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 is malware and adware. 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.
Download Valley is a cluster of software companies in Israel, producing and delivering adware to be installed alongside downloads of other software. The primary purpose is to monetize shareware and downloads. These software items are commonly browser toolbars, adware, browser hijackers, spyware, and malware. Another group of products are download managers, possibly designed to induce or trick the user to install adware, when downloading a piece of desired software or mobile app from a certain source.
A potentially unwanted program (PUP) or potentially unwanted application (PUA) is software that a user may perceive as unwanted or unnecessary. It is used as a subjective tagging criterion by security and parental control products. Such software may use an implementation that can compromise privacy or weaken the computer's security. Companies often bundle a wanted program download with a wrapper application and may offer to install an unwanted application, and in some cases without providing a clear opt-out method. Antivirus companies define the software bundled as potentially unwanted programs which can include software that displays intrusive advertising (adware), or tracks the user's Internet usage to sell information to advertisers (spyware), injects its own advertising into web pages that a user looks at, or uses premium SMS services to rack up charges for the user. A growing number of open-source software projects have expressed dismay at third-party websites wrapping their downloads with unwanted bundles, without the project's knowledge or consent. Nearly every third-party free download site bundles their downloads with potentially unwanted software. The practice is widely considered unethical because it violates the security interests of users without their informed consent. Some unwanted software bundles install a root certificate on a user's device, which allows hackers to intercept private data such as banking details, without a browser giving security warnings. The United States Department of Homeland Security has advised removing an insecure root certificate, because they make computers vulnerable to serious cyberattacks. Software developers and security experts recommend that people always download the latest version from the official project website, or a trusted package manager or app store.
