StreamSiteSearch is a browser-hijacking app that mainly spreads via software bundle packages, resulting in a stealthy infiltration. Once installed, it sets homepage and new tab address to portal.streamssitesearch.com, applies a customized search engine and begins redirecting all search results to Yahoo. Additionally, the hijacker inserts sponsored links into these results and increases the number of advertisements users see while browsing the web.
