What is Delta Search?

Delta Search is a browser add-on that affects browser settings by installing a toolbar and changing the main page. While it may look as an innocuous expanding of search functions, we recommend neither using a toolbar, nor performing a search on the www.delta-search.com page, as they both are parts of the Delta hijacker. And hijackers usually amend search results in order to promote third-party sites and services. Therefore victim would visit unwanted sources, which may lead to getting more infections. To prevent that you need to remove Delta Search as the source of dangers.
