Browser hijacker is a kind of software that is developed to change the browser settings without the knowledge or permission of the computer user, and it usually redirects the affected system’s web browser to certain advertisement-related web sites. A browser hijacker installs multiple toolbars on the web-browser, redirects user web searches to its own web-site, changes the default web-browser search engine or start page, generates multiple pop-up advertisements and initiates numerous popups. If your web browser is affected by a browser hijacker you may need to follow manual steps or use a malware removal tool to revert changes made to your web browsers.
The PDFFreeSearch browser hijacker will modify your browser’s search engine so that all searches are sent through feed.pdffreesearch.com which redirects to the Bing Search engine that shows the search results for your query. The authors of this browser hijacker are utilizing legitimate search engine as they may earn revenue from the advertisements that are displayed in the search results.
