Superfish was an advertising company that developed various advertising-supported software products based on a visual search engine. The company was based in Palo Alto, California. It was founded in Israel in 2006 and has been regarded as part of the country's " Download Valley" cluster of adware companies. Superfish's software has been described as malware or adware by several sources. The software was bundled with various applications as early as 2010, and Lenovo began to bundle the software with some of its computers in September 2014. On February 20, 2015, the United States Department of Homeland Security advised uninstalling it and its associated root certificate, because they make computers vulnerable to serious cyberattacks, including interception of passwords and sensitive data being transmitted through browsers.
