of Onlinesearch.io reads that its search result would combine highly commercial and algorithmic results collected from common search engines. Onlinesearch.io doesn’t dissemble this fact and openly states it in the License, but over the texts of EULAs are rarely read by users. If you are tired of redirections and want to avoid visiting obscure sites that use hijackers for promotion, you need to remove Onlinesearch.io.
