What Is Search.webshields.org?
If your browsers open to http://search.webshields.org/, or searching via the omnibar/search bar gets you search results, “powered by Google”, on the same site, a browser hijacker is at fault. A browser hijacker can be an application or a browser add-on that gets installed together with freeware from download sites and that changes browser settings – homepage, new tab page, startup page, search engine – making the user visit a certain site time and again. You may use instructions from this removal guide to uninstall the browser hijacker and remove http://search.webshields.org page from your browsers.
