Wajam is a social search engine founded in 2009. Its main product, released in 2011, is a plugin or browser extension that alters users' search results by adding recommendations from the users' social networks.
Wajam is often distributed as part of a software bundle. Users will seek out and download one non-Wajam program, such as a screensaver or game, and find that Wajam was installed on their computer during this process. Because the user sought out the bundled software only, not Wajam (which came as part of the bundle), this bundling can lead to accidental installations without the end user's awareness or informed consent. Because of these unintended installations, Wajam has been identified by a number of anti-malware software programs (including Malwarebytes' Anti-Malware) and several computer security websites as a "potentially unwanted program." Since it is designed to access private data, it makes individuals who have unintentionally installed it feel at risk. Unwanted installations of Wajam also have the capability to "hijack" a browser's search functions and display undesired ads. The company reports that it has received complaints concerning unintended installations, and has posted directions on its website to uninstall the software. Wajam is also distributed as a standalone product, and Wajam is a TRUSTe certified company.
